I fill it up just under the recommended amount. Then keep checking the dipstick as I finish topping it up to get it to the top of the marker. But no higher (not an A4).Apologies for high-jacking but i've got to change the oil in my Audi A4. It states that it takes 3.8L, could I put in 4L and get away with it?
You need to get it between the min and max marker on the dipstick. Too little is obviously bad. But so it too much.
