SN grade fully synthetic motor oil? Thank you

Mobil does decay faster, a few years ago, fortunately, in the past two years, the localization of the PAO content is about to drop is gone, and it is inevitable that the attenuation will be fast. No matter how good the SN grade fully synthetic engine oil is, you can look at the German GT engine oil, this PAO content is the highest on the market, there is 50%, and the additives of liquid molybdenum are only available in this brand, with strong anti-wear performance, more than 10,000 kilometers of attenuation, and can be replaced according to the maintenance cycle of 15,000 kilometers.

Different grades: SP grade oil is higher than SN grade oil, SN and SP are both grades of engine oil, SP grade oil has a longer service life than SN oil, and the lubrication performance is also better.

Whether it's SP oil or SN oil, they are all grades of API certification standards. Although the best oil for your vehicle is the best, the SN grade oil is the latest grade. Theoretically, SP oil is better than SN oil and has a better working capacity.

Precautions for the use of engine oil.

Engine oil is a necessary lubricant to ensure the normal operation of the engine, its specific role is to lubricate metal parts, reduce the friction between parts, take away the huge heat generated by the engine when doing work, clean the fine metal debris produced after wear, as well as sealing, shock absorption, rust prevention and other functions, so choosing a suitable oil for your car will directly affect the service life of the vehicle.

SP is the latest and highest-grade engine oil grade in the current API standard, and the biggest difference between SP and SN is that.

1. SP engine oil solves the problem of low-speed pre-ignition of turbine cylinder pressure direct injection engine 2. It improves the protection of engine timing chain wear.

It's just that the overall performance is a little better.

However, there is no direct connection between SP and China VI emission standards!

Models with particulate traps in China VI emission models require low ash content of engine oil, but SP does not have ash requirements.

That is to say, the oil of the SP may be high ash or low ash.

If your car comes with a particle trap.

When choosing engine oil, look for SP engine oil with low ash formula.

The differences between SN and SP grades of fully synthetic engine oil are: 1. Different phosphorus content: the phosphorus content of SN engine oil is relatively small; SP engine oil has a higher phosphorus content.

2. Different grades: SN is the second grade of engine oil; SP is the highest grade of motor oil. 3. Oil film:

The oil film of SN is relatively weak; The oil film of SP is relatively strong. 4. Protection performance: SN protection performance is average; SP protection performance is relatively strong.

SP's more advanced. Higher quality.

P-grade oil is higher than SN oil, SN and SP are both grades of oil, SP grade oil has a longer service life than SN oil, and the lubrication performance is also better, oil is something that every car owner needs to contact during the car, and the oil is called the blood of the engine.

The fully synthetic engine oil S series is a special oil for gasoline vehicles, and the C series is a special oil for diesel vehicles, and when it is marked with S and C, it is a general oil for gasoline and diesel vehicles. There are currently 13 kinds of S series engine oils, namely, etc., in alphabetical order, the lower the letters, the better the performance of the engine oil, that is to say, the oil of SP is better than the oil of SN in all aspects.

Fully synthetic oil SN is better than SP, and generally Mobil and Castrol SN oil is very good.

The difference between SN and SP is the thickness of the oil at a certain temperature, and it can also be said to be the difference in the degree of consistency (phosphorus content), and the phosphorus content of SN oil is relatively smaller;

Moreover, the viscosity of the two oils of SN and SP is larger than the viscosity value of SP, which means that the oil film of SP is stronger than SN, and has better protection effect, and SP has a stable improvement in quietness, fuel consumption and acceleration performance compared with SN.

The difference between SP grade and SN grade of fully synthetic engine oil is that the thickness (phosphorus content) of the engine oil at a certain temperature is different, among which the phosphorus content of SP grade is a little smaller than that of the same period last year, which can reduce the loss of the three-way catalytic converter, and basically has a stable improvement compared with SN grade in terms of silence, fuel consumption and acceleration performance.
