9 Ways to Be Fuel Efficient and Help Save Gas

It is always good to look for ways to help improve fuel efficiency and save money at the pump. Below are nine tips, from the U.S. Department of Energy to help you conserve gas. These are some things you and your GM Certified Service experts can do to help improve your fuel economy.

1. Tune-Up
Properly tuning your engine can improve fuel economy by as much as 4 percent. Similarly, fixing a serious issue, such as a faulty oxygen sensor, can boost mileage by as much as 40%. Consult your Owner's Manual or GM Certified Service Technician for the appropriate time/mileage to perform a tune-up.

2. Check Tires
Properly inflated tires improve gas mileage by as much as 3.3 percent. Refer to your vehicle's Owner's Manual to determine the proper tire pressure for your car.

3. Unpack
An extra 100 pounds of cargo reduces fuel efficiency by as much as 2 percent. A loaded roof rack cuts fuel efficiency by up to 25 percent on the highway. When possible, try to cut back on unnecessary cargo in your car.

4. Slow Down
Always try to drive at a moderate speed. Gas mileage will begin to decrease rapidly at speeds above 60 mph. An easy way to remember this is to add $0.25/gallon of gas for every 5 mph over 50 mph you drive. With this example, you are paying $0.50/gallon more if your drive 60 mph.

5. Quit Idling
It is important to avoid idling. Remember that a car gets 0 mpg when the engine is idling. Idling can use a quarter to a half-gallon of fuel per hour, depending on engine size, air conditioner use and use of other accessories.

6. Chill Out 
Speeding, rapid acceleration and rapid braking can decrease fuel economy by 33 percent on the highway and 5 percent in city driving. Cut down on erratic driving to use your vehicle as efficiently as possible.

7. Put It In Overdrive 
Using an overdrive gear on the highway saves fuel and avoids excessive engine wear. Essentially, overdrive works as your vehicle's highest gear; the more that you use overdrive, the better your gas mileage will be.

8. Use The Right Oil 
Using the manufacturer's recommended grade of oil can improve fuel efficiency. Refer to your Owner's Manual for more information.

9. Plan Your Trips
Plan routes and timing to avoid heavy periods of traffic congestion. The constant stop-start of a traffic jam will only waste fuel.

Your local GM Certified Service technician can inspect your vehicle and perform services to help it operate at peak performance and increase overall fuel economy. These inspections and services may include items such as:

  • Changing engine oil and using the recommended grade of motor oil
  • Checking and changing your air filter regularly
  • Inspecting and replacing a clogged fuel filter
  • Adjusting tire pressure to manufacturer-recommended specs
  • Inspecting and/or cleaning the air intake system
  • Inspecting and replacing failed emissions components or a faulty oxygen sensor
  • Cleaning or replacing dirty or malfunctioning fuel injectors
  • Inspecting and replacing spark plugs and spark plug wires
  • Checking exhaust for clogged catalytic converter
  • Examining the exhaust gas recirculation system
  • Performing a diagnostic check for stored trouble codes on your vehicle’s computer that indicate malfunctioning systems
  • Treating your vehicle with Fuel System Treatment Plus. It cleans carbon deposits from carburetors, fuel injectors, intake valves, intake ports and combustion chambers.
