DEF Delivery
Reliable Diesel Exhaust Fuel (DEF) Delivery Services
Diesel Exhaust Fluid (DEF) was introduced in the EPA’s 2010 Diesel Emissions Standard. The goal was to reduce emissions of NOx, particulate matter and other pollutants from road vehicles, electric utilities and off-road equipment.
DEF works in conjunction with a Selective Catalytic Reduction (SCR) system to reduce pollution from diesel vehicles and equipment by over 90 percent. SCR systems are active systems and require replenishing DEF on a periodic basis.
Most engine manufacturers have switched to SCR technology, which makes DEF necessary for operating modern diesel engines and equipment. It’s important to maintain proper DEF levels, otherwise trucks and machinery will stop working and could potentially void equipment warranties.

DEF FAQs
What is DEF?
Diesel Exhaust Fluid (DEF) is an emissions-control liquid that’s injected into the exhaust stream but never directly added to diesel fuel. Comprised of a non-hazardous blend of 32.5% urea in 67.5% de-ionized water, DEF is clear and colorless and looks just like water but with a faint smell of ammonia.
What is the freezing point of DEF?
DEF freezes at 12° Fahrenheit.
How do you store DEF securely?
The ideal temperature for storing DEF is between 40-80° F. Keep DEF out of direct sunlight. Its shelf life is up to one year without any issues.
How many miles will one gallon of DEF last?
One gallon of DEF will last between 300 and 500 miles.
What happens if I run out of DEF?
Most manufacturers of diesel vehicles and machinery have added instrumentation such as DEF gauges, indicators and dashboard displays. IF DEF is not refilled in time, your vehicle or machinery will go into “limp” mode and experience a drop in performance until you refill the DEF.
What year vehicles require DEF?
Almost all diesel-powered vehicles manufactured since 2010 are equipped with SCR systems and require DEF.
