159 V6 Q4


Could anyone advise on the preferred petrol to use on the V6. I am presuming premium or will any quality suffice?

Re: Petrol

Does the handbook specify what Octane is required? ie 95 regular or 97 super?

Personally I try to buy from a busy petrol station, to ensure fresh petrol and from either Shell, Esso, BP or Texaco. I never use supermarket gas. Petrols do deteriorate in the large tanks under fuel stations, so using a busy forecourt is a worthwhile exercise. Shell Optimax used to lose it's octane rating in the tanks very quickly.

For some reason, I don't know if this is psychological, my little Twinny (remapped) seems to spin best on Texaco 95 octane.

Re: Petrol

Shell fuel is usually the best. I use V-power as I find it actually improves my engine. Plus its proven to clean the engine.

Avoid Esso and the Supermarket cheap crap.

You car is designed to run on 95 octane. You may not even notice a difference between 95 and 98.
