VEHICLES THAT COST THE MOST TO GAS UP

Several vehicles tested by CR still cost almost $100 for a full tank, despite gas prices coming down. See our tips and advice for conserving gas and saving at the pump.

Gas prices may be settling down from the high figures seen at pumps in 2022, but it can still cost quite a bit to fill up larger vehicles. And the pain is doubled when the fuel economy is low. We see this play out with full-sized SUVs and trucks, because those vehicles tend to be the thirstiest and to have the biggest tanks. To understand what the costs are like today, we pulled together data from our tests and database, combined with national gas prices via AAA.

With the current national average price of $3.38 a gallon for regular gasoline, several models from CR’s tests cost almost $100 to fill their tanks from empty. These vehicles all have a large tank capable of holding 28 to 32 gallons, and their fuel economy, based on CR’s tests, spans from 16 to 17 mpg overall. Even with gas prices coming down, drivers of these full-sized models are still feeling the pinch. 

A full-sized SUV currently being tested will cost less than these vehicles due to its smaller tank size: 

• The Toyota Sequoia, with a 22.5-gallon tank, would cost $76 to fill up. 

These extreme examples show what the maximum costs for fill-ups can be. But no matter what you drive, there are ways to improve fuel economy and save at the pump.

Key Gas-Saving Tips

• Gas cards may be tempting for the discounts, but a regular cash-back card might save you more.

• Shop around for the best deal at the pump. Using an app like GasBuddy can save you money.

• You also can find lower prices if you buy discounted gas at Costco, Sam’s Club, or BJ’s Warehouse.

• Obey speed limits and drive smoothly. This technique can make a measurable difference in fuel economy for many vehicles.
