how to get fuel economy in vehicle.Some of the procedure are include:
1.Ensure tires are properly inflated. The owners manual for the vehicle will indicate the proper pressure to inflate you tires to. Decreased tire pressure increases the rolling resistance of your tires and decreases fuel economy, and may also increase tire wear and impair performance.
2.The thermostat, oxygen or O2 sensor should be replaced either at a manufacturer recommended interval or when a electronic fault code/ low temperature problem is detected. Electronically fuel injected vehicles have an O2 sensor or sensors in their exhaust system which helps the vehicles computer determine how to optimize fuel economy. These O2 sensors may need to be changed periodically for a vehicle to optimize it's air fuel mixture and maximize it's fuel economy.
3.Insure vehicle air filters are clean. Black or otherwise dirty air filters make your engine work harder to get enough air for proper combustion and decrease its efficiency; however, electronically fuel injected cars can automatically compensate for the decreased air flow caused by a dirty air filter and experience relatively little decrease in fuel economy. Most owners’ manuals will recommend a service interval at which to change the air filter, but periodic visual inspection is the best way to ensure that the air filter is clean.
4.Using the recommended weight of oil can decrease the burden on the engine. Heavier oil weights, such as 20W-50, are harder to maneuver through the engine than, for example, 10W-30 or 5W-20 oils. The result can cause a decrease in fuel economy.
In some countries, the completed services are recorded in a service book which is rubber-stamped by the service center upon completion of each service. A complete service history usually adds to the resale value of a vehicle.
