How big is the gas tank on a gx550?

The gas tank size of the GX550 is 23.0 gallons or 87 liters. This full-size luxury SUV from Lexus has a sizable fuel tank capacity to support its powerful engine and accommodate long-distance driving.


Detailed Overview of the GX550 Gas Tank


The Lexus GX550 is a large, three-row SUV that is known for its off-road capabilities and premium interior. One of the key specifications of this vehicle is its fuel tank capacity, which plays a crucial role in determining its driving range and refueling needs.


According to the information available on the Lexus website and in various automotive reviews, the GX550 has a gas tank size of 23.0 gallons or 87 liters. This sizable fuel tank allows the GX550 to have a longer driving range compared to smaller SUVs or crossovers, making it well-suited for long-distance road trips or towing heavy loads.


The large gas tank size is particularly important for the GX550 given its powerful 4.6-liter V8 engine, which delivers 301 horsepower and 329 lb-ft of torque. This engine, combined with the vehicle's substantial size and weight, requires more fuel to operate, making the 23.0-gallon tank a necessary feature.


Fuel Efficiency and Driving Range


While the GX550's gas tank size is impressive, its fuel efficiency is relatively modest compared to some of its competitors. The EPA-estimated fuel economy for the GX550 is 16 mpg in the city and 19 mpg on the highway. This translates to a combined fuel economy of 17 mpg.


With a 23.0-gallon fuel tank and a combined fuel economy of 17 mpg, the GX550 has an estimated driving range of around 391 miles on a full tank of gas. This range can vary depending on driving conditions, load, and other factors, but it provides a general idea of the GX550's long-distance capabilities.


Refueling the GX550



  • The GX550's large gas tank size means that it will require more frequent refueling compared to smaller SUVs or crossovers.

  • Owners can expect to fill up the tank approximately every 300-400 miles, depending on their driving habits and conditions.

  • The GX550's fuel tank is located on the driver's side of the vehicle, making it easy to access at most gas stations.

  • It's important for GX550 owners to monitor their fuel levels and plan their refueling stops accordingly, especially when traveling long distances or towing heavy loads.


In summary, the Lexus GX550 has a sizable gas tank capacity of 23.0 gallons or 87 liters, which supports its powerful engine and long-distance driving capabilities. While the fuel efficiency is not the best in its class, the large tank size provides a respectable driving range for this full-size luxury SUV.
