How to Reinsert the Dipstick?

[AubreyAnn]

Push it all the way in. Here are some key functions of engine oil: 1. Reduce wear: There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearings. To prevent excessive wear, a sufficiently thick oil film must be established between these sliding surfaces to separate them, thereby reducing wear and extending mechanical life. 2. Cooling: Engine oil helps the radiator cool the engine by dissipating heat away from the engine. 3. Sealing and leak prevention: Engine oil forms a seal between piston rings and pistons, reducing gas leakage and preventing contaminants from entering. 4. Shock absorption: When pressure in the engine cylinder rises sharply, the load on pistons, piston rings, connecting rods, and crankshaft bearings increases suddenly. This load is transmitted and lubricated through the bearings, cushioning the impact load.
