Which grade of fully synthetic motor oil is better

Of course SN grade is the best, it is the highest grade among gasoline engine oils. However, note that the grade does not reflect the performance. Some ordinary mineral engine oils are also the highest grade SN, but it does not mean that they have the same performance as fully synthetic engine oils. It's just SM grade, or even just SL grade, but it's more powerful than many SN grade engine oils. Don't blindly pursue grade, that's just a cloud. Many small brands of engine oil in China are labeled as SN grade, but they are just written in vain and have not been certified by the world's authoritative organizations. Certification. If you want to use high-performance engine oil, it mainly depends on the brand and price. Their fully synthetic performance is definitely the same as Mobil 1, Castrol Ultra, Shell Helix Ultra, Great Wall Jinjixing J700u, Mote 8100. Powerful, red line, fast and powerful rainbow...these fully synthetic cars will definitely not let you down. Secondly, look at the price. Generally speaking, the price is as high as the expensive ones.

What grade of gasoline engine oil is it? Very good~

The gasoline engine starts with s and the diesel engine starts with c. The further back in the English alphabetical order, the higher the grade.

API engine oil is divided into two categories: the series starting with "S" represents gasoline engine oil, and the specifications are: API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM ,SN. The series starting with "C" represents diesel engine oil, and the specifications are: API CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. When the two letters "S" and "C" exist at the same time, it means that the engine oil is universal for gasoline and diesel engines. The meaning of the letters after S or C is; from "SA" to "SM", with each incremental letter, the performance of the engine oil will be better than the previous one, and there will be more additives in the engine oil to protect the engine. The further back the letters are, the higher the quality level. Among international brands, most engine oil grades are SF or above.

What is the best grade of Mobil oil?

Does anyone know what the highest grade of domestic and foreign engine oil is?

The highest level at home and abroad is SN level. However, the performance of SN grade engine oils from various manufacturers varies widely. Most of China's engine oils have not been certified by the World Petroleum Organization. Most of them are written by themselves, so they cannot be sold in Europe and the United States, and the quality is destined to not be very good. Another thing to know is that higher-grade engine oil does not necessarily perform better than lower-grade engine oil. Nowadays, high valve grade engine oils require environmental protection, which limits the amount of additives that are not environmentally friendly, such as phosphorus and molybdenum. However, phosphorus and molybdenum are indispensable and replaceable. Therefore, as far as the same brand is concerned, SN may not protect the car better than SL. Take a look at the world's top events! Racing engine oils only use SL, SJ, or even SG grades. Therefore, don’t blindly pursue high-grade engine oil.
