Correct Oil?
 

Hi Everyone.....
Can someone tell me the correct oil for the best results for a Wrx 2003 prodrive.
Ive been told use either 10w40 semi......Or....10w60 Castrol Edge Fully.
Can someone advise what oil to use or something different...
Thanks :D

had the same problem when i first owned a scooby and was recommended to use 10-40 semi only on my old wrx and also now on my sti by other members and also by the garage i use

Once run in I'd only use fully synthetic, high ester oil.

Not too thin, forget the 0- types, use 10-40 or so.

Dont go 10w-60, too thick when hot. Think high blood pressure. Depending on use 5w-40, 10w-40 or 10w-50 synthetic.

Cheers

Guy
