The Ford F-150 EcoBoost 4X4 now comes standard with a 36 gallon tank, combined with 21mpg on the highway, you'll be going a mighty long way before you need to look for gas, almost the entire length of California, for instance. No need for one of those aftermarket fuel tanks in the bed, this truck will get you there and back, up to 756 miles.
Ford says the EcoBoost V6 has become a best seller:
The F-150’s 3.5-liter EcoBoost engine, which debuted earlier this year, has quickly become the industry’s top-selling V6 engine in full-sized pickups. The F-150 EcoBoost outsells all competitive V6 full-sized trucks – Chevrolet Silverado, GMC Sierra, Toyota Tundra and Dodge Ram – combined.
Yes, the fill up is a big one, but once done, you're good to go. No worrying about gas while you're on the job, plan your fuel stops to fit your schedule. Nice touch.
