- Air filter: A clogged or dirty air filter can affect air-fuel mixture and reduce fuel efficiency.
- Spark plugs: Worn spark plugs can create ignition issues and decrease engine performance.
- Oxygen sensors: Faulty oxygen sensors can lead to incorrect air-fuel mixture ratios.
- Fuel injectors: Clogged or faulty fuel injectors can result in irregular fuel distribution.
- Transmission fluid: Old or insufficient transmission fluid can cause poor shifting and reduce gas mileage.
2. Aggressive Driving Habits:
- Fast acceleration and sudden braking increase fuel consumption significantly.
- Maintaining higher speeds on the highway reduces gas mileage.
3. Idling for Extended Periods:
- Leaving the engine running while stationary consumes unnecessary fuel.
4. Tire Pressure:
- Underinflated tires increase rolling resistance and decrease fuel efficiency. Ensure tires are properly inflated.
5. Excess Weight:
- Carrying unnecessary items in the vehicle adds weight and affects fuel economy.
6. Faulty Sensors:
- Mass Airflow (MAF) sensor issues can disrupt fuel and air calculations and lead to inconsistent gas mileage.
