Seeing what you all think of this ld9 motors health  2000 Grand am with 229,894 miles . Ok so to it. Two oil changes ago I put seafoam in the motor as directed by the bottle. Ran it for 2000 miles then changed it came out black witch is normal for that type of thing. This last oil change I put 1/3 bottle of stp oil treatment and 10w30 oil. Ive gone 6000 miles on it and it only burnt 2/3 a quart of oil  and still has color. Just seeing what you all think of the health of the engine. Car runs great and no coolent leaks. I need to replace upstream o2 sensor .. think it will make it to 300k+ ???? BTW I normally always change oil at 3000 to 4000 miles.

Hey Lynn -  keep me posted on that miles thing.  I've got an 2002 GA with 36'000 on it.  Good to know it could well last over 200,000.
