Maintenance Tips to Help Your Subaru Save Fuel


Along with performing routine oil and oil filter changes, using the lightest grade of oil for your climate, season, and vehicle model will help improve fuel economy. Switching from higher viscosity oil reduces engine friction, and can result in a 6% gain in fuel economy.

A clogged air filter will make your engine work harder and use more fuel. Replacing a dirty air filter can improve mpg by as much as 10%.

A misfiring spark plug can cut fuel efficiency by as much as 30%. Replacing spark plugs according to owner's manual recommendations - an using Genuine Subaru spark plugs will help maintain maximum mpg.

Along with poor handling and uneven tire wear, wheel misalignment can cause a 10% drop in fuel economy.

Carbon deposits on air intake valves and in the throttle body reduce fuel economy. Genuine Subaru Engine Cleaner and Genuine Subaru Throttle Plate and Induction Cleaner can remove harmful deposits. Genuine Subaru Fuel Injector Cleaner Fluid can help prevent them.

A triggered Check Engine light could be signaling any number of problems that impact fuel economy. Diagnosing and repairing a faulty oxygen sensor, for example, can improve mpg by as much as 40%.

Tires under-inflated by just four pounds of pressure can cut mpg by 10%. Keep your tires
 properly inflated by checking their pressure often, and always when they are cold.

Driving Tips to Help Your Subaru Save Fuel
Bringing your vehicle into Stanley Subaru for Subaru service is an easy way to improve fuel economy. But so are these mpg-conscious driving and refueling tips, which you can practice out on the road, for real day-to-day savings:

Rapid acceleration and braking wastes gas. Avoiding jackrabbit starts and stops can increase fuel economy by 5%.

Fuel economy drops 2% for every mile per hour that you drive over 55. Just slowing down from 75 to 65 mph can increase mpg up to 15%.

Avoid traveling with unnecessary items, especially heavy ones - for every extra 100 pounds that a vehicle carries, fuel economy drops by 2%.

Idling longer than 60 seconds consumes more gas than stopping and restarting. If your stop is going to take more than a minute, turn the engine off.

Several short trips can use twice as much fuel as one long trip of the same distance. Save gas and time by combining your errands.

Gas has greater density at lower temperatures. Fill up during the cooler early-morning or late-evening hours, and you'll get more gas for your money.

Higher octane gas won't boost mpg, so unless your vehicle requires it, it's a waste of money. Using lower octane gas in a vehicle that does require it can result in power loss and engine damage.

Topping off a tank only results in gas sloshing around or seeping out. Don't waste the extra fuel dollars - stop pumping at the first click of an automatic fuel nozzle.

A loose, damaged or missing gas cap can allow gas to evaporate and cause a loss of up to 2 mpg.

At highway speeds, open windows cause air drag that burns extra fuel. Rolling them up can increase fuel economy by 10%.

Gas Mileage Tips from US Department of Energy:

Drive Sensibly
frustrated driver

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 gas money.

Fuel Economy Benefit: 5-33%
Equivalent Gasoline Savings: $0.17-$1.15/gallon

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 60 mph.

You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.28 per gallon for gas.

Observing the speed limit is also safer.

Fuel Economy Benefit: 7-23%
Equivalent Gasoline Savings: $0.24-$0.80/gallon

Remove Excess Weight

Excess items in trunk

Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2 percent. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.

Fuel Economy Benefit: 1-2%/100 lbs
Equivalent Gasoline Savings: $0.03-$0.07/gallon

Avoid Excessive Idling

'Stop Idling' Sign

Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner (AC) use. Turn off your engine when your vehicle is parked. It only takes a few seconds worth of fuel to restart your vehicle. Turning your engine on and off excessively, however, may increase starter wear.

Fuel Cost Savings: $0.01-$0.03/min. (AC off)

$0.02-$0.03/min. (AC on)

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.

Note: Cost savings are based on an assumed fuel price of $3.48/gallon.
