Always be particular about where you fill the fuel in your car. Make sure that it is a trusted quality filling station. The adulterated fuel can lead to a host of problems for the engine and cause huge expenses. Tropical and dusty conditions as in India can clog fuel lines and filters. Get the tanks properly checked once a year.

Certain vehicle components require periodic replacement. These are:

Fuel filter: A dirty fuel filter may result in engine stalling and loss of engine power.

Air filter: Dirty air filter results in loss of engine power, increased fuel consumption, airflow sensor failure, etc.

Spark plug: Spark plug replacement can significantly improve the engine performance.

Timing belt: Timing belt failure may cause serious engine damage, especially if it's diesel engine.
