How to Improve the Fuel Economy of a 2005 Ford 5.4 L Triton

The 2005 Ford 5.4-liter Triton is the engine model used in many of Ford's truck models, such as the F-150. Improving fuel economy can be done in a large variety of ways in the everyday use of your vehicle. Fuel economy can change from little things such as your driving habits to larger problems that require maintenance. By keeping up with your vehicle's maintenance and following simple guidelines, you can almost certainly improve your truck's fuel economy.

• 1

  Drive more efficiently and avoid aggressive driving. Speeding, rapid acceleration and rapid braking all reduce fuel economy and can reduce gas mileage by 33 percent at highway speeds and 5 percent in the city. Following the speed limit is one big way to improve fuel economy. Most vehicles see a reduced gas mileage for any speeds above 60 mph.

• 2

  Remove any extra weight from your vehicle. Every extra 100 pounds carried in your vehicle can cause it to reduce your miles per gallon as much as 2 percent.

• 3

  Avoid idling. This will cause your vehicle to consume fuel while you go nowhere.

• 4

  Use cruise control and overdrive gears. Cruise control will allow your vehicle to maintain a constant speed. Overdrive gears will allow the 5.4-liter Triton engine speed to be reduced and reduce engine wear.

• 5

  Avoid using the air conditioner. This puts extra strain on the engine and increases fuel consumption.

• 6

  Inflate your tires to the dealer-specified levels. Uninflated tires can increase resistance on the road and decrease fuel economy.

• 7

  Keep your engine and other maintenance up to date. Making sure spark plugs, fuel ratio, spark timing, oil and filters are in good working order can help improve fuel economy. Addressing large maintenance issues such as the oxygen sensor can improve mileage as much as 40 percent, according to FuelEconomy.gov, which also advises that using the recommended grade of motor oil can increase mileage 1 to 2 percent. Also use the recommended fuel type.

• 8

  Combine errands so you can make trips together instead of starting the engine "cold" for every trip, which can use double the amount of fuel, according to FuelEconomy.gov.

• 9

  Car pooling can be a good way to improve fuel economy because you won't be using your vehicle for every commute.

• 10

  Don't drive with the windows down or luggage piled up on the top of the vehicle or high in the truck bed as this will increase wind resistance, lowering fuel economy.

• 11

  Add a hard top bed cover, also called a tonneau, to the bed of the truck. This will improve aerodynamics and boost fuel economy.

• 12

  Make improvements to your vehicle that offer better fuel economy, such as a more efficient exhaust or air intake.
