How to Make your Diesel Fuel Last Longer in Winter

Hey everyone, this is Kary from Modern Diesel. Since we are slowly gearing up for winter, I want to tell you all about how you can preserve your diesel fuel in winter. As we all know, in the winter diesel has a tendency to become gel-ly and thick so many manufacturers tend to water it down.

In winter, gas mileage becomes lower, so your diesel engine may begin to run slow because the energy produced is lesser. This happens because the diesel has a different blend and it is mixed thinner. Diesel fuel contains about 10 to 20 per cent more energy than the regular fuel used by smaller cars.

Vehicles that have more sophisticated engine functions, use diesel because it is ideal and it provides more energy. So, driving a diesel engine is more efficient but during the colder months you might start to have doubts.

There are a few ways to reduce the effect of the winter season on your truck’s diesel consumption and that’s what I want to share with you today. These tips will help to reduce consumption, but it still can’t be compared to summer, when your fuel lasts much longer. To preserve your diesel fuel and utilize its energy in winter, here are some of the things you can do;

Stock Up on Diesel

I have to start with this point because it is important and it will save you the stress of using diluted diesel. If you’re travelling from a place with warm weather to a location where the temperature is very low, then you might want to fill up your tank before you leave.

Warm places tend to have more normal diesel than places known for their cold weather. Find out what you can about the places you’ll be travelling through, so you’ll know where to buy the best diesel for your truck. You’ll save mileage when you use the diesel that works best for the climate, you’re going to be in.


Diesel fuel may have the best qualities when it comes to driving but in the colder months, the cetane level of diesel decreases, causing it to lose its natural energy. This loss of energy results in lower mileage. Additives can be used to tackle the issue of thinner fuels in winter, you’re probably wondering how.

Additives react with the components of the fuel to reduce any effect lower cetane levels might have in your truck. It also helps with lubricating the injection system of your truck. You might think buying an additive is not worth it, but before you conclude, think about the extra money you would be spending on diesel.

When you consider the extra mileage, you’ll get and the money you’ll save from not buying extra fuel, you’ll see that additives are actually worth it.

Constant Checkups

Regular checks and maintenance can also help you preserve your diesel. Your auto mechanic would know to change to synthetic oils because they flow better in winter. Your tire pressure is another thing you want to pay attention to in colder months because it can either improve or reduce your gas mileage by 1% to 3%.

Winter can be hectic on the road, so take my advice and follow these three tips. If you need any help or have any questions, do let me know.
