How to Make Your Diesel Engine Truck More Fuel Efficient

With the rising fuel prices in recent months, diesel engine truck owners are finding ways to improve their vehicle’s fuel efficiency. Fortunately, doing so doesn’t always involve expensive modifications but rather just some simple tricks that neither cost a dime nor involve some complex instructions.

Does diesel get better fuel efficiency? 

Diesel engines are typically much more fuel-efficient than gas engines, even those with very high compression ratios. Diesel fuel is also more energy-dense than gasoline, meaning more energy per gallon of fuel.

Diesel engines result in little fuel waste because of their efficient combustion process. They also have a higher compression resistance and energy density than other engine types. 

What are tips that can promote better fuel efficiency in diesel engines? 

Even though diesel engines are fuel efficient, there are still some techniques you can do to save money further. 

Continue reading below to learn how to get better fuel mileage in a truck. 

1. Only do modifications that make sense. For example, if you primarily use your diesel truck on highways, you won’t need off-road or mud-terrain tires. Remember, greater traction and lower tire air pressure force your engine to burn extra fuel. 
2. Avoid extended warm-up times. Modern engines don’t need to be warmed up for an extended period of time, unlike older machines. In fact, even on a cold day, most mechanics agree that there is no point in running your engine for more than a minute.
3. Eliminate back pressure. If you have an older truck without any emission components in the exhaust, you can improve its fuel efficiency and horsepower by replacing it with a new system. Visit Choate Engineering Performance to learn more about this modification. 
4. Use your AC sparingly. However, keeping your windows down when you hit the highway creates more drag, which is not really fuel efficient. A good rule of thumb is to keep your windows down while on city driving, then switch to AC on highways. 
5. Practice good driving habits. Avoid high speeds and revving up your engine, accelerate gently, utilize cruise control, and maintain your engine’s sweet spot and run with it are just some of the things you can do to improve your fuel mileage. 
6. Use fuel additives. Not only do they increase your truck’s fuel efficiency, but also its horsepower. Other benefits include:
7. Better lubricity (which means less friction and wear and tear)
8. Reduced carbon emissions
9. A cleaner fuel system (they prevent the formation of algae in your tank)

Final word 

While it’s true that electric/hybrid vehicles are the most fuel-efficient option nowadays, their limited torque and horsepower means that diesel trucks aren’t going anywhere. Remember, no matter how fancy those hybrid and electric vehicles are, their performance is quite limited in hauling and towing heavy loads and traversing challenging terrains.
