How Long Can Full Synthetic Engine Oil Last?

[Blakely]

Full synthetic engine oil can last for 8,000 to 10,000 kilometers. The functions of full synthetic engine oil are: 1. Between the engine's pistons and cylinders, as well as between the main shaft and bearing shells, there is rapid relative sliding. The engine oil forms a sufficiently thick oil film between the two sliding surfaces, separating the surfaces of the relatively sliding parts to reduce wear; 2. It carries heat back to the oil tank and dissipates it into the air, helping the radiator to cool the engine; 3. It circulates carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil; 4. It provides shock absorption and cushioning when the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings. The load is transmitted through the bearings, and the lubrication cushions the impact load.
