The most vulnerable to a problem: too much oil. The dangers of engine oil missing many owners know, bearing and shaft friction will be less because of the amount of oil, poor lubrication and aggravate the wear degree, even cause burn wazhou accident. In order to reduce the number of add oil, convenient maintenance and add oil when maintenance of many cyclists, too. Too much oil, the engine crankshaft, connecting rod big end handle at work will produce violent agitation, not only increase the engine internal power losses, and can make the increase in the number of the oil splashed onto the cylinder wall, burn oil line fault. Therefore, oil should be controlled in the oil in the engine oil pan feet between upper and lower scribed line.

After the transport costs, many motorists began to driving less, some only drive in holidays, in this way, the engine and gearbox transmission parts surface rust due to often is in a state of direct contact with air. Every few days is the best way to let the car run on thirty or forty minutes.

The belt is not tight, the better. Such as fan belt, improve the tightness of fan belt, can improve the effect of engine cooling, thus 1 vigorously improve the tightness of fan belt, fan belt too tight, but this kind of practice is wrong. Fan belt should keep elastic appropriate, because is too big, too tight will make bearing load increasing, increases power consumption, wear at the same time also can make water pump shaft bending, belt stretching deformation, shorten service life.

Make these problems are not just new owners, many older drivers like according to their own experience to judge all kinds of maintenance, but often have big discrepancy between manual with cars. Each owner to buy a car will have a maintenance of the periodic table, have been told when this how to do maintenance, but most of the owners open open, as long as you feel good, have no what problem, also gradually put behind.
