DEF Fact or Fiction?
DEF is corrosive, hazardous, and unsafe to handle
Material Safety Data Sheet (MSDS)
• Hazards Identification “Urea Solution is not Flammable”

DEF Fact or Fiction?
Urea becomes toxic at 118°F
“Urea does not become toxic at any temperature”
“…at 122°F, DEF will still meet ISO specifications of less than 0.2% ammonia for at least 35 days. At that rate with would take more than 2 years to reach the ammonia level of household ammonia which is still not classified as toxic”

DEF Fact vs. Fiction
DEF is useless in the cold because it freezes at 12°F
DEF will
start to
freeze at 12°F
Engine coolant is used to thaw DEF in tank. System
will function until DEF begins to flow
EPA Requires DEF flow within 70 minutes – Detroit Diesel testing has proven DEF flow within EPA requirements

DEF Fact vs. Fiction
DEF will cost between $17 and $34 per gallon
$15.50 per Gallon
DEF pricing is dependant on packaging size
Worst Case:Pass Car Dealership
Gallon
Most Frequent Scenario:
Fleet Terminal 275 Gallon IBC
$2.61 per Gallon
$719.60/275 = $2.61/gallon
$7.75*2 = $15.50/gallon

2010 Fact vs. Fiction
“It is generally accepted that a Euro 6
(2013) engine will combine both SCR
and EGR technology.”

Even Europe is moving away from SCR technology
“Euro 6 (2013) limits are almost
certainly going to require EGR
and SCR to share the burden
of NOx control…”
