Along with the flow of years, the progress of the times, the car has quietly into ordinary people's home. The car is no longer just a means of transport, it is more like our friends, and even into our family, as a family member. We took care of their car, even to the extent of "love", of course, can not ignore the details of his own car. Instant you really "love" it, also can not love too much. For example, you are in order to better protect the engine, the oil is added to the full, these are not the right.

Error 1: oil better not less

The oil in the crankcase can not be much added, also can not be added, the oil will increase the number of crank connecting rod mechanism of the rotation resistance, but also to splash into the oil on the cylinder wall. Too much oil will cause the combustion chamber to accumulate carbon, engine power is reduced, which will affect the discharge. When the owner in check or add oil, should be in accordance with the oil scale above the scale, the highest level of oil level can not exceed the scale of the upper limit, the minimum can not be lower than the scale of the line, the oil level is usually added to the middle of the two scale position more appropriate.

Error 2: fetal pressure rather high can not be low

Some owners like to charge the tire pressure is very high, that not only can overload and saving, this approach is not correct. The tire pressure is too high will make the tire ground to reduce, tire surface wear and tear, reduce the braking effect, this will affect the driving safety. The tire pressure is too low, too low, the pressure is too low, but will affect the driving safety and braking effect, but also to speed up tire wear, and increase the vehicle's fuel consumption. Owners in the air pump is utilized to automatically inflate when, should according to the pressure specified by the manufacturer of inflatable, tire pressure label usually located in the body or the fuel tank cap above.

Error 3: the wheel screw tight not loose

Bolts of various parts of the car, according to different diameter, pitch and uses, the fastening force moment has the corresponding provisions, amounting to less than specified torque bolts are loose, more than the fastening bolt torque will be elongated. Before all parts of the fastening, the need to grasp the fastening torque of the bolts, such as the wheel bolts, the general situation of household car tire bolt tightening torque between M and 100-130N.

Error 4: Annex belt tightening loose

Some owners think that to improve the tightness of the annex belt, can improve the refrigeration effect of the compressor, and the generator's power generation, so it is a strength to improve the belt tightening, but this practice is wrong. Accessory belt shall keep proper tension degree, because the belt is too tight will make the bearing load is too large, will shorten the service life of the parts, but also lead to the break up of the belt, will eventually affect the vehicle normal use.
