How to choose the lubricating oil suitable for your car?

The viscosity of automobile lubricating oil should be selected according to the operating environment conditions of the initiator. The main consideration is:

1, temperature: often in high temperature conditions, should choose high viscosity; Often in low temperature conditions, should choose low viscosity.

2, load: the operation load is large, should use high viscosity. Smooth oil additives category of scientific and technological progress, smooth oil viscosity - temperature characteristics have been greatly improved, produced a compound viscosity of smooth oil such as SPC synthetic smooth oil 5W-50, it is still very good flow function at low temperature minus 30 deG C, viscosity will not drop too much at high temperature, to ensure that meet the oil film strength.

Secondly, we should also consider what grade of smooth oil to choose.

Now, in western shipping, the production and application of SE SF grade smooth oil has basically been suspended, while in China, due to a variety of reasons, some regions of the initial grade smooth oil is still popular. In fact, this is an important reason why our cars have short service life and high repair costs. So when we recommend the grade of smooth oil, it is a grade higher than the use of smooth oil in China now. The purpose of doing this is to expect that the broad driver friends can correctly use smooth oil, and then maintain your car, improve the service life of the car, and save the repair cost. Now, we select a representative car to illustrate the selection of smooth oil grade method: minivans generally can choose SE class; Shari can be SF level or above; Santana optional SG level and above; Honda optional SH level and above; Ford should choose the international cutting-edge SJ class.

However, cars with the following conditions should be upgraded by one or two grades:

(1) in the city, because of frequent traffic jam, stop and go, the operating temperature of the starter is unstable, simple carbon deposition, accelerated wear (70% of the wear of the starter occurs in the starting stage);

(2) Long-distance high-speed travel, the initiator is in high temperature state for a long time;

(3) fast moving, the speed of the starter is required to pull high, the frequency of the switch is fast, and the resistance of the machine changes dramatically;

(4) High load travel such as car loading, truck overload, then the engine needs to inhale more oil and gas to operate, driving speed is slow, heat dissipation is not good, general oil will lead to rapid deterioration and disintegration failure.
