I don't use my car a great deal and when I do it's driven frugally...unless the gf isn't in the car . Changed the oil in January for some expensive synthetic stuff and this morning I had 3 people in the car, driving up a hill in 4th gear (50mph speed limit road) and the oil light popped on saying it was low. I waited to get to the flat, shut it off and waited a bit in case it was just the hill. Slowly drove to a garage to get some oil as it didn't make any difference.
Topped it up, checked it, topped it up a bit more, dunked even more in and it still wasn't making a difference. Ended up putting 2.5L in (fully synth) for it to get up the mark. The dipstick holder isn't broken, the car isn't really stressed a great deal and always warmed up/cooled down. I just think 2.5L is a bit much. Hopefully the level is showing the correct amount now as I know too much oil is bad. Do these cars use THAT much in a few months? I know other Audis need topping up every 1k miles or so, but haven't heard this with the 8L.
I was going to change the oil in a few weeks as I've just clicked over 5k miles since it was changed.
