Diesel Oil, Flat Tappets & Gas Engines
"Zinc" or "Phosphorus" on an oil bottle label usually is referring to the additive zinc dialkyl dithiophosphate (ZDDP). ZDDP helps prevent wear, especially where the camshaft contacts the lifter in flat tappet lifter engines. Newer engines (since the late 1980s) have roller valve lifters and therefore do not benefit as much from ZDDP.
The anti-wear benefits of ZDDP were recognized in the 1950s. The oil of the 1950s had only about 300 parts per million (ppm) ZDDP. The concentration of ZDDP in motor oil gradually increased until it reached a maximum of 1200 to 1400 ppm in the 1980s. (More than 1400 ppm of ZDDP in oil actually starts to increase engine wear.)
Unfortunately, it was discovered that ZDDP makes catalytic converters for gasoline engines less effective by gradually coating the catalyst material with phosphate. To satisfy the latest API Service "SN" oil standard, oil manufacturers only put 600 to 800 ppm ZDDP in their oil.
Valvoline VR1 Racing OilFor over a decade, car enthusiasts with flat tappet lifter engines have been debating whether the 600-800 ppm ZDDP in new "SN" oil is enough protection. Oil experts say that it is enough wear protection once the engine is broken in.
The flat tappet lifter equipped engines in my family fleet were all broken in around a half century ago. I still like to dote on my old cars by giving them a little extra ZDDP as long as it does not require too much hassle or extra money. Valvoline VR1 Racing Oil has been one convenient option. It does not qualify for the "SN" rating because it has too much ZDDP and it is "not recommended for extended use in vehicles with catalytic converters."
Another new, less expensive possibility may be the 10W-30 oil made for some of the most modern diesel engines. Some old car enthusiasts have long recommended oil for diesel engines because it frequently contained more ZDDP. Unfortunately, diesel oil was typically only available in a heavy weight such as 15W-40.
Motorcraft's 10W-30 Oil for DieselsThe label on Motorcraft's 10W-30 oil for diesels says it "contains more than 1000 ppm phosphorus for better wear protection." That is 200 to 400 more ppm at little or no additional cost compared to "SN" 10W-30 oils. The Motorcraft diesel oil label also says, "do not use in gasoline engines equipped with catalysts."
I am testing the Motorcraft 10W-30 for diesels in the 351 under the hood of my 1971 Ford LTD convertible. However, I am not recommending that anyone else use oils labeled "diesel" in any gasoline engines. Please consult your vehicle's owners manual, the appropriate authorities, legal council, etc. before choosing a new type of oil for your specific engine. (For most vehicles, simply look under "Engine" and "Oil" in the RockAuto.com catalog to see manufacturer recommended choices. Oils listed by weight (10W-30, 0W-40, etc.) are found in the "Tools & Universal Parts" tab, under "Engine" and finally "Oil.")
Tom Taylor,

sorry Last indian, it was my fault spelling error!! i ment... " but i CAN completely understand your oil colour diagnosis"😜
i completely agree with Justa about oil in cars you bought being black and within weeks your new oil going the same colour.
i have a van that has had oil changes under warranty for its first 100000 kms by the the dealership, and i can see build up of black muck at the oil cap, it was being changed every 10000kms as per warranty.
now that is out of warranty i do the oil changes myself to save me $400 each time !!😡and every change,that oil is just dark brown black very dissapointing for a engine thats now only at 130000kms
Yup! That’s what happens & there’s no way to do it right except pull it tear it apart & rebuild it 🤭. Or leave it and just keep changing the oil every 500 miles till it stops! And I’ve never done that to a really dirty sludge up motor so I can’t say it would stop! 😳! New oil, because of the high TBN + new detergents etc. will clean varnish & sludge from that type of motor very quickly, but only till the contamination level overwhelms/depletes the TBN & additives. Which happens very quickly! So you need to remove that oil or it will simply rebuild what it removed. When we run an oil test in an engine, a clean engine, then we run a new test in that engine we do at least 2 full flushes. Depending on the oil the test and the engine it can be three and the flush times can be anywhere from an hour to 150 miles!

