Is fully synthetic engine oil suitable for general vehicles?

[DelJoy]

Fully synthetic engine oil is suitable for general vehicles. The functions of fully synthetic engine oil are: 1. Between the piston and cylinder of the engine, as well as between the main shaft and bearing bush, there is rapid relative sliding. The engine oil forms a sufficiently thick oil film between the two sliding surfaces to separate the relatively sliding parts and reduce wear; 2. It takes 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 on 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. It provides shock absorption and cushioning when the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston pin, connecting rod, and crankshaft bearings. The load is transmitted through the bearing lubrication to cushion the impact load.
