I am have used Mobil One 0w 40 since my 1st oil change at 10k and have had no issues what so ever. infact the engine ran quieter, rev'd quicker, and pulled harder.
I have just gone over 15k and time to do a new oil change.
I was at the stealer and they said they would put in Quantum 5w30 if i was to have a service with them and that 0w40 is no good...
Im sure that the Mobil One stuff is VW approved etc, but im ALSO sure that quantum 5w30 is not VW 502.00 or 505.00 certified. therefore you should go with Mobil1 0w40 at a minimum to meet VW oil specifications.
any way, what oil do you guys run?
and as its coming up to winter should i start looking at a different type of oil ?
