Smoking heavily

I would imagine it makes little difference when checked hot or cold, however my dealer told me to let the car run to (near) optimal temp...i.e. around 70 degrees oil temp and then let it rest by switching ignition off for 2-3 minutes. Then check oil level after this. Been doing this and it is fine so far...no oil usage.

Without wishing to hijack the thread, what is the correct way to check your oil level?

The handbook is a little vague (as was Audi Customer Services when I phoned them today)...

For arguments sake, what temperature should the oil be at when you check the level?

Viscosity is obviously a function of temperature....

Check it when its hot, oil temp around 80-95.

audijohn,

Thats weird because when I check mine cold its way down the dipstick...well below MIN.

But when I check it warmed up (i.e., after the limit to 7000rpm warning goes out), its in the acceptable range....

Anyone else observe this behaviour?

SR71, thats how it will be. When oil gets hot it expands and hence the level rises, this why you should not check it when its cold as the additional expansion could cause it to rise too much and be burnt off. You often see this happen at track days.
