Using the right oil (up to 2%)
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 (up to 4%)
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% to 4%. 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 (up to 40%)
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 (up to 25%)
We’ve already mentioned changing your oil filter and keeping your tires properly inflated. 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%. If you haven’t been following your maintenance schedule, coming in for the Works Fuel Saver Package is a great way to start.
