Causes of lubricant failure

Causes of lubricant failure

Engine overheating

Under the high-temperature conditions of prolonged engine operation, lubricating oil can undergo oxidative degradation, turning black and thickening. The high temperature of the engine leads to an increase in corrosive substances, carbon deposits, sludge, and varnish within the lubricating oil, thereby affecting the engine's lifespan.

Impurity effects

It mainly comes from dust in the air, metal wear particles, leaked substances (such as fuel, water, etc.), oxidized lubricating oil, and substances produced by fuel combustion.

Component failure

Some lubricants degrade in performance due to the depletion or failure of their additives; furthermore, base oil serves as the carrier for additives, and if the base oil fails, the additives will not function.
