Many owners don't know how to use oil. They also don't understand some of the oil's parameters. Here's a closer look at the choice of oil.
In fact, a lot of information on an oil is hidden in physical and chemical indicators. Therefore, to find the right oil must look at those physical and chemical indicators. In addition, since we want to combine theory with actual combat, here we will discuss the little ZOOMM engine oil that I currently use.
Let's talk about the temperature level, the number before w. 0w is minus 40 available, 5w is minus 35 and so on. This is very important for the north riders! Can not just look at the numbers, to see the pour point, that is, the condensation point, such as the same 5w40 Forsch gt1 pour -36, gray shell is -50 or so. According to my experience pour at least 10 degrees lower than the minimum temperature of the environment to be safe. Therefore, for the same 5W, for the north, especially the northeast, one can use a problem that cannot be used, is not easy to use, but can not be used, so at the beginning it was said that the choice of engine oil must be based on physical and chemical indicators.
Shear value. Shear value response oil film strength, the same viscosity The higher the shear value, the higher the oil film strength, the better the engine. I now use the ZOMO Prime Engine Oil to add the top-grade additive: M-PolanetTM, a multi-polar network oil film technology, which operates continuously under high temperature and high pressure conditions and can form on the friction surface without affecting the original characteristics of the oil. The high strength oil film can reduce wear more effectively, exhibit extraordinary oxidation stability, and maintain high shear stability of the oil. The abrasion resistance is very strong, which also makes my life of the engine much longer. Therefore, bikers must pay attention to the shear value when selecting gasoline.
Oil cleaning performance is also a concern for many riders. To know how the oil's cleaning performance is concerned, it is necessary to look at the total base value tbn, which directly affects the oil life cycle and cleaning performance. Because the clean dispersants are all medium and high base substances, a considerable portion of the tbn comes from the clean dispersants of the oil. The higher the tbn is, the stronger the dispersant is, and the stronger the ability of the oil to neutralize the acidic oxides and disperse warm slushes. The total base number of ZOOMM engine oil currently used is slightly higher than it, and the apparent cleaning ability is much better than that of previously used engine oil.
