What is the difference between 2T oil and 4T oil?
1 Answers
4T oil and 2T oil differ in the following ways: 1. 2T oil: 2T oil refers to the oil used in two-stroke engines, also known as combustion oil. It is mixed with gasoline in a certain ratio and burns along with the gasoline. As a result, blue smoke can be seen coming out of the exhaust pipe. The higher the ratio, the more blue smoke is emitted. If no blue smoke is emitted, it indicates that the oil ratio is too low or there is insufficient oil. This type of oil has relatively low viscosity. 2. 4T oil: 4T oil serves the functions of lubrication, cooling, and cleaning. This oil does not participate in combustion. This is the biggest difference between four-stroke and two-stroke vehicles. Therefore, four-stroke engines normally have almost no carbon buildup and do not require carbon scraping for years. No blue smoke is visible from the muffler. If blue smoke is emitted when accelerating, it indicates that the vehicle is burning oil. The oil bottle's packaging will indicate the oil's grade and viscosity. For example, SJ10W-30 indicates that the oil is SJ grade, which is considered to be of relatively good quality.
