Oil Change, obsessive? or just OCD?

So I thought I would just throw out my oil change procedure just to see if there are any like minded auto fanatics out there that use the same oil change thought process as I do or maybe even a better way to do it. So here it goes. A 2005 Chevrolet Corvette with an LS2 motor with 95K miles on the clock. I change my oil at evry 3K miles. I will NEVER be caught waiting until 7500 miles, or 10K miles, or 20K miles or changing my oil once a year nonsense that you see in commercials. The oil viscosity tech may have changed but we have yet to discover "self cleaning" oils.

I started a bit differently this time by letting the car sit for a week without the motor turning over at all to let everything settle to the oil pan. I haven't done this before because it really isn't practical as this is a daily driver.

So I get the car up on ramps without starting the motor. I set the parking brake and pull the oil plug and oil filter and a thick black dirty oil pours from the oil pan drain and you can feel the micro carbon grit in the dirty fluid. The DIC read "37% oil life" after 3K miles this oil change when it normally reads "50% oil life" in previous oil changes. I change the oil at 3K miles regardless of what GM or my DIC demands.

Next step is to replace the oil plug, screw on an inexpensive STP oil filter, and add 6 quarts of basic STP 5W-30 oil, start the engine and let it idle until the oil comes up to temperature and then shut the car off to let the "first oil change" as we will call it settle to the oil pan once again.

I again jack up the car, crawl under to once again remove the oil plug, oil filter, and wait until the last drop of oil falls from the oil drain. This time the oil comes out cleaner than the old oil and even cleaner than in past "first oil changes" and i think its because the old oil in the car got the opportunity to settle to the bottom of the pan for a week.

So last step in my oil change process is to button the bottom of the engine back up and this time add a top of the line oil filter and refill the crankcase with Mobil 1 5W-30 synthetic as the manufacturer recommends, put the car back on the ground, fire it up, let it get to temperature while looking for leaks, shut it off and then read the dipstick. I then slide a piece of clean cardboard under the car and come back in an hour and look for a leak to show up on the cardboard.

Is that all too much? is it crazy? is it obsessive? is it OCD? or are there OTHER car fanatics out there that have a similar procedure? a similar love for the care of their autos?

Do you have any similar oil change processes or ideas you want to share? and opinions on this procedure? my madness?

360, the only concern I have with what you are doing lies in something you didn't specifically state. What type of oil are you using for oil change #1?  If memory serves, the LS motors, particularly the Corvette motors all require synthetic oils. So I would make certain not to use a cheap conventional oil while trying to flush the remaining dirty synthetic oil out in change #1. I would try to find the least expensive synthetic or at the very least a synthetic blend. 

My reasoning is this, synthetic oils are for very tight tolerance motors, like the LS, modern Hemis, and Coyotes. So why risk possible cross contamination (and worst case - engine damage) between a conventional and a synthetic?  

Now if I am off base here and you aren't doing this, I have no concerns.

"What happens when you mix synthetic and conventional oil?"

According to Mobil Oil, it should be fine to mix oils. This manufacturer states it would be unlikely anything bad would happen, such as a gel-forming from an interaction of the chemicals (a common fear), because the oils are compatible with each other. In fact, many oils are a blend of natural and synthetic oils. Any SAE rated motor oil can be mixed with any other with no problems. That’s one of the requirements to get a SAE rating.