Gets darker over the life of the oil.
Coffee color= Change it......
BUT....... I have bought mainly used cars over the years. Have changed the dark oil w/specks only to have the new oil get dark within with in a week or two. You can bet there is burnt sludge in the valve covers and whatever migrated to the oil pan and maybe even pluggin your pickup screen. Have tried changing the oil w/detergent oils. Standard gas stations pushed that years ago when I worked there as a kid. Would change once a month with no cleanout or extended time before getting dark again. Valve covers are nothin to pop off and carefully clean out the sludge. Alot of cars you can't pull the oil pan without lifting or pulling the motor. An old mechanic (@ the Standard station) would run a quart of fuel oil and let run down and sit in the pan. Then run a cheap quart of oil through to clean out without starting. After a couple weeks, change the oil again. I was always shocked to see what the fuel oil cleaned out, but at the same time I was always wondering what was left floating around the pan. He never had anything come back to the shop with related problems. My point being, the oil can be brand new and still get dark in no time in older used engines that did not get the care most of us give our rides. The visual test can't be 100% for all engines, but I have always used your visual and smell test as a gauge.
Give my buddy JustA a cigar! Make it two! I hope nobody here thinks I think that I’m smarter of more accomplished at doing this! I’ve just done this a long long time & because of my line of work I got to see a very large array of conditions. So I have been able to correlate engine conditions to oil conditions. But to simplify it, most folks drain oil conditions, where there are no unusual circumstances, JustA’s statement is dead on!
Light color = NEW oil
Gets darker over the life of the oil.
Coffee color= Change it......
That smell! That’s a combination of fractured oil molecules, blowby & additives that have been oxidized. In tranny fluid, it’s oil molecules that have been fractured and additives that have been oxidized as well as fractured. Again the oxidation is obvious, by color! The tranny fluid goes from a crisp red or pinkish color, depending on which fluid. To a browner appearing fluid.
Oil as well as additive molecules fracture at about 350c, that’s 660f. Now you may not think your engine or tranny ever reach that temperature, but under certain conditions at very thin film thickness it can and does. Places like automatic clutch plates, bearing surfaces, etc.. I have done may test engine experiments where I thermal-coupled multiple areas of an engine or transmission, you would be astounded as to what temperatures reach in specific areas.The situation JustA specks of, as did I, with regard to the speckling in the oil & than in turn the sludge in an engine and cleaning it up! These are two different events, but they are interrelated. The speckling in the oil drop I spoke of above is from the natural combustion process (aka blowby) as well as valve train drain back! Also there is a portion that comes from the ZDDP! As I stated before, when ZDDP is not consumed through friction, read that as harder use, it stays in the bulk oil. Then eventually when the oil is in the engine long enough, being exposed to regular engine heat, blowby, the combustion process, a portion returns to the sump over and over again. This interacts with the ZDDP and creates sludge! This is why many older engines from the “60s”, “70s” & “80s” would have that thick sludge in them. That era ran the highest amounts of ZDDP in oils. This is why I have stated over and over, unless you’re racing or you are really running the car hard constantly, higher amounts of ZDDP are counter productive,. Because sludge in of itself causes wear!

Well! This is going to take some explaining to say the least & I have no doubt there will be skeptics! But,
this is something I’ve done since I was 14 years old! Yes I was young I know hard to believe! But I started working on cars @ 11 & racing @ 14. None the less I had done it so long it was just second nature to me. As I got more and more involved with specialty projects at work that centered around oil quality folks that I worked with were amazed at how accurate I would be about oil conditions when we would get test results back from samples we had taken and I had commented on at the time of extraction. I have always just used a white absorbent paper towel to wipe the oil on and then read the color. This is how I could judge the condition of the oil. In 1998 two colleagues that I had worked with for several years took some interest as to how I did this, so I tried to show them, but no matter how I tried they could not see what I would see! That led me to start working with black light to try to enhance the iridescent quality of the changing components of the oil. This helped some, but there were just to many irons in the fire at that time we all moved on to different projects. Than mid 2003 I approached our Vice President of research about the idea & if there was some way to take chemistry that would enhance a sample of oil when it was wiped on to a treated paper. So in early 2004 a patent was applied for to do just that. Now I’m not a chemist, I had learned much in 35 years, but not how to do that! So through some of my guidance we had arrived at a solution. It wasn’t perfect in my opinion, but I didn’t have the last word. If you what you can see that patent, just google US7754488 patent.Since then I have found some other ways that seem to enhance color observations better that just wiping oil on a white absorbent paper, which is what I typically have always done, no chemistry on the paper So now I will try explain & show as we go forward. Some of this I will need to figure out how or where I will get samples. As of right now I have oil samples I will show, but they’re all from health engines! Meaning the oil is just aged from use. These samples run from the indian (2000 Grand Prix) @ 500 mile, 2013 Buick @ 2800 & 2012 Buick @ 3300, which is just about due for an oil change!
So these are a good starting point, but you can also see, when present, fuel dilution, too much blow-by, coolant leaks, emulsion, excessive carbon & abnormal wear!the picture below! Left drop of oil is brand new Oil from my supply. The drop on the right is from the Indian, it has 500 miles on it. It’s a perfect color for the mileage.
this picture below is the Same as above with the addition of the bottom left drop being from 2013 Buick 3.6 direct injection. This oil has 2800 miles on it. If you look close you’ll see the red hue of the oil! You’ll also notice that it has the appearance of a darker center that seem to be speckled ever so slightly! The red hue is oxidation of the oil. The red hue is a good indicator of the oxidation level.
this picture below is again the same as above with the addition of the right lower drop of oil. This drop is from a 2012 Buick 3.6 direct injection. This oil has 3300 miles on it and needs changed soon! Notice the chocolate red color with no outer fringe of red, but if you look close again is an appearance of speckling. This indicates that carbon, varnish and heavy oxidation have taken place and the only thing that will now come from this oil is going to be more negative than the protection the oil can offer! Metal surfaces will start to varnish up & carbon will start to buildup!- 3

