Changing oil but what to go for....

[cornish6544]

So changing the oil in my impreza next week and just want to check I'm using the best possible solution for my car. It is a 94 classic wrx now producing 312bhp. I was going to go for Shell oil but i would like to know exactly what i should go for now its been mapped. The engine has not been rebuilt to my knowledge however i have had the cam belt checked and thats fine and its now done just over one hundred thousand miles. 

 

Any advice would be great

I personally use Millers 10w 40... quite a popular choice and very good quality.

Check the ask Opie Oils thread in the relevant section on the forum..lots of good model-specific advice on there from people who know their stuff, oil wise [emoji106]

I have the same car and mine is running at 322bhp and I use Shell 5-40 fully and a k&n oil filter and have had no problems and the engine is silent
