Owner reviews for engine oil
Had it on all my bikes great oil. Cheaper alternative will be Castrol power one ultimate.
This is amazing . I have it in my 200 ns and it feels so smooth. There is 300v too but i never tried it . 7100 is best engine oil beside petronas if you can locate it anywhere
The Motul 7100 20W50 is a good choice.
You can also try changing your oil to M1 15w50 full synthetic that helped me with my cold start rattling issues and the engine seems to run smoother along with the vanos idle clacking noises going away.
Here I am just dumping in Amsoil 5W-50 SSO because all I care about is shear wear protection and something content with high temp operation. 20,000 miles and not even a single psi drop in compression the whole time, don't even premix.
I think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.
As to which one, the two that are reported to induce the *least* consumption are Liqui Moly Leichtlauf, and Fuchs Titan Super Syn.
something you might consider is switching to Shell Rotella T6 5w-40.
you can find many testimonies to the benefits of using T6.
I have a 98 TDI with 269k and I had an 06 TDI with 131k. I have dumped the unfiltered engine oil after each change into the tanks of both cars since I've had them (Beetle, 98, got at 230,880 miles). They burn fine.
