just bought some mobil1 0-40 fully synthetic oil for a change is this the right grade for my wrx 2.0 bugye 2001 or should i change it for 15-30 fully synthetic cheers for the help
You should have asked on here before you bought that oil!
Ideally you should be using something like a 10w/40 especially in the warmer weather, certainly no thinner than a 5w/40
ok im confused why would opie oils recommend 5-30 if its too thin thought they were ment to be the nutz with the oil situation
I thinks newage use /30 or /40 whichever you prefer subaru recommend /30.As far as i know if you have 0w oil its no thinner than say 5w or 10w its just more usable in very low temperatures which we dont have over here.

It's because 5w-30 is the standard choice for your car andyou'll find there are plenty of Scoobys that have run it without issues. A 5w-40 is also absolutely fine for your car. You'd only need to go for something like a 10w-50 if it's heavily modified. A lot of subaru owners/tuners think that the engine needs a really thick oil, but can never provide any reason why.
