Diesel Maintenance: The Key to Long-Term Reliability

Scheduled oil and filter changes
Transmission and differential fluid services
Air, fuel, and cabin filter replacements
Glow plug and battery inspections
Brake checks and suspension evaluations
Coolant flushes and thermostat replacements

Tire rotation and pressure checks

At 1E Diesel, we tailor maintenance schedules based on how you drive—whether that’s heavy hauling, daily commuting, or a combination of both.

If you want to unlock your truck’s full potential, diesel tuning is the answer. At 1E Diesel, we offer performance tuning solutions that are safe, effective, and tailored to your goals—whether it’s more torque, better MPG, or smoother towing.

Diesel tuning services include:

ECM tuning for better throttle response and drivability

Fuel mapping for enhanced economy and reduced emissions
Custom tuning packages for performance upgrades

Our tuning services are performed with reliability in mind—so you get more from your truck without sacrificing longevity.
