What are the functions of fully synthetic engine oil?
2 Answers
Fully synthetic engine oil has the following functions: 1. Lubrication to reduce wear - There is rapid relative sliding between the piston and cylinder of the engine, as well as between the main shaft and bearing shells. The oil forms a sufficiently thick oil film between the two sliding surfaces to separate the relatively sliding parts and reduce wear; 2. Cooling - The oil can bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; 3. Cleaning - The oil can circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of the lubricating oil; 4. Shock absorption - When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, the load is transmitted through the bearings for lubrication, cushioning the impact load.
I always use full synthetic oil in my car because it provides superior lubrication for internal engine components, reducing friction and wear, making the engine run smoother and last longer. It doesn't thin out easily at high temperatures, protecting parts from damage, with excellent cooling effects to prevent overheating and engine seizure. Its cleaning power is also strong, removing dirt and impurities to avoid sludge buildup, keeping the engine clean and efficient. It enables quick cold starts without freezing the engine, ensuring smooth ignition even in winter. Much more durable than mineral oil, I only change it every 10,000 kilometers, saving both money and hassle. It also slightly reduces fuel consumption and improves engine efficiency, making the car feel more powerful. In short, for new or high-performance cars, this is a must-have option that can extend engine life by several years, avoiding the headache of major repairs.
