How Many Kilometers Should a Verna's Spark Plugs Be Replaced?
3 Answers
Under normal maintenance conditions, Verna's spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following standards for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage ignition wires according to the firing order, and then secure the cover.
After driving my Verna for several years, I've found that spark plugs should be replaced every 30,000 to 40,000 kilometers. It depends on your driving habits - if you frequently encounter city traffic jams, it's better to replace them around 30,000 km, otherwise the engine may vibrate noticeably or fuel consumption could increase. I once delayed replacement until 35,000 km, and the car shook violently during startup while fuel costs increased by over ten yuan. After promptly installing new spark plugs, the car immediately ran much smoother. During routine maintenance, remember to check the spark plug condition to prevent potential issues. When replacing, ordinary copper-core plugs are cost-effective and suitable for this car. Don't wait too long - engine health is most important.
From the perspective of spark plug types, the Verna commonly uses two types: standard copper-core or iridium. The standard ones have a shorter lifespan, requiring replacement approximately every 30,000 kilometers. They are cost-effective but require more frequent changes. I switched to iridium ones, which are more durable and last about 50,000 to 60,000 kilometers before needing replacement. Although they are more expensive, they are more convenient. Driving style also affects their lifespan; frequent hard acceleration can shorten it. Replacing spark plugs can improve engine efficiency and fuel consumption. My actual test data shows that timely replacement can save up to 10% on fuel. It is recommended to follow the manual's suggestion of starting at 30,000 kilometers and adjust based on actual conditions. Regular maintenance checks on the spark plug condition ensure safety and extend the vehicle's lifespan.
