6 cyl.
No one really worried about MPG back then, but I figure it was in the single digits to low teens as a v-8
A 1967 Shelby Mustang G.T. 500 gets 9-12 mpg
20 mpg going 55 mph
I get roughly 14-16 MPG.
Depends on what Mustang, normally 19 on the street and about 30 on the highway.
I get about 16 MPG on mine but I do a lot of city driving.
13 mpg in city & 15 mpg on HWY
