Heads-up! You won’t find a gas cap behind that fuel tank door. Newer Explorers don’t have one, so don’t be alarmed if you don’t find one.
Those aren’t the only changes that Ford has made to the Explorer’s fuel tank. In 2011, the Explorer’s fuel tank dropped in size from 22.5 gallons to 18.6. It was shrunk again in 2020 from 18.6 gallons to the current 18-gallon reservoir.
The good news is that the Explorer’s fuel economy has been steadily improving, reducing the need to hold a big reserve of fuel. The 2016 Explorer achieved a combined fuel economy rating between 15 and 22 mpg. That’s better than the 2010 version’s combined mpg of 15 to 17 but lags behind current models, which achieve a combined rating of between 19 and 24 miles per gallon.
