Hi guys I was wondering if anyone could shed some light on my situation. I commute 150 miles on Friday to get home from work, and then the same when I go back again on Sunday. I bought an S3 a couple of months ago and it has been fine but all of a sudden the low oil light came on, I topped it up with 1/2 litre and within 1 150 mile journey the light came back on again, so again I've put 1/2 a litre in, and now after the 3rd trip the light has come on for a third time. There are no oil leaks, no loss of power, and it isn't smoking at all. What can be at fault?
