With proper care, a diesel engine can last hundreds of thousands of miles—more than double the lifespan of a gasoline engine!
1. Regular Oil Changes
- Why it’s important: Diesel engines run under more stress than gasoline engines, so keeping the oil fresh is crucial to protect key components.
- Expert Tip: Use high-quality oil. Follow the oil change intervals to avoid carbon buildup and premature wear.
- Additional Tip: Don’t just change the oil—get a multipoint inspection and stay ahead on future repairs like brakes and maintenance items. Air filters are vital when it comes to fuel economy and power. You can always upgrade to one of our cold air intakes and increase power and fuel economy.
2. Monitor and Maintain Cooling Systems
- Why it’s important: Overheating is a major cause of engine failure, so a properly functioning cooling system is vital.
- Expert Tip: Check the coolant level and condition frequently, especially before long drives. Flush the cooling system every 2-3 years.
- Additional Tip: Make sure the radiator is free of debris, and inspect hoses and clamps for leaks or signs of wear.
3. Fuel System Maintenance
- Why it’s important: Diesel engines rely on the fuel system’s efficiency, including the fuel injectors and fuel filters.
- Expert Tip: Replace fuel filters as recommended by the manufacturer. Clean injectors regularly to avoid clogged nozzles and reduced fuel efficiency with any of our top fuel injector cleaning additives. Hot Shot Secret offers one of the best fuel additives and you can always pick one up at our store.
- Additional Tip: Always use clean, high-quality diesel fuel. Or upgrade your fuel system to a Fass Fuel System that will deliver optimal clean fuel and get rid of 99% of air from your fuel system that can also increase your fuel systems life!
4. Inspect the Air Intake System
- Why it’s important: A clean air supply is essential for proper combustion and engine performance.
- Expert Tip: Replace the air filter regularly to ensure smooth airflow. A clogged air filter can lead to reduced fuel efficiency and increased engine wear.
- Additional Tip: Check the intake hoses for leaks or cracks that could allow dirt or water into the engine
5. Drive Smoothly and Avoid Overloading
- Why it’s important: Hard driving conditions, like frequent heavy acceleration, excessive idling, or carrying too much weight, can place unnecessary strain on the engine.
- Expert Tip: Drive smoothly, and avoid rapid acceleration or heavy braking whenever possible. Avoid idling for long periods.
- Additional Tip: Don’t overload your vehicle beyond its rated capacity, as this can strain the engine and other components.
6. Monitor Exhaust System Health
- Why it’s important: Diesel engines produce higher emissions, so a healthy exhaust system ensures proper exhaust gas flow and reduces engine strain.
- Expert Tip: Regularly check for leaks, rust, or cracks in the exhaust system. If the exhaust system isn’t functioning properly, it could lead to a host of problems, including poor engine performance.
- Additional Tip: Keep an eye on the diesel particulate filter (DPF) fluid. Making sure you complete and regeneration completely while driving can avoid DPF failure and also excessive regenerations.
7. Keep an Eye on Engine Diagnostics
- Why it’s important: Modern diesel engines come equipped with diagnostic systems that can alert you to potential problems before they become major issues.
- Expert Tip: Pay attention to warning lights or unusual sounds and vibrations. Have the engine scanned for error codes regularly to catch issues early.
- Additional Tip: Use high-quality diagnostic tools to help you monitor critical engine parameters like fuel pressure, exhaust temperature, and turbo performance. Most trucks already have all these monitors on their dash.
By following these expert tips, your diesel engine can keep running strong for years to come—saving you money and maximizing performance!
