Diesel exhaust fluid (DEF) is an important component of diesel engine technology. It helps reduce emissions of nitrogen oxide (NOx), which is a major contributor to air pollution. While DEF is used in many diesel vehicles, choosing the right product can be difficult. This article will provide an overview of the benefits of using DEF, the types available, and the factors to consider when choosing a diesel exhaust fluid. It will also discuss the top-rated DEFs on the market and provide tips for using them correctly.
What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid (DEF) is a urea-based liquid solution that works in conjunction with diesel engines to reduce emissions of nitrogen oxide (NOx), a major contributor to air pollution. DEF is used in diesel-powered vehicles to meet the standards set by the Environmental Protection Agency (EPA). DEF is stored in a separate tank from the diesel fuel and is injected into the exhaust stream to reduce NOx emissions.
Benefits of Using Diesel Exhaust Fluid
Using DEF can have many benefits for diesel engine owners. It helps to reduce emissions of NOx, helping to improve air quality. It can also improve fuel economy and engine performance, resulting in lower fuel costs. Additionally, DEF helps to extend the life of a diesel engine by reducing wear on engine components.
Types of Diesel Exhaust Fluid
There are two main types of DEF available: conventional and synthetic. Conventional DEF is made from pure urea and is the most common type of DEF. Synthetic DEF is composed of a blend of urea and other chemicals, which makes it more stable and less likely to degrade over time.
Factors to Consider When Choosing a Diesel Exhaust Fluid
When choosing a DEF, there are several factors to consider. First, consider the type of DEF needed. Conventional DEF is usually the least expensive option, but synthetic DEF may be more stable and provide better performance. Additionally, consider the size of the DEF tank and the amount of DEF needed. Some DEFs come in large containers, while others are available in smaller quantities. Finally, consider the manufacturer’s reputation and the quality of the DEF.
Top-Rated Diesel Exhaust Fluids
Some of the top-rated DEFs on the market include: Shell Rotella T6 5W-30 Synthetic Diesel Engine Oil, Valvoline Premium Blue DEF, and Chevron Delo DEF. All of these DEFs are formulated to meet the EPA’s standards for NOx emissions
