Just to ad my 2 cents.. this was also my concern.
The previous owner used Valvoline 10W30 in the A4... clutch slipped a lot. If you opened up the throttle while cruising the engine would eventually rev up and you'd go nowhere as the clutch slipped away. It also popped out of reverse.
I went with Mobil 1 10W40 motorcycle oil... no friction modifiers. No more clutch slip. My only issue is a lower oil pressure, which I questioned in another thread here. Now that I know there's an adjustment, and I now know where, I'm going to crank it up a touch.
The engine is quieter, and doesn't slip out of reverse now and also will speed up going forward when I open the throttle.
I have read about others with slipping clutches and popping out of reverse and then I read about the oil they use and I suspect this is why.
I also note here people whining about the cost of oil when you bought a sailboat. Spend thousands on a boat then cheap out on the oil. Duh.!!
