Owner reviews for engine oil

I have amsoil 20/50 in the crank, amsoil primary, and amsoil tranny. It’s the bees knees

I heard you can throw 20W-50 (Synthetic, specifically V-Twin Mobil One brand) in all three holes and have no issues.

Rotella 15w40 for mine. Never an issue and good oil reports for several hundred thousand miles.

Have been using Motul 5w30 for many years now...

Rotella T6 has been good to me.

My rotary expert in north Texas recommended that I use 10-30 conventional oil. I personally prefer Castrol GTX

I see all these people shit talking the oil, but they haven't actually used it. I've used it, and it's great. I put it in one car (pontiac) with over 70k miles and it ran way better than with normal full synthetic. I got a 02 explorer with almost 200k miles, it was idling rough as hell. I thought it would need a tune up, spark plugs, ignition coils, oil change and air filter. One bottle later, started it up and it was almost silent.

I use Idemitsu Wankel Racing Oil. 10w30, I think.

2012 3.0tfsi turned out to be a mild hybrid as it burns 1l/5k km.

Hmm... I just took the car in for its MoT and although it passed, they noticed that the exhaust was smoky and that oil level had been overfilled. The oil was last changed at the car's 40,000 mile service by the same VW dealer and on the invoice they've listed 9 litres of oil.
