The engine is the heart of your car, and proper maintenance is crucial to ensure its long - term performance and reliability. Here are some key steps for engine maintenance:
4. Spark Plug Inspection and Replacement
Spark plugs ignite the air - fuel mixture in the engine cylinders. Worn or dirty spark plugs can cause misfires, reduced power, and poor fuel economy.
How to do it: Inspect the spark plugs at the intervals recommended in the owner's manual. If the electrodes are worn, the insulator is cracked, or there is a build - up of carbon deposits, replace the spark plugs. The replacement interval can vary from 30,000 to 100,000 miles depending on the type of spark plugs used.
