Diesel Exhaust Fluid

Beginning in January 2010 new EPA regulations regarding particulate, sulfur, and nitrogen oxide (NOx) emissions took effect. One method engine manufacturers have employed to meet the new standard is through selective catalytic reduction (SCR) which requires the use of diesel exhaust fluid (DEF). SCR technology has proven to be highly efficient and studies from major engine manufacturers have shown over a 5% increase in fuel economy when utilizing this technology.

Denny Oil Company is proud to be an exclusive distributor for Yara's AIR1 Diesel Exhaust Fluid. Yara has been a leader in the DEF industry for years in Europe and is now bringing their proven, tested product to the United States for distribution through companies such as Denny Oil Company.