Most of the time, I'm runnin off the middle carb. She runs great. I rebuilt all 3 carbs a couple years after gettin the car on the road. Rebuilt again, replacing throttle shaft bushings. Helped the leak, but not the mid range bog. Accelerator pump is usually an off idle bog and dead give away. Thought I figured it out with the distributor, points or condenser and replaced with the Pertronix. Have tried adjusting the dwell all over the map and back to where it runs best. Condenser is workin or it's not. Never part time. Yea Gary... Re-adjusted the timing after installing. OMG. Young neighbor came over and asked what the chrome gun was for!!!! That's a timing light son...
Well first off that’s really sad! Funny, but sad! In another 15 maybe 20 years this country is so screwed! I’ve said it before I’ll say it again! When a country looses it ability to make machines of war their demise is eminent! We are just about there & this pandemic has only shown this to be truer than ever before!
Now to the important stuff! Two quick what if’s and thoughts! I would agree with you Steve, I don’t think it over fueled! By your description it sound like, 1. Lack of fuel, like the power circuit isn’t reacting quick enough! Maybe the spring valve is sticking? Or, 2. possibly a vacuum leak that needs a temperature rise to a certain point to cause enough of a gap to create that leak? I had that on my daughters “91” 3.4 Grand Prix! Intake manifold would create a vacuum leak after running long enough to create a gap at the gasket. What a pain to find! It happened in the winter. She was just out of college about a year and still at home here. So the car sat outside. So depending on the temperature of the day it would happen in varying lengths of time. While you don’t see an idle issue, that would mean it’s not an external leak, it could be an internal vacuum leak in the carb, maybe?

Excellent suggestions. The heat gun is buried somewhere in the storage unit with Lucy. Ditto the plastic spreader, the airbrush, and pinstripe kit....and I was too cheap to go buy another one.
The Goo Gone did a fine job it just took several applications and some rubbing.
Sorry, I forgot to mention it all looks good though! Except whatever that mess was in the air box! Really like the emblems, big difference!

