They get less economy with Sunoco 94 compared to the other company's premiums, such as Esso or Shell. It's the ethanol in Sunoco which causes the lower fuel economy.quote:

Yup...not only that, but I can tell the performance (response) difference when a certain Sunoco is BS'ing the grade and has mixed the 94 with others. There are certain Sunoco's I won't fill up at and I avoid the one's with mixed pumps.
Over what do the guys get less fuel economy? Sunoco's 92?
I find my car has the best throttle response with Shell's Optimax 91 octane. Although Esso 91 is still pretty good too. For some reason my car just doesn't seem to like Sunoco 94 too much.
