2007 A6 BURNING OIL
I have 60000 miles on my A6 and she burns a quart of oil every 1000 miles or so.
Anyone have this issue? My past Audis never had this problem...

you sure about a full quart? My experience in the last year or so is about half a quart every 1000 miles. Audi/Porche tech in Columbus OH told me it's normal with the 3.2V6 and would refill 1/4 quart every 500 miles or so.
My 1.8T A4 never had that problem though.

Mine burns up to a quart every 5k miles. My old '07 A4 2.0T didn't burn a drop of oil and neither does my current E46. My sister bought a FWD CVT 2.0T A4 last year and she tells me theirs burns about a quart every 2000 miles or so.

With today's new engines, you shouldn't be burning any oil. There are only two ways oil could escape your engine. One obvious reason is that you have a bad seal somewhere (filter, oil pan gasket, etc)and you're leaking oil. This should be easy to detect since you'll be leaving a trail of oil on the ground. The other possible reason is that you have a set of bad piston seals and substantial amount of oil is being lost in the combustion chamber. In this case, you should notice blueish smoke coming out of your exhaust.
My advice, especially if your car is under warranty, is to have your dealer perform an engine compression test. They will remove your spark plug and screw in a gauge that measures the psi of your engine during the compression cycle of each cylinder. Traditionally you compression should be 170-200+ psi. If one of the pistons is allowing oil to be passed through the combustion chamber, the piston seals are bad and the gauge would indicate a lot lower value. Also, if you're actually "burning" oil, your spark plug should be fouled with heavy oil coating. You should also notice a loss in power and mpg.
I have never heard of any new engines losing oil as being normal. I'd question any dealer that tells you otherwise.

If you were burning 1 quart every 1000 miles it is quite possible you wouldnt see ANY blue smoke out the exhaust. I have had a car that burned oil at this rate and never saw any blue smoke. Also at 60k miles there isnt anything a dealer will do for you, besides at 1 quart every 1k miles every dealer I know of will say it is NORMAL even if car is new. Dont waste your time, just dont let it drop enough to damage engine.

I dont understand the logic in how burning oil can be normal. My A6 burns oil at about a quart every 5000 miles, my cousin passat does the same, along with my mothers bmw 328. My A6 has 65k, passat has 110k, but the bmw has 11k. How cant this be "normal", can anyone explain please.

If an engine is "burning" 1Qt of oil every 1K miles, it's got serious issues. I make that statement because oil doesn't just burn up in the combustion chamber. At that rate, you will foul up your plugs in a hurry and a lot of oil will enter your exhaust system, eventually plugging up the catalytic converter. I don't see how you will pass the smog test if your engine is burning that much oil.
