As I have just bought my JDM Sti Wagon, I am guessing that it is V power all the way? Am I right that BP ultimate and Texaco High Octane are not as good?

 

Best fuel is V-Power very closely followed by Tesco 99. I would use either of these in yours. Most imports benefit from mapping to our considerably watered down fuels, obviously not water, just lower Ron!! UK spec cars can run 95 Ron, IMO they benefit from 'Super' i.e. 97 Ron. The one thing I will say is that you should never never use BP Ultimate, its not good for Scoobs and can cause det and you really don't want that.
