What oil should I use in my 2002 Mk4 GTi 20V Turbo? Cheers.
I have tried searching by the way, but I'm confused at all the different information I'm finding. The book says one thing and here it says that's old obsolete oil. I basically want to know the Viscosity I should use. I usually use Castrol, so if that's fine with a particular viscosity, then that'll be what I may go for.