Okay so the next two projects were on my 2018 Chevy Colorado. The first involved installing a Gator soft tonneau cover on the back. I got it for Christmas and finally the weather here in Michigan was decent enough in late April to install it. The kid helped me install it - in fact he kind took charge. It was a real easy installation. The most time consuming thing was setting up the tension blocks. They can be set up 4 different ways so you have a little trial and error to get it right to close the cover tight enough.
Here is the 8' long box everything came in. All you need is 1/2" socket, 9/16" socket and a flat blade screwdriver.
The kid doing the hard work - installing the C-clamps that holds the mounting rails to the side of the bed.
The finished product
The second project was replacing the Chevy gold Bowtie emblems with retro style Chevy emblems that Chevy used on their Heritage edition 100th anniversary pickups. You can get these emblems over the counter at your Chevy dealership. The front emblem is held in by clips that you release from behind the front grille. Just release the six bolts at the top, scrape up your hand and wrist quite a bit while pushing the pins out and viola, out comes the front emblem and you can push in the new one and bind a band-aid or two and some Bactine.
The tailgate was a lot more fun. By fun, I mean hassle, tedious, time consuming, etc., etc., etc. The back emblem is adhesively mounted. I had heard that dental floss and fishing line would work to cut the adhesive while not scratching the paint. I had lots of free unused dental floss samples but no fishing line, so I used that. It works - barely. It gets behind the emblem and you can start sawing away for a few seconds and then breaks. Get another piece, saw, break, repeat. Fortunately last summer I also invested in a set of plastic interior/emblem removal tools from Summit Racing for $27. Money well spent for this job. Once the floss got an edge started I could use the tools to get in behind the emblem and eventually pry it off without damaging it, the paint or the truck.
With the emblem off, now comes more elbow grease, getting rid of the old stick 'em. Goo Gone, paper towel and you !!! Yeah baby!
The tape marks all the points of the Bowtie so you can align the new one properly.
Success!
I know it’s a little late, but best luck I’ve always had is a heat gun and a auto body plastic spreader with a very thin edge. This usually just slices most of the adhesive tape and emblem right. Than just some cleanup with lacquer thinner.

Charged the battery and fired the GTO for the 1st time this year. Pulled it out N dusted it off. Yea NO DUSTOFF show this year. Installed the Pertronix ignition system and retimed the engine. Was hoping this would solve the mid throttle bog...NOPE. Cleaned the cap/rotor/contacts....still no. Ordered new cap/rotor. Pulled N cleaned N regapped the plugs. Better,but still there. Guess it's back to the carbs. Funny it fires right off, idles perfect, runs fine on the middle carb until ya jump on it. BOG then hold onto something, here we GO!!!! Have a driveby party tomorrow. So I get my 1st ride of the year. Wish we had some dust control down on these darned dirt roads.
JustA thought, but two things come to mind. I know you run tripower, but what about an accelerator pump? Also, did you check the distributor advance? JustA thought!

so, what happens if you use oil with a high zddp ?🙄
Specifically if you regularly run levels of ZDDP over 1500ppm and you just drive regular, no racing and not hot rodding all the time when driving you run the risk of the following depending on oil consumption rates!
ZDDP work by heat & pressure, but mainly heat! To explain it in layman terms! Because it’s a boundary layer chemistry it only gets activated when there is enough of each. If there isn’t enough it stays dormant in the bulk oil. When there is enough it builds a film. That film is self limiting, meaning when and if the layer builds thick enough it stops. When that film wears down enough it starts to make it again! So in racing, lots of friction, or hot rodding, the film builds up and shrinks continuously, which in turn depletes the ZDDP additive. When you drive more docile nothing much happens to the ZDDP! If you have enough blow-by or valve train leakage that allows oil to enter the combustion chamber; the results are excessive carbon deposits! Substantial more than without ZDDP, because the main byproduct of ZDDP is carbon!
So if you look at what I’ve been saying, and I might not have been saying it well enough! If you are racing or hot rodding, 1200ppm to a max 1500ppm! If you are driving street driving, more docile, getting on it hear and there, 830ppm to 1000ppm is more than enough. If you run a catalytic converter, 700ppm to 900ppm is enough. But the amount of oil that is consumed in the combustion process because of engine condition may change that!

Well it looks like i have been using the wrong oil!!
i was recommended amtex power 50...
https://oilintel.co.nz/product/amtex-power-50/
and i have been using it in both my stock 350 in the camaro and the hp 400 in the green ute also have been using it in the 59 plymouth with its 313 poly engine.
clearly my zddp levels are way too high
I see we dont get Rotella t4 here but is the rimula the same oil ?
Well looking at the Amtex I’m not that concerned! The ZDDP is at the top end of the top for regular oil, not break-in oil. While it’s 1500ppm the sulphated ash is quite low @ 9630! This has a offsetting effect for corrosion long term. Yes it appears that Rimula is a Euro version of the Rotella. The US & Europe have different chemistry because they both approach emissions differently.

