Is There a Difference Between Engine Oil and Lubricating Oil?

[LeJayce]

The difference between engine oil and lubricating oil lies in their different uses: 1. Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks; 2. Lubricating oil is used on machinery to reduce friction between parts, providing lubrication and cooling during operation. The method for changing engine oil is: 1. Lift the car, remove the protective plate, and place a container under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain screw after draining, and wipe with a tissue to check for leaks; 3. Reinstall the protective plate, lower the car, and add oil through the filler port.
