Still hesitating to use what oil?

The classification of motorcycle engine oil quality is divided into two standards, one is to look at the API standard (the "American Petroleum Institute" standard), and the SAE standard (the "American Society of Automotive Engineering" standard). Yes, it’s all American standards... First, the API standard is a comprehensive measure of the quality of oil. The quality of oil is divided from low to high: SA, SB, SC, SD, SE, SF, SG. , SH, SJ, SL grades. SL is currently the world's highest quality motor oil.

These standards are in order from low to high:

• SA In the early 1930s, pure mineral oil, no additives.

• SB 194O, the first oil containing additives, containing some rust inhibitors and antioxidants.

• SC 1964 provides protection against high temperature and low temperature deposition, wear, rust and corrosion.

• SD 1968 performs better than SC oil.

• SE 1972 More protection against oxidation, rust, corrosion and high temperature deposition.

• SF 1980 oxidation stability is better than SE.

• SG 1989 controls engine deposition, oil oxidation and engine wear better than SF.

• The SH 1993 test pass program is stricter than SG.

• SJ 1996 world top motor oil.

• Upgrade version of SL 2002 SJ level.

Because grades represent different qualities, it is theoretically possible to use high quality oil. Because the better the quality, the better the life of the motorcycle is.

Let's talk about the SAE standard, which is a standard for measuring the viscosity of oil, and is divided into single viscosity and double viscosity. For example: SAE40 (single viscosity), SAE15W-50 (complex viscosity). In the double viscosity, W means winter. The smaller the number before W, the lower the oil resistance is. The larger the number behind W, the better the high temperature oil film retention.

At present, the oil produced by regular lubricant manufacturers is basically classified according to these two standards. Therefore, the API grade and SAE rating of the oil are indicated on the package of the product. What grade of oil is selected, the description of the vehicle or the casing of the engine will be indicated. For example, if the engine casing is marked with "SF", oil of SF or higher (including SF) can be used. Of course, the higher the oil level, the more expensive the price.

Now, there are some lubricant manufacturers who need to sell for the market (because many users don't know what kind of oil they want to use in their cars), and package the oil into "XX special oil". In fact, the quality of these oils. At best, it meets the minimum requirements of these locomotives (some even the minimum requirements are not met). This is like the minimum configuration of the game in the video game, the minimum configuration of the oil can only guarantee that your car can be used, and can not guarantee the most suitable for your car. If you know the two criteria for the classification of the oil, and if the economic conditions allow it, you can use a higher level of oil, which is more beneficial to the maintenance of the engine. And don't have to be superstitious about the so-called "special engine oil."

The last thing to note is that the engine oil is best to use genuine engine oil produced by regular manufacturers. Individual unscrupulous manufacturers are seeking profiteering, the level of virtual standard oil, and even secondary production with recycled waste oil. After the motor vehicle uses this inferior engine oil, the wear and tear of the engine will be intensified. Still, if you pay for the penny, the good thing in the sky, don’t believe it. If you really like your car, spend a little more money to buy a reassurance, why not?
