I know this has been asked many times but I picked up some castrol edge fully synthetic 5w-40 from costcos yesterday as my service light came on it says it's for Vw and is 502 and 505 spec, I've serviced it before but can't remember if I used this or 5w-30
is the 5w-30 the one to go for ? Car is jack up with oil drained and filter off ! Do I need to shoot to halfrauds and get ripped off ??
Thanks neal
