Fuel Economy Tips

Fuel economy continues to be a hot topic and Car-X Auto Service provides many services to help you maintain favorable fuel efficiency, such as:

• Tires - Repair/Rotations
• Oil Changes
• Tune-Ups

Other ways in which to improve your fuel economy:

Properly Inflated Tires
The National Highway Traffic Safety Administration says that 25% of cars have one tire that is under inflated! That’s dangerous and wastes gas. Each year 33,000 injuries result from accidents caused by under inflated tires. Keeping your tires properly inflated can save you 12 cents per gallon in gas.

Don't Drive So Fast!
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: $0.12-$0.76/gallon

Observe the Speed Limit
As a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.20 per gallon for gas.

Observing the speed limit is also a safety precaution.
• Fuel Economy Benefit: 7-23%
• Equivalent Gasoline Savings: $0.16-$0.53/gallon

Remove Excess Weight
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%. 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: $0.02-$0.05/gallon

Avoid Excess Idling
Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

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 $2.31/gallon.

Data Sources:
• Estimates for fuel savings from sensible driving are based on studies and literature reviews performed by Energy and Environmental Analysis, Inc., Washington, DC.

• Estimates for the effect of speed on MPG are based on a study by West, B.H., R.N. McGill, J.W. Hodgson, S.S. Sluder, and D.E. Smith, Development and Verification of Light-Duty Modal Emissions and Fuel Consumption Values for Traffic Models, Oak Ridge National Laboratory, Oak Ridge, Tennessee, March 1999.
