95% oil leakage is caused by corrosion and aging of oil seals. Over time, affected by the alternating temperature of cold and warm, rubber parts will lose plasticizer, and rubber parts will become hard and lose elasticity, resulting in poor sealing. Mattie ds contains high-efficiency plasticizer, which can penetrate into or be absorbed by the seal, so that the lost plasticizer of the seal can be replenished, and the seal can be re-expanded to restore its elasticity, thus solving the oil leakage problem.
The engine is not just an oil seal. Changing an oil seal may not solve the problem. Many car owners have changed the oil seal, but it has not been solved. Marty ds can act on all oil seals to solve the corrosion and aging problems of all oil seals.
