Common Misunderstandings in Car Maintenance – Many Car Owners Are Making Them

Many car owners attach importance to car maintenance, but due to the lack of professional knowledge, they often fall into maintenance misunderstandings, which instead damage the vehicle. Misunderstanding 1: Frequent car washing. Excessive car washing will wear the car body paint, especially high-pressure water gun washing at close range, which is easy to scratch the paint. It is recommended to wash the car once a week. After rainy or snowy days, it can be cleaned in time to remove body stains and salt. Misunderstanding 2: Adding too much engine oil. Too high engine oil level will increase the engine running resistance, lead to increased fuel consumption and engine overheating, and may also damage the three-way catalyst. It should be controlled between the upper and lower scales of the oil dipstick. Misunderstanding 3: Blindly upgrading accessories. Randomly replacing accessories higher than the original factory specifications of the vehicle (such as spark plugs and brake pads) may not match the vehicle, affect vehicle performance, and even cause faults. Accessories replacement should follow the original factory standards. Misunderstanding 4: Long-term non-replacement of brake fluid and antifreeze, thinking that it is not necessary to replace as long as the level is sufficient. Little do they know that the oil will deteriorate over time, lose its original function, and bury potential safety hazards. Misunderstanding 5: Not maintaining the vehicle when it is parked for a long time. Long-term parking will cause engine oil deterioration, battery power loss, tire deformation, brake system rust, and other problems. The vehicle needs to be started regularly and protective measures should be taken.
