Getting the most out of a diesel engine's fuel efficiency is top of mind for owners and drivers of diesel-powered vehicles. We will share the best ways to improve the gas mileage of your diesel engine so that you can enjoy long drives and reduced fuel costs. From regular maintenance to driving habits, these techniques will help you achieve great performance from your diesel engine.
Keep Up With Regular Maintenance
Taking good care of your diesel engine is a significant step toward improving fuel efficiency. A well-serviced engine operates efficiently and consumes less fuel than a neglected engine. Regular oil changes with high-quality oil are vital for keeping the engine's parts moving smoothly. Similarly, clean air and fuel filters can prevent unnecessary fuel waste, so clean or replace them when changing the motor oil.
Timely replacement of worn-out parts, particularly fuel injectors, can also contribute to better fuel economy. Regular maintenance not only improves gas mileage but also extends the lifespan of your diesel engine, so make sure to follow your vehicle manufacturer's recommended service intervals for the best results.
Choose High-Quality Fuel
One of the best ways to improve the gas mileage of your diesel engine is to upgrade the type of fuel you put into it. Using high-quality diesel can significantly enhance your vehicle's performance and fuel economy. High-quality diesel contains fewer impurities than low-grade fuel, which means it burns cleaner. This results in less engine wear, greater longevity, and less maintenance.
High-quality diesel fuel often contains additives that can enhance engine performance. These additives clean and lubricate the engine while improving fuel efficiency. Though premium diesel might cost more than standard diesel, these long-term benefits can save you money in the long run. If you are unsure what type of fuel your diesel engine can handle, we recommend contacting a professional mechanic or consulting your engine manufacturer’s manual.
Monitor Tire Pressure
Keeping an eye on your vehicle's tire pressure can also play a significant role in improving fuel efficiency. Under-inflated tires increase rolling resistance, which makes the engine work harder and consume more fuel to move the car at any given speed. On the other hand, over-inflated tires can lead to an uneven wear pattern and decreased traction, both of which can negatively affect fuel economy.
Maintaining the optimal tire pressure is a delicate balance that can significantly improve your vehicle’s gas mileage. Check the tire pressure at least once a month, and adjust it according to your vehicle manufacturer's recommendation. Appropriate tire pressure contributes to better fuel economy and extends the lifespan of your tires.
Limit Excessive Weight
Excessive weight is another factor that can reduce your diesel engine's fuel efficiency. The heavier the vehicle, the more energy it uses to move, which requires more fuel. It's not uncommon for diesel truck owners to carry heavy equipment, tools, or other items in their trucks because diesel engines are great for vehicles that haul heavy cargo. However, unnecessary weight, such as unused equipment collecting dust in your truck bed, can take a toll on your fuel economy. Consider removing any non-essential items to reduce the overall weight of your vehicle. Remember, every pound counts when it comes to fuel efficiency!
Reducing the weight of your truck can result in surprising improvements to your diesel engine's gas mileage. It's worth noting that a lightweight vehicle is generally safer to drive and puts less strain on the engine, brakes, and suspension. Keeping your vehicle's load weight within the manufacturer's recommended limit is crucial for optimal fuel efficiency and great vehicle performance.
Install Aftermarket Performance Parts
Another effective method to enhance fuel economy is by installing aftermarket performance parts. They can improve the functions of your diesel engine and potentially enhance fuel economy. For instance, performance air filters allow more air to flow into the engine, improving combustion efficiency and leading to better gas mileage. Performance exhaust systems can also improve fuel economy by reducing exhaust back pressure and increasing engine efficiency.
Performance chips and programmers offer customizable settings that help the engine optimize fuel-air mixture, shift points, and other variables. Keep in mind that not all aftermarket parts will guarantee an improvement in fuel economy. Some components may increase power at the expense of fuel economy. Consult a professional mechanic or your vehicle's manufacturer before making any significant modifications to the engine in order to make sure they won't adversely affect your vehicle's warranty or performance.
Invest in Synthetic Engine Oil
One of the most effective ways to maximize the performance and fuel efficiency of your diesel engine is by investing in synthetic engine oil. Compared to mineral oils, synthetic oils provide superior lubrication, reduce friction, and withstand higher temperatures. This results in smoother engine operations, reduced wear and tear on engine parts, and improved fuel economy!
Synthetic engine oils are resistant to thickening, so they will continue to flow smoothly even in cold climates. This can be especially beneficial for diesel engines subjected to heavy-duty use in harsh conditions. Finally, synthetic oils tend to last longer than mineral oils between changes, contributing to their cost-effectiveness.
You should always refer to your vehicle's owner's manual before switching to a synthetic oil, as some diesel engine models have requirements for the oil they can take. Still, investing in synthetic engine oil can upgrade the overall performance of your diesel engine, namely improvements in fuel economy.
