Increase Your Fuel Economy
As fuel costs fluctuate and concerns about the environment increase, it’s helpful to be familiar with all the ways proper maintenance can help you save fuel.
Using the Right Oil
You can improve your gas mileage by up to 2% by using the manufacturer's recommended grade of motor oil.* Your recommended grade can be found in your Owner Guide, but it can vary depending on your driving conditions. Our experts have a full line of Motorcraft® oil and filter products on hand and will use the correct grade for your vehicle every time you come in for an oil change.
Keeping your Tires Properly Inflated
Underinflated tires are less safe, wear out faster and waste fuel, causing drivers to lose as many as 2 million gallons of gas per day. Keeping your tires inflated to the proper level can help improve your gas mileage by around 3%.* The operating vehicle tire inflation pressure that Ford Motor Company certifies and recommends for normal use is found on a Certification Decal or Tire Decal, usually located on the driver's door or door pillar, or the glove box. (Tire pressure information does NOT appear in the Owner Guide, as the government requires it to be permanently affixed to the vehicle.) Make sure not to exceed that number, though, because overinflated tires can be just as bad.
Keeping Your Engine Tuned
Fixing a car that is noticeably out of tune or has failed an emissions test can improve gas mileage by an average of 4%.* But here's the real bonus - if our experts find a malfunctioning oxygen sensor, replacing it can improve your mileage by as much as 40%.*
Other Regular Maintenance
Wheel alignments, shock and strut inspections, and replacing worn fuel filters or spark plugs can all help optimize your fuel economy too. Together, all these vehicle maintenance operations can improve your mileage by up to 25%.*
Drive To Maximize Your Fuel Economy
Making lots of short trips means you're driving with your engine cold. And that uses more fuel than making one long trip with an engine that's warmed up. Try combining your short trips around town as much as possible to optimize your fuel economy.
Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than just gas money.
Observe the Speed Limit
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 100 kph.
Remove Excess Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds or 45.5 kilograms in your vehicle could reduce your miles per gallon (mpg) or kilometers per liter by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
Avoid Excessive Idling
Idling reduces average fuel economy. Cars with larger engines typically waste more gas at idle than do cars with smaller engines. If you know you'll be stopped for a while, it's actually better to turn off your engine instead of idling.
Use Cruise Control
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
Use Overdrive Gears
When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.
