Take it to a dealer, explain to them that it shouldnt lose any oil. Tell them to find the leak or do a compression test, but you want it it fixed under warranty. (if you are still under warranty)
For that kind of money, it danged well better be a Cummins diesel!

As long as there are no leaks and the amount of loss stays fairly consistent I wouldn't worry about it. If it gets worse I'd have a leak down test, compression test, and maybe an oil analysis. My wife's car goes through 1 qt every 3k miles. It's done that for about the last 50k miles. My last car had two cracked pistons and I finally had the engine rebuilt with it went through 1/2 qt in 10 miles.

I would tend to agree, however the reality is some cars do tend to use some oil. Talk to almost any VW driver, for example. Some use a quart in less than a thousand miles, and the dealers insist its normal.

This is my take on the subject.

This ^^^.

It is highly unusual for a modern engine to consume oil at this pace. It may or may not be a sign that a major failure is in the offing.

I would bring it to the dealers attention, and make sure it is documented. When things go south, either before or after the warranty expires, your concerns wil be well documented and the dealer will be prepared to absorb the repair bill--which could be quite extensive. If the dealer shrugs his shoulders, ask to have a conference with the regional manager such that you have his word that 'the oil consumption issue is normal' for this vehicle--and when it breaks down, you'll have further evidence that you asked about it well before the failure, and well before the warranty expired.

"1 qt every 1k miles is acceptable"

really? so at a 5kmile oil change, there would be no oil left?

I don't like it either, and in fact I've never owned a car that used any measureable amount in that period of time (I've owned a few that leaked though...).

But like I said, call a VW dealer and complain about that kind of oil use. They'll claim its normal!

Read any manual, ask any dealer, ask any mechanic. You should be checking the oil between changes. If it's low fill it up. Every manual I've read says to check every time you get gas.

a quart every 5000 miles is normal on new engines. there is nothing to worry about until the oil loss gets down around a quart every 1000 miles or less. as indicated engines are designed to lose a little oil over time. there is always a little oil loss through the valve guides, out the rear main seal, and a little always gets past the rings and gets burned off in the combustion chamber. what i would do is keep an eye on the oil level, and when it gets a quart low, change the oil and filter.

by the way, if you want a real worry about nothing regarding oil, the old studebaker engines used to lose a quart of oil about every 1200 miles when new. like the yugo, studebakers came from the factory with an oil leak as standard equipment.
