What Causes Oil Leakage in Civic's Transmission?

Civic transmission oil leakage is over 90% caused by aging seals (oil seals)! Seals (oil seals) harden over time, meaning they lose plasticizers as years go by. Causes of Oil Leakage: This process is exacerbated by the continuous alternation of working temperatures between hot and cold. The unfortunate result is that the seals first begin to shrink, then harden, and eventually even crack, making oil leakage inevitable. Solution: Add German-made MARTI DS to the oil. Under normal driving conditions, the oil leakage problem usually disappears naturally in about 14 days, without delaying vehicle usage. It also eliminates the need for disassembly and repair, avoiding the waste of time and money associated with such procedures. Moreover, it allows car owners to easily solve the oil leakage problem themselves with minimal effort.
