Why Replacement is Important:

A worn oil pump cannot maintain the required flow and pressure, which leads to metal-to-metal contact, overheating, and accelerated engine wear. Timely replacement restores full lubrication efficiency and prevents severe damage.

Impact on Vehicle Performance:

Proper oil pump function ensures that engine components stay lubricated even under extreme duty. This results in more stable engine operation, reduced repair frequency, and dependable performance for commercial fleets.
