Clean Air Filters:
A filter congested with dirt, dust, and bugs can waste gas and cause the engine to lose power burning too much gas trying to breath through the clogged filter. The intervals in which you replace your filter can depend on how much you drive and where you drive. For the best fuel economy have your technician check your filter during your regular maintenance.
The amount of spark plugs you have depends on your vehicle but normally there are four, six, or eight spark plugs. These plugs fire as many as 3 million times every 1,000 miles, resulting in heat, electrical, and chemical erosion. A dirty spark plug can cause misfiring, which wastes fuel. Check your car manual to find out when your spark plugs should be replaced.
Oxygen Sensors (O2 sensors):
When it comes to improving your vehicle fuel economy, this is one the top ways to make a noticeable difference. Properly functioning oxygen sensors are good for the environment and can save hundreds of dollars in fuel costs over their life. Replacement intervals for oxygen sensors are similar to those for spark plugs, ranging 30,000 – 100,000 miles depending on the sensor.
Properly Inflated Tires:
When tires aren’t inflated properly, it’s like driving with the parking brake on. Under-inflated tires can cut fuel economy by 2% per pound, which means if your tire pressure is 27 pounds per square inch (psi) when it should be 32 psi, you’ve reduced your gas mileage by 10%! Your technician should check them during your regular maintenance but having a simple tire gauge and checking regularly can tell you quickly if your are wasting gas due to under-inflated tires.
Oil and Filter Change:
Clean oil reduces friction between moving parts in your engine. Increasing fuel economy and reliability. It also removes harmful deposits, extending the life of your engine. Check your vehicle’s owner manual for the recommended oil and filter change schedule.
Locking Gas Caps:
Locking gas caps can contribute to fuel economy by preventing theft. Gas caps are available that include a dual breakaway feature and reinforcing ring that help deter thieves trying to steal fuel. If someone tries to pry off the cap the top of the cap will break away, leaving the cap neck in the tank. This will deter even the most determined thieves who are unlikely to take the time needed to pry the neck from the tank. Caps are also available that lock into the neck automatically, which saves motorists time.
