What is the best engine oil for Outlander?

[LeBryce]

Mitsubishi Outlander uses 5W30 engine oil. The following is the relevant introduction of engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and the cylinder, as well as between the main shaft and the bearing. To prevent excessive wear of parts, an oil film of sufficient thickness needs to be established between the two sliding surfaces to separate the relatively sliding parts, thereby reducing wear and extending mechanical life. 2. Cooling: Engine oil helps the radiator cool the engine and expels heat from the engine. 3. Sealing and leakage prevention: Engine oil can form a sealing ring between the piston ring and the piston, reducing gas leakage and the entry of pollutants. 4. Shock absorption: When the pressure at the engine cylinder port rises sharply, the load on the piston, piston pin, connecting rod, and crankshaft bearings suddenly increases. This load is transmitted and lubricated through the bearings, cushioning the impact load.
