Hi Guys,
Newbie here, had a look for an answer but still undecided, recently bought a 2007 wrx with some mods such as sti turbo, bigger injectors and fuel pump. Have 120,000ks on the clock, due for my first oil change, subaru recommends 5w30 and i know the genuine stuff is Castrol Edge. I spoke to S&J and they recommended ULX110 10w30. If i was to go with Castrol Edge, what subaru recommends, id be more inclined to go with a 10w30 rather than a 5w30 as i think thats too thin. What do you guys run? Anyone tried ULX110?
Thanks in advance.
