Thread: 2004 Grand Prix using oil

My 06 uses a little oil, in fact to be honest I have never owned an internal combustion engine that did not burn a little oil over time. Sure, some use more than others but I consider anything less then a quart in 1000 miles to be acceptable.

On a new car I'd be pissed of course but at 100,000 miles a quart in 3K is more than acceptable in my book

I run 0w30 Mobil 1 in my GP and 0w20 in my wifes Honda powered vue. The Honda 3.5 with almost 90K on it burns around 1/4 of a quart in 8000 miles. The GP with the 3.8 at 44,000 miles around half a quart in 3000 miles or so.

Also, adding a 1/4 of a quart every time you check it is just a bit much for me. The engine tolerates a range of 1 quart. That means if your near the bottom of the range, or top it doesn't matter. I don't add until I'm a quart low unless I'm going on some long trip and assume I may dip below the minimal level. Same goes with my ATVs, I add when I'm approaching the bottom of the operating range on the stick. For some reason a lot of guys think it has to be to the top of the dipstick. In my opinion the "best" spot is dead center of the operating range.

from what i understand, engines make more power when a quart low too.

i think it was Edwards in nascar last year had a missing oil cap allowing oil to escape from the engine. i think they got a fine and some pts taken.

On our engines I'm sure they technically make more power a quart or even two quarts low. The poor crank is sloshing through the stuff.

Now on a dry sump setup its probably a different story.
