1. Use the correct fuel. Diesel engines require a specific type of fuel, so make sure you're using the correct one. Using the wrong fuel can damage your engine and reduce your fuel economy.
2. Keep your engine tuned up. Regular maintenance, such as oil changes, air filter changes, and tune-ups, will help keep your engine running efficiently and getting the best possible mileage.
3. Drive smoothly. Accelerating and braking quickly can waste fuel. Instead, try to drive smoothly and gradually accelerate and brake.
4. Use cruise control. Cruise control can help you maintain a consistent speed, which can improve your fuel economy.
5. Avoid idling. If you're going to be stopped for more than a minute or two, turn off your engine. Idling wastes fuel and can also damage your engine.
6. Check your tire pressure. Underinflated tires can reduce your fuel economy. Make sure your tires are inflated to the correct pressure, which can be found on the sidewall of your tires.
7. Remove any unnecessary weight from your vehicle. Extra weight can reduce your fuel economy. If you don't need something in your vehicle, take it out.
8. Drive in the correct gear. Driving in the wrong gear can waste fuel. For example, if you're driving in too low of a gear, your engine will have to work harder and use more fuel.
9. Plan your trips ahead of time. By planning your trips ahead of time, you can avoid traffic congestion and stop-and-go driving, which can both reduce your fuel economy.
10. Use biodiesel. Biodiesel is a renewable fuel that can be used in diesel engines. It is made from plant-based oils and can help improve your fuel economy and reduce your emissions.
