Someone mentioned in another thead that when you switch abck to higher octane the engine readjusts to teh correct timing ?
Also, in the same thread i beleev Fbod or someone mentioned that although using 93 octane costs more at teh pump, the cost is offset by getting the correct mileage by using the 'recommended fuel for best performance' 9as it says in the manual)
