The dealer did a change to test for oil consumption by swapping in Agip Synthetic PC 5W-40 and told me to return in 1000 miles to check the level. Yesterday I was driving very aggressively (downshifting, 140mph burst on desolate road, redline through the gears) for ~ 80 miles. Anyway, it has been 300 miles since the change and my oil level was at the very minimum on the dipstick. This is usually 1/2-1 qt. low. My sytstem supposedly holds 12-13 qts. of oil in an Audi 4.2V8. Could this have caused any undue or excessive wear driving this way w/ the oil level low? No oil light came on. I am concerned.
