The turbocharged engine oil choice

With a turbocharged engine is very common, and a fundamental change in the life of the turbocharger, correct maintenance, more than 200,000 kilometers without failure is also common.And most of the problems of a turbocharger because of seal damage between the turbocharger and the intake pipe, closed lax oil leakage into the combustion chamber. The main reason for the oil seal damage confined to the following points: First, the use does not match with the turbocharged engine oil, two oil change interval is too long, incorrect use.

These are lead to reasons turbocharger early damage. The turbocharged engine with a naturally aspirated engine lies in the speed and temperature. The so-called speed refers to the speed of the turbine shaft and bearing the full load capacity of up to of nearly 200,000 revolutions per minute, this high speed and temperature must be sufficient lubrication and cooling requirements of the bearing of the main shaft indoor.

Therefore, certain requirements for oil. A good abrasion resistance to high temperature, high film strength, shear and strong. Meet more than four points the best choice is a full synthetic oil or semi-synthetic oil. The higher the speed, the oil resistance to shear force, shear force is the protection of the oil viscosity stability. Only in this way can the lubricating ability of the oil at high speed does not drop. Fully synthetic motor oil is better than ordinary mineral oil, in particular, the advantages of the shear force is particularly prominent.

The best option is to fully synthetic oil or semi-synthetic motor oil, the higher the speed the stronger oil shear force
