I've been religiously adding my fuel purchases to fuelly.com and have noticed a definite improvement when I use premium fuel compared to regular unleaded. I notice a slight performance increase (this could be my imagination, I suppose, or the weight of the fuel assisting the pump?) and a measurable increase in MPG.
Has anyone else noticed this? Does anyone have fuel or fuel additive recommendations to increase MPG?
