Recently took a 762 mile trip ( oddly that's the exact mileage, both times when I filled up , the tenths position was 0). I used 28.07 gallons of gas. Average mpg on the round trip is 27.14 mpg .
the temp was in the high 80's, low 90's so A/C was running 85% of the trip. I was running a steady 70 mph( measured by my GPS on phone) I would have to go faster at times to get around traffic, my top speed on my scangauge was 78 mph.
Gas used was 87 octane, 10% ethanol.
I was pretty happy, since the EPA EST on the truck is 23 highway.
Cost per mile for fuel worked out to 9.55 cents.
Again my mods so you don't have to reread thread-
- 40% tonneau cover,
- lowered 3.5 rear, 2.5 front.
- 42 PSI in tires.
It does have running boards, or tube steps. I read where they may help a little, it has aluminum rims which maybe a little lighter than stock. Other than that it's completely stock.
If I lowered speed to 65 mph and had cool weather , it's no doubt in my mine this truck could touch 30 mpg.
