DEF – Formulated using only high-purity urea and
pure water.  It is approved for use in all SCR-equipped cars,
trucks, and power generators.  Directions
for use – Certified DEF comes pre-diluted with pure
water so no mixing is required.  Never top off your DEF tank
with water alone.  Do not mix Certified DEF with diesel fuel.
 Avoid contamination by using a dispensing spout or funnel for
DEF only. Service
Interval – DEF consumption rates vary by equipment
and duty cycle.  Use the DEF Consumption Chart below
to estimate usage for your vehicle.
