Easy Tips For Better Gas Mileage

The U.S. Department of Energy offers the following fuel saving tips:

  • Stay within posted speed limits. Each 5 mph you drive over 60 mph is like paying an extra 20 cents per gallon for gas.
  • Remove unnecessary items from your trunk. An extra 100 pounds can reduce fuel economy by 2%.
  • Avoid putting items on top of your vehicle. The wind resistance of a loaded roof rack can reduce fuel economy by 5%.
  • Under-inflated tires wear down more quickly and they also lower your car’s gas mileage.
Maintain Your Vehicle
  • A properly tuned engine can increase gas mileage by 4%.
  • Properly inflated and aligned tires can increase gas mileage 3%
  • Replace air filters regularly. Clogged filters can reduce gas mileage 10%.

Servicing Your Car

The following tips will help keep your car running efficiently, while reducing harmful emissions:

  • Change your oil and oil filter
  • Keep tire pressure and alignment correct
  • Make sure your car is properly tuned up
  • Check emissions control devices
  • When check engine light or other warning lights appear, service engine immediately
  • Use the correct type of oil and fuel for your car
  • Change your fuel filter
  • Check wiring, hoses and belts regularly
  • Check crankcase breather elements. We can show you how next time you come in.
  • Change your air filter

Car Care Checks

Every three months (or more often if specified by your vehicle owner’s manual) and before leaving on a trip or long distance drive, check the following or have us do a Campbell Auto and Tire Car Care Check.

  • Tire Pressure
  • Transmission fluid
  • Brake fluid
  • Power steering fluid
  • Radiator coolant
  • Windshield washer fluid

Why is it important to keep the fluids at their full-level marks? The fluids lubricate moving parts to reduce fiction, heat, and wear. Therefore, they are the single most important factor for extending the life of a vehicle.

Check the Anti-freeze:

Prior to winter, have Campbell Auto and Tire check the antifreeze with a hydrometer (a device that takes a sample of antifreeze and specifies how cold the temperature can become before the antifreeze freezes). The antifreeze should be able to withstand (i.e., not freeze) temperatures of at least 30 degrees “below the coldest” winter temperature. If the antifreeze is too weak, have additional antifreeze added to the coolant bottle.

Purchase the type of antifreeze as specified in the vehicle owner’s manual (i.e., usually a type that is suitable for “aluminum and all types of metals” that are used in today’s engines) to avoid frozen antifreeze because it can crack an engine’s block, which could result in possibly thousands of dollars in repair.

More Tips On How To Improve Your Gas Mileage

Gas prices are at record highs. People are asking, “What can I do to get better gas mileage when I drive?”. These are some of the things you can do to ensure improved gas mileage for your car:

Driving Habits:

  • Keep your car clean. Mud, slush or ice on the undercarriage of your vehicle can weigh
    a significant amount and slow you down.
  • Clear out the trunk. More weight, more drag.
  • Consolidate your daily trips and errands. This will also save you the cost of restarting your engine, which uses a lot of gas.
  • Avoid air conditioning when possible. However, when driving at higher speeds, having your windows open also creates drag.
  • Don’t throttle the gas or brake. Sudden starts or stops use more gas than gradual changes of speed.
  • Don’t idle for too long. Turn off the engine if you anticipate a lengthy wait. Limit car warm-ups in winter.
  • Avoid high speeds. We know this is almost impossible to resist but you can improve your gas mileage about 15 percent by driving at 55 mph rather than 65 mph.
  • Use overdrive. If your car is equipped with overdrive gearing use it as soon as your speed is high enough.
  • Use cruise control. Keeping a constant speed is ideal for improving your gas mileage.

Servicing Your Vehicle:

  • Improve the spark to your engine. This way, the air and fuel mixture will be burnt better.
  • Improve your intake/output system. Helping gas get in and exhaust out of your vehicle will improve overall performance and gas mileage.
  • Reduce friction. Use high-quality or synthetic motor oil.
  • Check your oil! Low oil makes your engine work harder.
  • Change your filters. Dirty filters can sometimes increase the amount of fuel your vehicle is using by 10 percent.
  • Keep tires properly inflated and aligned. Check regularly to ensure your wheels are fully inflated and your alignment is good.
  • Get regular engine tune-ups and car maintenance checks. A lot can go wrong with a car. Damaged spark plugs or transmission problems can also contribute to poor gas mileage.
