I get asked many questions about oil so I thought a thread here for all oil related questions would be a good idea and build into a FAQ or reference point for others.
So, put your oil questions here but please give the following information if you would like a recommendation:
Make
Model
Year
Engine size/type
Any mods
Type of use (road/track)
Additional info (max oil temps, current oil used)
What do you want a recommendation for? Engine, Gearbox etc?
I hope this will help and become a useful thread
Regards
Guy

10w-40 Castrol would not be the best choice as it is a semi synthetic, these things really deserve a decent synthetic. If you plan plenty of hard use over the summer have a look at 10w-50, if its mainly cruising 5w-40 will be fine.
For the gearbox, diffs and transfer the Silkolene Syn5 75w-90.

Excellent mate thanks, I figured on using something like Silkolene Pro S for the engine?
