How about Castrol engine oil?

Castrol is a world-recognized lubricant expert with excellent quality.

Castrol has lubricant production plants in many countries around the world, especially in Britain, the United States, France, Germany, Italy, Japan, Australia and other countries with 12 technology research centers. Strong financial resources and first-class technology ensure that Castrol lubricants become more and more excellent products.

Castrol multi-pole protection: The notable feature of Castrol multi-pole protection is that it can reduce mutual friction between parts, improve power and reduce fuel consumption.

CastrolMAGNATEC magnetic protection: when the engine is cold, most of the engine oil is collected on the oil pan, and the surface of the parts lacks oil film protection and is easy to wear. The notable feature of Castrol magnetic protection is that it can reduce the wear of the engine during cold start, thus prolonging the life of the engine.

Castrol Castrol Jinjiahu: With the increase of age, sludge will inevitably accumulate in the engine, which will not only block the oil circuit, but also wear out parts. The remarkable feature of Castrol Jinjiahu is that it can remove the sludge from the engine, reduce the sludge and protect the stable operation of the engine.

Oil grade:

In fact, it is the viscosity of engine oil, which is divided into low temperature viscosity and high temperature viscosity. The low temperature viscosity affects the starting ability of the engine at low temperature, and the high temperature viscosity affects the protection ability of the parts when the engine is running. The oil label is divided by the letter W. The number before W represents the low temperature viscosity, and the number after W represents the high temperature viscosity.

The smaller the number before w, the better the low-temperature viscosity and the stronger the engine's low-temperature starting ability; The greater the number after w, the greater the viscosity at 100 degree, and the thicker the oil film formed on the parts. But the higher the viscosity at high temperature, the better, because the higher the viscosity, the greater the movement resistance of the parts, so we should choose according to the actual situation.
