Shell, Castrol, BP, Mobil, Esso and other well-known British and American engine oil products have long been household names, especially in the high-end market, occupying an absolute advantage. On this basis, the giants continue to supplement the mid-end products and extend the product front downwards. Great Wall, Kunlun and Uni-President are the representatives of domestic engine oil, and their quality is also guaranteed.

castrol

magnetic protection is a breakthrough technology of castrol in the field of engine oil. Castrol's main gasoline engine oil products are: Champion synthetic engine oil, Magnetic Protective Engine Oil, Jiaprotective Engine Oil and Protective Engine Oil.

Jiahu engine oil is an upgraded product of the original Castrol luxury engine oil. It is added with "active synthetic protective molecules", which can maintain lubrication function at low temperature and provide stronger rust protection and wear resistance.

Usually use high viscosity engine oil in hot weather. In southern China, such as Guangdong, 15W-4 viscosity grade engine oil is generally called all-weather engine oil.

In addition, high-end cars or new cars use oil with good fluidity and slightly lower viscosity because of the precise clearance of parts, but older cars can choose high-viscosity oil with relatively condensed sealing performance because of the large wear of parts.

generally, changing different brands once or twice will not be bad for the engine, but it is not recommended to change the brand of engine oil frequently, which will still have an impact on the engine (mainly the service life)

I hope it can help you and hope to adopt it.
