I've only had mine a few weeks but the previous owner on my A4 said that he'd have to fill up around every three months. Mine's a 3.0 and luurves to guzzle anything though. Sorry that's probably not much help at all, but in short you're not the only one that has the oil burnt away and the dealer reckons this is normal with mine too
I'll definately have to keep a closer eye on it, I've tried coaching the wife in how to fill the tank with petrol, she has as much respect for that as she does for the game of rugby (zero) So I guess I will have the same problem trying to get here to check the oil level in HER CAR');]It only seems to be mine when the petrol light is on and the thing is covered salt grit and crud. Thanks for the info.
"Turbo diesels don't like having the oil at max. as more gets drawn into the turbo. Handbook says to keep it at middle between the marks
In the Audi Service book it divides the dipstick into A, B, and C
"When the engine is working hard......the oil should preferably be kept in Area A (but not above)
Area B - "it is sufficent if the oil level is somewhere in this area.
Area C - "oil must be topped up"
Maybe, if you are talking from experience, the pd unit prefers to have the oil inbetween the min and the max.
i can see why it would be harmful to go over the max, but i think i will keep my oil in the A area......mind you it always uses some and will go down to Area B........then i will top up. 160k miles and still going strong.
