Routine maintenance of the car is just maintenance for the lubrication system. Change the oil, filter, and air filter. My Touran has been used for more than 6 years and has driven more than 60,000 kilometers. In the early stage, I also successively replaced the air-conditioning filter element, the blower was cleaned, the spark plug, and the throttle valve were cleaned, but the problem of changing the oil and affecting the venue and tools was only carried out at the 4S shop. The oil and filter that were hoarded at the 4S store a year ago have now reached the maintenance deadline, and they are just in use.
