Improving the Air Today for a Better Tomorrow

Santmyer Oil's Diesel Exhaust Fluid (DEF) helps you reduce emissions as well as your fuel costs. We are fully equipped to meet all of your diesel exhaust fluid needs while making a positive impact on your bottom line and our environment.

Santmyer Oil provides the highest quality DEF services at competitive prices with on-time custom delivery to keep your engines running smoothly and responsibly.

Better still, diesel exhaust fluid helps you save money with your Selective Catalytic Reduction (SCR)-equipped diesel vehicles over every mile driven every day. Trucks averaging 7 mpg will have an average 4 percent improvement in fuel economy that results in hundreds of dollars in savings annually.

Santmyer Oil's Diesel Exhaust Fluid is designed specifically for reducing NOx emissions in (SCR)-equipped diesel engines. It converts exhaust to harmless nitrogen and oxygen and helps your trucks run cleaner for a healthier environment.

The urea-based DEF is an easy-to-use product that meets ISO22241 specifications. It is non-toxic, non-flammable, non-hazardous and colorless. View our Material Safety Data Sheet and our DEF usage table for more product and manufacturer information.

API Certified      

Santmyer Oil's diesel exhaust services are American Petroleum Institute (API) certified. The API Diesel Exhaust Fluid Certification Program is a voluntary program that certifies and monitors the quality of diesel exhaust fluid intended for use in SCR-equipped cars and trucks. The program was designed to help consumers locate DEF that meets diesel engine manufacturer requirements.

Diesel exhaust fluid marketers, like Santmyer Oil Company, that certify their DEF meets the performance requirements developed by diesel engine manufacturers, may be licensed by API to display the API Diesel Exhaust Fluid certification mark. This mark identifies fluids meeting the performance requirements for proper SCR operation.

Santmyer Oil also provides branded fuel programs, wholesale fuels, lubricants, and commercial fuel management.
