How To Get Better Mileage From Your Diesel Engine

We know you want to get the most miles possible out of your diesel engine!

Diesel engines have a reputation for being powerful and having great fuel economy. However, you might want to spend as little time as possible at the pump. Thankfully, with a little care and attention, you can make every drop of diesel count!

Owning a diesel vehicle can be a double-edged sword. On one hand, it has great durability and performance. On the other, fuel efficiency concerns many drivers. If you’re looking to stretch every drop of diesel for your vehicle, you’re in the right place. Here are some tips on how to get better mileage from your diesel engine so you spend as little time as possible filling up the tank.

Choose the Right Diesel Fuel Additives

Choosing the right fuel additives can make a huge difference to your vehicle’s fuel efficiency. Additives that lubricate the engine, such as cetane boosters and fuel stabilizers, can lead to smoother operation, better combustion, and improved mileage.

Avoid rail-specific detergents and additives that may not be compatible with your diesel engine. When in doubt, you can always check your car’s manual to see what additives the manufacturer recommends.

Keep the Fuel Injectors Clean

Dirty fuel injectors can cause uneven fuel distribution, inefficient combustion, and an increase in fuel consumption. Luckily, you can clean your fuel injectors with DIY injector cleaner or professional high-pressure cleaning services. Some signs of clogged diesel fuel injectors include decreased fuel economy, so getting those cleared out can make a noticeable difference in your mileage.

Regular cleaning or professional servicing can restore your injectors to optimal condition and potentially save you money on fuel in the long run.

Replace Your Air Filters Regularly

Diesel engines require a lot of air to mix with fuel for combustion. Clogged or dirty air filters can restrict airflow, leading to a poor mixture that burns more fuel than necessary. Replacing your air filters according to manufacturer guidelines can lead to noticeable improvements in fuel economy. Don’t forget to check the cabin air filters, as well! Those filters are essential for your comfort and can hinder engine performance if clogged.

Improve Your Driving Habits

Another way to get better mileage from your diesel engine is to pay more attention to how you drive. Avoid instantaneous acceleration, particularly when the engine is cold. This behavior can waste fuel. If you drive a manual, utilize your vehicle’s high torque at low RPMs by shifting gears early and maintaining a consistent and moderate speed. In stop-and-go traffic, leave enough space behind the vehicle in front of you to anticipate abrupt stops and avoid unnecessary acceleration.

Classic cars with diesel engines are great vintage items that can increase in value over time, but only if you take good care of them!

By incorporating these tips into your diesel vehicle maintenance routine, you’ll likely see an improvement in fuel economy. With a little extra care and attention, your diesel engine can take you the extra mile—literally!
