For many people, Castrol engine oil is not particularly outstanding in performance. Among the six functional balances of engine oil, the comprehensive quality of Castrol engine oil is the most general. However, Shell engine oil is favored by people for its unique patented technology and superior cleaning performance.
The advantage of Shell lubricating oil lies in its cleaning power. After the car is used for a period of time, it will produce dirt, sludge and carbon deposit, which will help keep the engine clean and improve fuel efficiency. Its characteristics are high wear resistance, long service life and greatly improved system efficiency.
Take Shell's most popular extraordinary Heineken engine oil as an example. This product adopts Shell's unique technology patent PurePlus technology and power cleaning dispersion technology. The former can convert natural gas into crystal clear base oil with almost no common impurities, while the latter makes Shell engine oil have super clean efficiency, low volatility, better oxidation stability and better low-temperature characteristics, which can fully meet the protection of the engine, and is very helpful for prolonging engine life, reducing maintenance cost and fuel consumption, and improving fuel economy.

Matters needing attention in selecting engine oil
1, the choice of engine oil should be based on the requirements of the engine. An engine with lower requirements does not have to use too high-grade engine oil, and an engine with higher requirements cannot use lower-grade engine oil.
2. Multi-grade oil should be selected as much as possible. Multi-grade oil has the advantages of economy, long service life and high efficiency, and has a good protective effect on the engine. Based on the characteristics of multi-grade oil, it is normal that there may be premature blackening and oil pressure reduction during use.
3. The quality of some domestic famous brand engine oils is quite good, and the price is much lower than that of imported similar products, so you can use them with confidence. There is no need to blindly pursue "foreign oil".
4. If the engine is in good condition and the seasonal temperature is low, try to use low viscosity engine oil to make the oil circuit smooth. For example, in the high temperature season or in the case of serious engine wear, choosing high viscosity engine oil is conducive to the formation of oil film and reducing engine wear.
