UNDERCHARGERS · PREVENTIVE MAINTENANCE
Preventive maintenance service and vehicle inspection from Underchargers, with branches in Quezon City, Mandaluyong and Las Piñas.

PMS is more than an oil change. The visit is used to review maintenance items, fluids, filters and visible wear so the next service decision is based on the vehicle’s actual condition and maintenance schedule.
Check service history, mileage and time based maintenance needs.
Inspect applicable fluids and filters and identify items due for service.
Look at visible brake, tire, underchassis and other wear concerns as applicable.
Separate what is due now from items that can be monitored or scheduled later.
You do not need to know the exact failed part before visiting. The symptom is the starting point for diagnosis.
