- Uneven Tire Wear: Skipping tire rotations can result in reduced traction, making your vehicle less stable and less safe on the road.
- Clogged Air Filters: A dirty air filter reduces airflow to the engine, decreasing fuel efficiency and making your car work harder.
- Dirty Transmission Fluid: Old, contaminated transmission fluid can lead to rough shifting, slipping gears, and even transmission failure.
To avoid these issues, maintaining clean filters and preventing problems like engine timing chain failures is crucial.
