Fuel Additives, Are They For You?

Many fleets confess that they use fuel additives from time to time. Most fleets use them in the winter to prevent gelling. A lot of fleets though, regularly treat their fuel with additives of some type. Some use detergent additives or lubricity agents to make up for the loss of sulfur in diesel fuel. Others use fuel stabilizers to offset the effects of aging, and cetane improvers to increase horsepower and reduce emissions.

Many different problems can be solved or avoided when including fuel additives in your maintenance plan, according to Kevin Adams, director of research and development for Lubrication Specialties Inc. By using the correct fuel additives, injector damage due to water and internal diesel injector deposits will be prevented.


When a lubricity additive is used, the life of the injector is increased.


In most cases you will not know if the product is working or not. You would not just tear down an injector to check the condition unless something was wrong. Therefore, honestly how would you know if the problem was caused from the additive or not? In other instances it is easier to tell if a product is working. If your fuel filter plugs, an additive can help dissolve the asphaltenes.

High performance fuel additives can contain ingredients that not only dissolve the asphaltenes that are already present in your fuel, but also help prevent asphaltenes from forming and plugging filters. Many trucks suffer from the effects of a low cetane rating within the fuel that causes poor fuel economy and hard starts during the cold months. A good fuel additive will boost the cetane number and solve each of these fuel related issues.
