Nobody likes spending an arm and a leg at the pump. What can motorists do to improve gas mileage besides buying a new electric car? There are certainly driving habits that prevent unnecessary fuel loss. The biggest key to fuel efficiency, however, lies in the condition of certain parts under the hood. During your next auto maintenance, have the mechanic examine the following four car parts for improving gas mileage.
1. Mass Air Flow Sensor
This part measures the flow of air into the engine and transmits the data to the engine’s computer, which in turn regulates the transmission, ignition system, and fuel injection. A dirty mass air flow sensor causes inaccurate readings and inefficient operation.
2. Oxygen Sensor
As implied in its name, the oxygen sensor measures the level of O2 in the exhaust and sends the information to an onboard computer that regulates air and fuel mixture. A faulty oxygen sensor not only increases fuel consumption but also increases emissions, which can lead to failure of your next emissions test. As a general rule, the oxygen sensor should be replaced every 100,000 miles.
3. Air Filter
Gasoline needs a steady supply of air in order to create the spark that propels the car to move. When the air filter is blackened and badly clogged, it’s going to severely inhibit the airflow, thereby negatively impacting the gas mileage.
4. Spark Plug
According to the National Institute for Automotive Excellence, a spark plug that’s constantly misfiring can affect gas mileage by up to 30% and cost drivers an additional 94 cents per gallon at the pump.
Tune-Ups = Improved Mileage
A regular auto tune-up will reveal whether any of the parts listed need to be replaced. Replacing these car parts for better gas mileage not only saves you money at the gas station but also contributes to a smaller carbon footprint and a healthier environment.
