Which Pickup Truck Has the Largest Fuel Tank?

With the price of oil remaining well beyond $100 per barrel, the American Automotive Association (AAA) reports the national gas price average is over $5 per gallon, nearly double that of July 2021 and an all-time high since AAA began collecting pricing data over two decades ago. Although the heat of wallets burning the backsides of pickup truck drivers seems to be getting hotter this summer, buyers will still seek out models equipped with the largest fuel tanks manufacturers can provide.

The size of pickup truck fuel tanks is a major purchasing factor for drivers that routinely tow boats, campers, and utility trailers. Yes, it costs more to fill up, but it means less time spent at the pump, which adds up commuting to work or driving to and from contracting jobs. For those wanting to pack as much fuel as possible into their tanks, 2022 pickup truck models are here to deliver outstanding results, with the top three presenting a fuel range exceeding 700 miles.

Pickup Truck + SUV Talk listed the 2022 Toyota Tundra as a truck with one of the largest fuel tanks. Toyota states that while the base model Tundra comes stock with a 22.5-gallon fuel tank, all Tundras optioned with the SR Convenience Package and the Limited, Platinum, 1794 Edition, and TRD Pro trim levels roll off the assembly line in San Antonio, Texas, with a 32.2-gallon fuel tank. While Toyota’s newly-designed, third-generation, full-size offering improves on many of the pickup truck’s features from the previous model, one thing it does leave behind is the optional 38-gallon fuel tank.

Nevertheless, the manufacturer’s all-new 389-horsepower i-FORCE 3.5L twin-turbo V6 delivers far better fuel mileage than the 5.7-liter V8 it replaces. According to figures from the U.S. Environmental Protection Agency (EPA), the 2022 model is rated at 23 mpg for two-wheel drive and 21 mpg for four-wheel drive pickup models, seven miles per gallon better than the 2021 Tundra, now giving drivers an estimated 740 miles per tank.

Ram Trucks explains that their base model 1500 will include a 26-gallon fuel tank, but buyers may spec a 33-gallon reservoir by visiting the options list. Yet, those seeking the shock-and-awe TRX model will enjoy the 33-gallon tank as standard.

Two-wheel drive 1500’s have an EPA-estimated fuel mileage of 23 mpg, and four-wheel drive models can push 22.5 mpg when teamed with the 305-horsepower 3.5 liter Pentastar V6, which matches the prior generation’s Hemi V8 0-60 time of 6.6 seconds, according to Pentastars.com.

Even though drivers will have to shake their heads when passersby ask if the truck has a Hemi, 2022 Ram 1500 buyers can expect to travel an impressive 759 miles between fill-ups.

2022 Ford F-150 – 36-gallon fuel tank

Most trim levels for Ford’s 14th generation F-150 will come from the factory with a 23-gallon fuel tank. If buyers opt for the Maximum Towing Package – available for all non-hybrid models, excluding the 122-inch wheelbase version – their new rig will boast an industry-leading 36-gallon fuel tank.

Ford announced its EPA-estimated fuel economy ratings at 22 mpg for two-wheel drive and 21.5 mpg for four-wheel drive configurations with its 3.5L EcoBoost V6. This will permit pickup truck drivers to stretch their legs on the highway as they will be able to cover a distance of 792 miles between fill-ups, or roughly Dallas, Texas, to Denver, Colorado.