that is my exact question Last indian! 🙄
when it comes to all the factors involved, as much as it is about the mix of additives etc in the raw oil, i would have to consider the engine its going into !
i have my old school engines, 313 poly, 389 pontiac, 400 and 350 chev, 360 magnum, that would ,most likely take one certain oil, but i also have brand new engines ( like my supercharged hemi) that need very specific oil, or is this just a myth ?
And what about cars like mine that sit for months without being started or used? how does that impact on the oil? do i need to change it more often because its been sitting?
Like my camaro is lucky to see 100 miles a year, some years none!, do i use a oil that is good for engines that get little use ???🙄
and here is a question for you, without giving away brand names... what tbn, zddp, tan numbers should i look for in a oil for say my 398 in the 64 ?
All good questions Kiwi! You are correct that different engines have different needs! So no it’s no myth! From both a base stock oil as well as additives. Still you can narrow the field of oils you need to a degree partly because oils, like lots of things tend to be backward compatible. Such as a GF6 oil is compatible for an engine that took a GF4 oil, but certain differences might rule out a particular oil, such as the unavailability of a viscosity grade!
Specifically you would need to look for a relative viscosity grade for an engine within a range. Example, if you have a motor that needs and uses a 20W50 Oil because of bearing tolerances, in turn it also runs no catalytic, plus you run it hard or race it! Than your not going to look for a Dexos oil because of their viscosity grades! You are additionally going to want a good anti-wear additive like ZDDP. You’ll want the range to fall somewhere between mid 700ppm which is a little low & 1200ppm, which is on the high side. This is all a lot of work so instead this is why I said you look for a fully formulated diesel oil like Chevron’s Delo 400 or Shell’s Rotella T4. Both have ample amounts of additives, including ZDDP.
Oil sitting in an engine for an extended period of time is ok! Unless the oil is nearing oil change time, than I would always change it before putting it up! Also I would change it if you have fuel dilution or a coolant leak! Even when these two items aren’t bad enough to be a detriment when driving regularly, they create oxidation and acid, so when left sitting for extended periods they tend to etch metal, which is corrosion.
Good numbers! TBN, well back in the day you use to be able to get a 13 or 14 TBN oil, today good luck! The highest I’ve seen is Delo Multigrade or Rotella T4 @ 10.1! Need I say more! That said in my opinion the Delo has to much zinc, @ 1500 & sulfated ash @ 14000! Where the Rotella has 1200ppm of zinc and 10000 sulfated ash, much more reasonable. TAN, that is a measurement taken as the oil is degrading and basically can only be made by drawing a sample and sending it to a lab for analysis, but! Good news! That is to be the next segment I start! How to analyze our oil at home by color!

What does it take to extend an oil drain? We once had a chemist at the company that was one of those guys that just walked to a different beat! He drove a ratty old car, never really did anything to it. This timeframe was late “70s” early “80s”! Never changed the oil, never! Every so often he’d pull a quart of oil out with a vampire pump and add a fresh quart! He ended up with around 140,000 miles on the motor. That was a lot of miles for a car back then, especially no oil or filter change! By comparison I had a 1967 Impala SS, change the oil every 3000 miles religiously, sold the car in 1975 with a 130,000 on it and that was nearly unheard of then! So you see the chemist was basically replenishing the additives on a regular basis. Now I don’t subscribe to that type of engine treatment, but the point is renewing additives does effectively extend drain intervals. Because additives are what give that life blood fluid its ability to keep the engine humming along.
THE NEED FOR ANTIOXIDANT ADDITIVES
When exposed to heat, oxygen and metal contamination, lubricants undergo oxidation. Base oils can perform many lubrication functions, but they can’t protect against the detrimental effects of oil oxidation.
Oxidation creates polymers, oil-insoluble high-molecular-weight molecules that increase the viscosity of the lubricant, accelerate wear and eventually leads to varnish. The hard “baked on” polymeric coating of varnish also accelerates wear and is a long-term detriment.
Oxidation also creates sludge, a soft oil-insoluble material made of combustion byproducts that suspend in oil. If it remains too long, sludge can plug oil lines and filters leading to oil starvation in the machinery and adhere to metal surfaces, accelerating wear. Along with other hard accumulations of sludge and varnish typically on pistons and valves in engines, deposits due to oxidation can cause valve and ring sticking, eventually leading to catastrophic increase in wear. There is good news however. Even though lubricant degradation processes are complex, the solution is straight forward. Antioxidant additives minimize oxidation and deposit formation. Detergents and dispersants also play a role in mitigating the effects of sludge and deposits.TBN gives an indication of the amount of base available in the oil to neutralize organic and inorganic acids that accumulate in the crankcase of engines during their operation. TBN or the quantity of base is expressed in milligrams of potassium hydroxide per gram that is required to titrate a sample, dissolved in a specific solvent to a specified endpoint. The importance of TBN has multiple impact on an engine! But not all TBN is created equally! Having a good TBN number means very little in the absence of a TAN number, why? Because they are not counter corresponding numbers, meaning as one goes up they other comes down! This is not true of all TBN! TBN has many influences, detergents, dispersants, etc!
There are two types of additives: bulk oil additives and surface additives. Bulk additives affect the rheological, interfacial and chemical properties of the lubricant, and surface additives are active at metal surfaces.
So how do we, the guy in the backyard, figure this all out as best we can without a lab at our disposal?!

