It sucks having a Mach, having to use premium but oddly i seem to get better gas milage with the Mach than I do with the V6
Because you don't have to push it so hard to get up to speed

When I drive my Mirage I have to push that thing so hard so trucks and other vehicles won't run me over.

Because horsepower is a measure of efficiency, and higher hp is actually a better messurement of fuel economy, and even if u have to fire 2 more injectors than a V6 at higher lbs/hour...your engine has to turn less revolutions to maintain speed or accelerate...so overall you recieve better gas milage

Saying "it sucks having a mach 1" is a sin.
