Across each of the 2008 Toyota Tundra’s trim levels, you’ll find the same gas tank with a fuel capacity of 26.4 gallons—regardless of the size of the pickup’s engine, the length of its bed, or whether its two-wheel or four-wheel drive.

Pulling up to the pump in a rugged pick-up truck, especially one that’s more than a decade old, can be a real pain in the wallet. That’s one reason it’s important that you know exactly how much gas it’s going to take to top off your tank.

How big is the gas tank on a 2008 Toyota Tundra?

While the gas tank size on many trucks depends on the size of the pick-up’s engine, or the length of its bed, the 2008 Toyota Tundra boasts the same size gas tank regardless of these factors.

That means that whether your Tundra is equipped with a 4.0-liter V6, a 4.7-liter V8, or a 5.7-liter V8 engine, it will always have a gas tank fuel capacity of 26.4 gallons. The same is true regarding whether the model is a crew cab or regular cab, two-wheel drive or four-wheel drive, or whether the truck’s bed is 5.6 feet, 6.6 feet, or 8.1 feet.

How to save on fuel costs in a Toyota Tundra

While all 2008 Tundra models might have the same gas tank fuel capacity, they don’t all have the same fuel economy rating. This means that you can easily save money on fuel costs by driving a Tundra with a better fuel economy rating. Let’s take a closer look at fuel economy details across the 2008 Tundra lineup:

Engine	Drivetrain	Combined (city/highway) gas mileage	Total range on a full tank
4.0-liter V6	2-wheel drive	17 mpg	448.8 miles
4.7-liter V8	2-wheel drive	15 mpg	396 miles
4.7-liter V8	4-wheel drive	15 mpg	396 miles
5.7-liter V8	2-wheel drive	16 mpg	422.4 miles
5.7-liter V8	4-wheel drive	14 mpg	369.6 miles

For the most cost-effective combination of features, opting for a Tundra equipped with two-wheel drive and a V-6 engine is your best bet. If you already own one of the Tundra models that guzzles gas, check out these tips to conserve gas and save money:

Keep up with maintenance. Your Tundra’s fuel economy can dip if you allow wear and tear on your system to build up.

Drive carefully. Ease up on the gas pedal and avoid harsh acceleration to keep your fuel consumption steady (and low).

Don’t idle. Letting your car run when you’re not driving wastes gas, so drive your car gently to warm it up on cold mornings, and shut it off if you’re going to be parked for a while.
