I was wondering what is considered normal, to see if I have any issues. I usually top off a quartz about ~1600km. Also what oil should I be using? I have read anywhere from 5W-30 to 5W-50. I currently use 5W-40.

 

that's not normal.
i don't have to top off my oil at all between oil changes.

 

Depending how far you go between oil changes it is quite normal to top up between. In my 4.2 S4 I usually have to top up a litre between changes and those happen at around the 8K mark.

Hope that helps.

 

i change my oil every 7k.
the only times i had to top off were when i had leaks.
once was a gasket, once was the little breather hose.

 

I agree with KF. I change my oil every 5K and never had to top up. As a matter of fact, minimal loss of oil when i drain it out. Now, if you are driving the car hard, it wouldnt be strange that you would have to top up the oil.

My buddy and I beat the crap out of a 2003 Porsche Turbo when we had it for 2 weeks and we were topping up oil in it daily...lol.

As for which oil, I use the same one as dealerships. Castrol Syntec 5-40.

 

ya it depends on how you drive... i took my car out once on an empty parking lot with fresh snow to do some donuts. had it on 1st gear for a while, so i had to top oil afterwards

 

Thanks for the info guys. Appreciate it. I drive it pretty hard... lol