Today nearly everybody seems to push for longer drain intervals, but why? Now oil manufacturers don’t, of course, but auto makers do, fleet owners do, the railroads do & EPA of course, again why? Money, what else! Oil companies aren’t in favor of it because they’ll loose money, less oil sold! Auto OEMs, fleet owners and the like want longer drains because it will save money! So what is right for the engine? Just extending drains doesn’t work! Putting in more additives helps, but is less than perfect for many reasons!
One thing that can and does work is replenishment of certain additives! In the mid 90s a team of four was formed by my company to pursue such an effort with a railroad company of which I was one of the four. Chemistry’s were gathered, equipment was designed and invented and testing was done! Concepts were proved and as we moved close to a operational launch, guess what! The OEM builder of the locomotive got wind of it! Because the rail company needed a sign off for engine warranty issues and that lead to a whole host of issues! Why? Because, you guessed it, they wanted a cut! This OEM is a huge corporation, bigger than both of us combined. Once they got involved it was just a slow death spiral that lasted 2 years!
A few years after this saga closed I entered another team of of 5 as I mentioned. This effort was successful with pass car. We developed a product, partnered with a filter company and had a successful product line. Not exactly the way we originally wanted it, but still successful. Yet what we were after was the trucking industry and extended drains! We were once again on our way, chemistry’s in place, equipment built & invented, over 2 million over the road test miles run and getting close to a launch time frame. This time we needed an OEM oil manufacturer sign off, so they sent a top PhD to the test engines tear down, big mistake! Once he saw the inside of these engines, we were done! He went back to California reported his observations and one week later our CEO got a call from theirs! We were to to cease and disease desist! Dead in the water! So what does it take to extend an oil drain?

i will do some hunting around to see if i can buy these here!!
i am sure my 389 engine deserves the good oil and my 313 poly and my 400 and 350 sbc and the ram 360, heck they may be best for the cortinas !
Last Indian.... What are you paying for this oil??
Kiwi, I’m not paying anything😁! Did I ever mention I worked for one of the largest specialty chemical additive companies in the world! One of the perks of running experimental testing! I think my reserve stock will take me well past my oil changing days!🤞
Checking online it appears you can get a gallon of T4, here for around $15.
It looks like the Valvoline syn runs about $20 a gallon. So again you see my point! The T4 is conventional oil, the Valvoline is syn oil, I would run both 3000 to 3500 miles for an oil change, but the T4, which I run in the Indian I Change every other year, which is usually between 1000 & 1500 miles. The point is the T4 has the full additive package that was always in both oils till they cut the pass car additive package in half. But the T4 is cheaper than the Valvoline! Really!!- 4

Yes! All of it! Just like a medical Dr. they use everything, if they’re good, to determine what’s wrong with you. It’s like that, but there is a leaning curve.
“and if you have a dirty engine whats the best way to clean it up without pulling it apart?” change the oil & filter, run 200 to 300 miles, drain, & repeat. Do this and increase the flush miles by 100 miles each time by the time you reach 1000 mile drain flush, if not before you should see a marked improvement in oil cleanliness! If not, it’s not going to get better!
Filters; there’s junk & there’s good stuff, but so many filter manufacturers have cheapened their products. Wix and AC Delco use to be the best, but even those two had cheapened some of their line with a plastic cage arrangement! The best filters have metal top & bottom caps that are glued. Many will argue that oil is so clean today good filtration isn’t needed, that’s just plan stupid! The filter is more about what comes from the engine itself or what it may ingest through engine breathing!
I personally have a stock pile of old style AC Delco’s that are the metal caps that are glued.
