What Are the Consequences of Mixing Different Motor Oils?

[RileyFitz]

Mixing different motor oils can lead to the following consequences: 1. Altering the overall viscosity of the oil inside the engine; 2. Affecting the engine's service life; 3. Creating potential safety hazards such as oil burning and cylinder scoring. Motor oil is used for lubricating internal combustion engines, with its primary functions being to reduce friction and wear on moving parts, clean out sludge and varnish from the engine, neutralize acids produced by fuel and lubricant oxidation, improve piston ring sealing, and cool the engine by carrying away heat from moving components. The method for checking motor oil is as follows: 1. Open the car's engine hood; 2. Pull out the oil dipstick; 3. Insert it into the engine oil.
