I’m a 5 under kinda guy. Pedal to the floor, max speed, then back down 5 under max. Haha

Then recently at 10-15 mph I totaled my wife escalade.
Now insurance concerns has me doing what the signs say about 95% of the time.

My hummer, top speed didn’t seem to affect mpg. Just how fast I accelerate. Even adding my turbo- accelerator to the floor until cruising speed my mpg stayed the same. Then I tried accelerating at the same 0-60 time as before turbo and gained 1-1.5 mpg.
