I was just wondering what petrol you guys use for your wrx,i have a 93.I was using shell optimax but all the shell garages have dissapeared round hear so iv started using bp's new superunleaded petrol ultimate ?

 

I put some of that in the other day.....i usually use optimax. only had my scoob a couple of days and av filled the tank up twice!

 

Both of you are risking serious trouble running Japanese market cars on Super Unleaded alone. You need octane booster to bring UK spec SUL up to what the ECU is expecting you to use. There's loads been written on this subject - use the Search Luke.
