Diesel Fuel Additives and Fluids for Your Car


Diesel fuel additives are an important part of maintaining a diesel-powered vehicle. Diesel vehicles have come a long way, but diesel can still cause buildup in your engine. Using a diesel fuel additive can help clean away gunk and lubricate the vital parts of your engine.


When it comes to automotive upkeep, you need to do more than change your oil and get an occasional car wash. The correct fuel additive can help to ensure that your diesel fuel doesn’t change viscosity, or thickness, when the temperature drops in winter.


Gas-powered vehicles won’t need gas treatments as frequently as diesel vehicles need treatments. Adding gas treatments a few times a year or based on the mileage you put on the vehicle is still a good practice.


Frequently Asked Questions


Q: Are diesel fuel treatments necessary?

A: Yes, diesel mechanics recommend diesel fuel treatments on a regular basis. While diesel fuel engines burn much more cleanly than they used to, the combustion process can still leave a residue. Diesel also contains paraffin, which can turn into a gel in cold temperatures — something you want to prevent. Fuel additives can help clear residue and prevent your diesel fuel from congealing.


Q: How often should I use diesel fuel treatment?

A: It’s good to use a cetane booster to lubricate your engine every time you fill the gas tank, as well as anti-gel treatments to prevent the fuel from reacting to low temperatures in the winter. You should use diesel fuel treatments year-round to keep your vehicle running well.


Q: How often should you use fuel additives?

A: Generally, you should use fuel additives, such as fuel injector cleaners, after every 3,000 to 5,000 miles that you drive.
