Hi,
Can anyone tell me what type/grade of engine oil I should be using for my MY06 (Hawkeye) Impreza WRX STi with PPP please? I've looked in the manual and can't find it. All I can find is different W ratings depending on what climate you're in :-/

Cheers

Hi

I would use a 5w-40 synthetic and you will find those through the link below.

5w-40, 5w-40 oil, 5w40, 5w/40

Out of those, the best ones are the Silkolene Pro S, Millers CFS, Motul 300V, Redline and Gulf Competition. The Motul 8100 X-Cess, Gulf Formula G, Fuchs Supersyn and Mobil Synt S are good, cheaper alternatives.

Cheers

how about we have a thread in the technical topics archive that lists all scoobies and what oils are recommended,that way its easier and quicker for people to find out what they want to know.
im sure oilman could do alist easily enough?

Yes, I probably could do that for all the standard cars but it will have to be a fairly basic list as there are so many available. It's probably better to just ask us for each car.

Thanks for the advice. When you say synthetic I'm assuming you mean fully synthetic, not semi?

I'd go for a full synthetic

I asked this question at extreme motor sport in Whitburn a few days ago the recomended 15/40 miller oil and these guys work on Subaru/Mitsubishi all the time if that helps I drive a wrx with a few mods turbo etc

15w/40 oil in cold weather could be a disaster for an Impreza. It takes oil ages at that grade to get warm and starting the car on a cold morning day after day is bound to cause issues. 5w/40 is a far safer option especially this time of the year.

The 15w-40 is also most likely to the be the bottom of the range oil, generally just mineral multigrades. Millers do some great oils (CFS range) but 15w-40 mineral I would not put near a impreza or evo.
