车主们对爱车的呵护保养之心不亚于照顾小孩，总是想着给爱车各种添加剂，希望爱车保养使用得更长久。诸如各种抗磨剂、清洗剂、修 复剂之类的商品不胜枚举。部分汽车维修企业为了追求利润大化，在车辆保养时向车主大力兜售各种添加剂。维修专家们表示，正规厂家的抗磨剂、修 复剂对部分已经磨损的车辆有一定修 复作用，乱加不合格添加剂可能引起润滑油性质的改变，造成润滑系统效率降低、油品变质等，反而加重机械磨损。对于新车来说，在不了解产品性能的情况下，是什么都不加。
Car owners care about their car as much as they care for their children. They always want to give their car various additives. They hope that their car maintenance will last longer. There are numerous commodities such as various anti-wear agents, cleaning agents and repair agents. In order to maximize profits, some automobile maintenance enterprises vigorously sell various additives to vehicle owners during vehicle maintenance. Maintenance experts said that the anti-wear agents and repair agents of regular manufacturers have a certain repair effect on some worn vehicles. Indiscriminate addition of unqualified additives may cause changes in the properties of lubricating oil, reduce the efficiency of lubricating system and oil deterioration, but aggravate mechanical wear. For new cars, nothing is added without understanding the product performance.
In addition, the effect of a large number of disassembly free cleaning agents for electronic throttle, fuel injection nozzle, air inlet and other components is limited. It is better to go to a regular repair shop for disassembly and cleaning on a regular basis.
Many car owners, whether major or minor maintenance, completely rely on 4S stores or repair shops. It is precisely by taking advantage of the characteristics that car owners rely on.

In fact, if we can master some conventional vehicle maintenance knowledge, such as vehicle oil inspection or replacement, we can reduce a lot of vehicle costs.
