No, take it to service. I don't burn oil like that and I take my 06 2.5 i out on track days and Solo 1 events.

If it's not leaking (maybe even if it is), definitely get it looked at.

Power Tran warranty!
My 07 doesn't burn anything between oil changes. Always used regular 5w30.

for an 07? that's too much.

Also, are you checking the oil when the engine is warm every time? You can have a pretty large variation between a cold and hot engine.

I burn, at most, a quart every 5k miles. I wouldn't say that I consistently drive my car hard, I certainly wait till it warms up, but I also can't say that it's babied either.

1 quart every thousand is way too high anyway, but it will only hurt oil consumption if you mash the gas when the car is cold.

I'd be more concerned about the integrity of the engine when mashing while cold vs oil consumption.

You have the option to try and bump up the hot viscosity. Try running a 5w40 or 10w40 and see if the consumption minimizes.

Some oils are kind of thin when hot. Mobil 1 is like this. Run their 0w30 or 5w30, and you need to keep a hawk's eye on the oil levels if you do any hard driving. An auto-x day will burn off nearly a quart. Move to a 0w40 or 5w40, and this pretty much doesn't happen. As well, switching to different brands and different formulations will give you different results. Not all 5w30s are the same, and you will notice different consumption levels with each.

Now, there is a chance that your engine has problems. If you are not heavy with your car, you most likely have a problem like broken rings or something. Generally, the heavy consumption is a byproduct of hard driving and running near redline for periods of time (auto racing). This is the only real way to get serious consumption on a perfectly good engine. Under normal/light driving, you shouldn't.

I say try a 10w40 and see if it changes. If you still have problems, bring it to the dealer. I'd also contact the dealer NOW and tell them what's going on. You can tell them you'll try a 10w40 and see how things go, or they may want you to bring in the car right away. You may need a new engine.

ive had to add 1/4 er so before, but nothing more. and thanks roadrunner for making me feel better, i feel dumb for checking my oil between runs ( like some over protective owner of a slow car ), but i guess it really is a good idea.

Well, during every gas fill up is a good practice. You can't exactly lose a massive amount, but yeah, keep an eye on it. If you don't it will bite you, and you'll be putting in a new engine. There are plenty of threads on Nasioc of people doing this on very new cars simply because they were ignorant.

i do drive my car pretty hard, so i guess that may be where some of it is going. I will try 10w40 on my next oil change and see what happens. i bought the extended warranty, so i still have quite a few miles before i have to worry much about the expense coming out of my pocket.

Bah, come back when you're a real man and measure your consumption in quarts per mile!


I burn about 1qt/1k. It seems that it's all going through the valvecover and crankcase breathers. Bumping up to Shell Rotella T 5w40 (which is VERY HEAVY for its grade), seems to have slowed it a good bit.
