Anyone who claims 30mpg with the SS is out of their fking rocker. Straight up BS.
At best I've had roughly 24mpg on cruise control with my automatic cruising at around 70mpg at 2k rpm.
Cold air intake, long tube headers and a custom dyno tune.
Tested different speeds for well over 1,500 miles from TX to California.
It doesn't get any better than maybe 25mpg.
Who buys an SS for MPG anyways? That's like saying I'm trying to watch how many calories are in this homemade bacon cheeseburger.
