hi all, ive been looking through the threads trying to find out whats best for my astra, but everyone that has asked advice has got 1.6 or 1.8s. now mine is the 2.2 and ive heard 3 different grades of oil can be used.
ive been on the castrol website and this is what it recommends . . .
the cars only done 45k if this changes owt. also is there any difference between 75w-80 and 75w-85 gearbox oils? opieoils has it all on 1page so is it ok to use either?
