Essential Maintenance Items for Volkswagen Lavida at 20,000 Kilometers
1 Answers
Generally speaking, the 20,000-kilometer maintenance is a major service for a car, typically being its third maintenance. Routine items include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Replacing the engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates substantially. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which could cause oxidation, leading to the formation of sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. The air filter serves to block dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer service. If the car uses standard material spark plugs, preparations should be made to replace them at the 20,000-kilometer mark. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel a lack of engine power while driving, maintenance should be performed. The service life of spark plugs varies depending on their material.
