I've been doing a lot of searching but I'm still not sure which oil would be best for my girlfriend's 07 gti.
As it is, I'm leaning towards either Mobil 1 0w 40 or rotella t6. I was going to go with the Mobil but some have said that's a poor choice for this engine... But I'm not sure why.
I've used t6 in my b5 s4 for awhile but I'm not sure that'd be the best for winter... Especially since my gf doesn't give the car any warm up time in the mornings.
Suggestions?
Thanks in advance!
