Preventive Maintenance
Maintenance built around the truck, not a generic package
STL Diesel does not use one fixed interval for every diesel. Towing, commercial use, extended idling, short trips, dusty conditions and high engine hours can all change what should be inspected or serviced.
Fuel System Service
Fuel-filter condition, water contamination, supply and injector-related concerns are considered along with the manufacturer maintenance schedule.
Cooling System Service
Coolant type, concentration, contamination, hoses, pressure, radiator condition and operating temperature all matter to diesel engine life.
Engine Oil Service
Oil specification and interval should match the engine and duty cycle. High idle time, towing and severe service may justify earlier maintenance.
