S is the oil class. N and p are the oil grade
Api (american petroleum association) divides oil oil into two categories: s: petrol oil, c: diesel oil。
There are 13 types of oil in the s series: sh, sj, sl, sm, sn and sp。
In alphabetical order, the next letter represents more oil than the first letter represents oil。
Sn is the second level of gasoline oil and sp is the highest level of gasoline oil at present
The most used are the sn, the sp, the sa-sh, which has been disabled and the others are less useful。
In the future, sqs and so on will not be fully represented at a higher level。
Differences in the effects of use:
Sp oils are effective in reducing wear and tear, reducing the generation of oil sludge and making it more clean and able to better protect engines, thereby increasing their useful life
2. Sp energy consumption, as the highest grade oil, has increased considerably and is more fuel-efficient than sn
3. Sp provides better quality prevention of early engine combustion, preventing early engine combustion at low speed and preventing engine damage。
Shells recommended for oil - gray shell, pioneer
Cleaning capacity must be at the forefront of industry. Shell oil is relatively clean, which removes oil sludge and carbon from vehicle parts and makes the engine smoother。
However, vehicles often travel at medium and low speed and for long periods of time, requiring frequent replacement of oil。
Greyshells are the classic for ever, with all-gas synthetic oils used in light-shadow shells, with good cleaning power and power
It is effective in preventing carbon sequestration, ensuring engine performance, extending engine life, 99. 5% purity, api sp grade:
If you want to choose the oil that meets the current g6 emission criteria, which is more effective and more silent, you can choose the constants, the pioneers, and the very pures of the extraordinaryness:
Mifu - silver and gold
The advantages of mobil oil are high technological content, good durability and high temperature resistance. The disadvantage is that when vehicles operate at high speed, the noise is high。
It's a closed-eye buying series. It's all technology, it's strong, it's long, it's mobile, it's fast
It helps to prevent the build-up of oil mud, helps to reduce the age of oil, and also protects engines for high temperatures, temperatures, colds and all kinds of bad driving environments:
If the budget is enough to recommend kimmy, kim has excellent hypothermia, excellent fuel economy, good cleanliness
There has also been an improvement in resistance, with all aspects of performance being superior to ginmeister:
Kazido -- magnetic, extremely protective
In the field of car protection, cartoon oil is definitely the first. When the oil is cold, when the engine starts cold
Performance is better, oil membranes are better formed, vehicles are well protected in cold weather, but cleaning performance is not strong。
This is a very protective series of oil that injects liquid titanium formulations with special oil membrane self-adaptation
Under various conditions, direct contact between metals can be effectively reduced, thereby reducing friction and ensuring excellent performance of engines:
The magnetic series focuses on the use of vehicles that are frequently activated and stopped in cities, and the unique intelligent molecules form self-rehabilitating oil membranes
Provision of up to 20 per cent of additional protection to protect vehicles at critical stages of parking start-up suitable for start-up:

In 2026, the oil selection campaign, the oil brand was recommended, and which oil was worth buying
The article details the selection of oil and believes that after reading it, you will know how to choose the right oil
