I've always liked chevron gas because it has techroline, which is one
of the best fuel detergents. But I've noticed lately that when I buy
Chevron my 2009 PT seems to get about 2 - 3 mpg worse gas mileage. My
other typical fill up is some "FastGas" type place. This change has
happened often enough that I'm pretty sure it's not completely my
imagination. Anyone else noticed such a change from one brand to
another? On the FastGas I usually get 24.5 on my typical driving
cycle, 70% commute, on the Chevron it drops down to about 22.

Brands have different additives, but nothing that should affect
gas mileage given equal octane. Most likely it's just plecebo effect.

Amount of alcohol added, seasonal blend formulations and accuracy of the
blend, quality of gas as far as moisture/water due to condensation that
collects in the tanks, particularly during th winter can be a factor.

10% ethanol out here and that's not a seasonal thing.

local techs recommend a small amount of amsoil 2 stroke in your gas tank but
a very small amount, about 1 ounce per 10 gallons i think but i am checking
on that now.

Are these by any chance techs who make a large profit on replacing
catalytic converters?
