Hi All:

___GoNavy, you have been doing your homework! Nice job …

___The Acura MDX (EPA rated at 17/23 on its recommended 91 Octane) was first driven beyond 30 mpg over a tank using Regular Unleaded. Is anyone else starting to get tired of the Premium vs. Regular threads even if the car/truck/SUV asks for Premium? It is the driver, not the gasoline unless said gasoline was bad in the first place. If you are pushing your hybrid into the realm where Premium is needed to reduce knock/advance pull back, you sure as hell aren’t receiving anything in the fuel economy department and the question would be complete waste of everybody’s time.

___As for all this Premium/Regular stuff, if you want every last bleeding ounce of performance out of your car/truck/hybrid, your FE is going to suck. If you want all the FE your hybrid/non-hybrid can muster, drive it for FE. Filling it for FE is non-sense unless you have a choice between non-E10 and E10 at the same station for the same price.

___Good Luck
