In my S3's manual, it says to check oil once the car is warmed up? Is this right? Im only asking because with all my other cars ive always checked it about 5 mins after the engine or before i go anywhere in it so that all the oil is in the sump (which i assumed would give me a proper reading on the dipstick)
Also which oil should i put in it? Is it best just to go to the dealers and buy the oil from them?
With my Astra GSI Turbo if i used the specified long life oil the car used to drink it and most people on the forum recommended using the thicker semi synth oil and doing more regular changes, is it the same with the S3?
