At present, with a turbocharged engine is very common, and turbocharger life has changed fundamentally, the correct use of maintenance, more than 200000 kilometres without failure is common. Most problems of turbocharger is because the turbocharger and the intake pipe between the oil seal damage, untight sealing oil leakage into the combustion chamber. But oil main damage more of the following reasons: one, using a turbocharged engine with mismatched oil, two, the oil change interval time is too long, three, incorrect use.
These are the result of the turbocharger causes of early damage. Turbo engine with common naturally aspirated engine rotation speed and temperature on the different lies in. The so-called speed mainly refers to the turbine shaft and bearing speed, full load can be up to the minute nearly 200000 rpm, in the high speed and temperature must request the main shaft bearing with full interior lubrication and cooling.
Therefore, the oil has certain requirements. One, to be good abrasion resistance, two, to three, high temperature resistant, high strength film, four, shear strength. To meet the above four points is the best choice of fully synthetic or semi-synthetic motor oil. Higher rotational speed requirements oil shear is more strong, the shear force is the guarantee of the stability of oil viscosity. The only way to make the high speed oil lubricating ability does not drop. Full synthetic oil is better than that of ordinary mineral oil, especially shear advantages especially.
