High gas prices have hit motorists with an increasing transportation toll every time they fill up. The cost is especially high for full-sized SUV and truck drivers, as those vehicles tend to be the thirstiest and to have the biggest tanks.

At today’s national average price of $4.80 a gallon for regular gasoline, there are 10 models from CR’s tests that cost over $100 to fill their tanks from empty. These vehicles all have a large tank capable of holding 24 to 28 gallons, and their fuel economy, based on CR’s tests, spans from 14 to 17 mpg overall, the lowest among our tested vehicles. These drivers are likely to be feeling the pinch. 

Two models we’re testing now could soon join this group: 
• The Toyota Tundra, with a 32.2-gallon tank, would cost $155 to fill up. 
• The Jeep Wagoneer, with its 26.5-gallon tank, likewise belongs in the over-$100 club, costing $127 to fill up.

These are extreme examples, but many drivers are seeking relief now. 

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.
