What does Castrol engine oil API SG JASO horse mean?

Api (american petroleum institute) is the abbreviation of api gravity, and the API grade stands for.

Oil quality grade. It uses a simple code to describe the working ability of oil.

API engine oils are divided into two categories: the series starting with "S" stands for gasoline engine oils, and the specifications are: API SA, SB,

SC, SD, SE, SF, SG, SH, SJ, SL. The series starting with "C" stands for diesel engine oil, and the specification is API.

Calcium, chromium, chromium, cadmium, cerium, californium, californium -2, californium -4, californium -4, californium -4. When the letters "S" and "C" appear simultaneously.

If it exists, it means that this oil is universal for gasoline and diesel.

The letter after s or c indicates; From "SA" to "SL", engine oil

Its performance will be better than the former, and there will be more additives in the engine oil to protect the engine. The later the letter, the more qualitative it is.

The higher the quantity grade, the more oil products with SF grade or above in international brands. For example, Shell Heineken Plus is API SL, while Shell Heineken engine oil is.

API SG level, which shows that the quality level of extraordinary Heineken is higher than that of HongHeineken.

S series stands for gasoline engine oil and C stands for diesel engine oil, but when S and C appear at the same time,

It means gasoline and diesel engine oil. The quality of engine oil varies from "SA" to "SL", followed by letters, quality, etc.

The higher the level. With each letter added, the performance of engine oil will be better than the previous one, and more engine oil will be used to protect hair.

Incentive additives.

1. The brands of oil used in Winter are: 0W, 5W, 10W, 15W, 20W, 25W, and the symbol w stands for winter.

The abbreviation of day), the smaller the number before w, the smaller the low-temperature viscosity, the better the low-temperature fluidity and the lower the applicable minimum temperature;

2. The brands of oil used in summer are: 20, 30, 40 and 50 respectively. The higher the numerical value, the greater the viscosity and the higher the applicable maximum temperature.

High;

3. The brands of general oil in winter and summer are: 5W/20, 5W/30, 5W/40, 5W/50, 10W/20, 10W/30.

10W/40、 10W/50、 15W/20、 15W/30、 15W/40、 15W/50、20W/20、20W/30、20W

/40, 20W/50, the smaller the number representing the winter part, the higher the number representing the summer part and the higher the viscosity, which is appropriate.

The wider the temperature range.

(1) High temperature type (such as SAE 20 ~ SAE 50): The number indicates the viscosity at 100℃, and the higher the number, the higher the viscosity.

(2) Low temperature type (such as SAE OW ~ SAE 25 W): W means only used in winter. The smaller the number, the lower the viscosity and the higher the low-temperature fluidity.

All right.

(3) All-weather type (such as SAE 15W/40, 10W/40, 5W/50): It means that the viscosity grades meet the requirements at low temperature respectively.

SAE 15W, 10W, 5W requirements, and the viscosity grade at high temperature meets the requirements of SAE40 and SAE 50 respectively, belonging to Dongxiatong.

Use type.
