Can I switch from 40 oil to 30 oil?
1 Answers
Whether you can switch from 40 oil to 30 oil depends on whether the engine is compatible with it. If the engine can use 30 oil, then there is no problem. However, if the engine does not allow the use of 30 viscosity oil, do not switch, as it may accelerate engine wear. Engine oil is the lifeblood of the engine, serving not only as a lubricant but also providing cleaning, sealing, buffering, rust prevention, and heat dissipation functions. Without engine oil, the engine cannot operate properly. During engine operation, the oil forms a protective film on the surfaces of various components, preventing direct contact and friction between them. If engine components come into direct contact and friction occurs, it will increase engine wear. Over time, the performance of engine oil degrades, so it needs to be replaced regularly.
