What is the reason for the oil seal leakage of BYD Sirui engine?

In fact, more than 90% of automobile oil leakage problems are caused by the aging of oil seals. And 95% of cars over 3-4 years old will have oil leakage problems. Engine oil leakage, gearbox oil leakage and steering gear oil leakage are all the same reasons.

Cause of oil leakage: Rubber seal is affected by alternating temperature change for a long time, and plasticizer will be lost. In this way, the seal will shrink, harden and lose its elasticity, and oil leakage is inevitable.

It is recommended to use Mattie DS, a high-efficiency additive imported from German original bottles, which contains high-efficiency plasticizer and can penetrate into or be absorbed by the seal. The seal will re-expand and recover its elasticity, and the wear of the shaft and sealing lip will be compensated. The sealing lip is closely connected with its own shaft and acts on all oil seals that come into contact with oil. Relieve in 5-7 days, 14 days.
