If you go to the extreme end of low octane as in some countries, then such fuel does the engine no good at all. By stretching the implication of this, one can probably deduce that higher octane is better, especially if you drive hard such that the anti-knock control mechanism becomes very active. I find Shell Optimax very good for the engine. I think it runs smoother. > The dealer just had to replace the turbo unit under warranty with > 40,000 miles. This is a very low mileage anyway. Probably not related to fuel type.
