Diesel Exhaust Fluid (DEF)

Keep your fleet stocked with DEF from Quarles.

DEF is a solution sprayed into the exhaust stream of diesel vehicles to break down noxious emissions into nitrogen and water.

DEF is required in most new trucks, buses, and coaches.

When it comes to keeping your fleet stocked with DEF, Quarles has you covered.

DEF is available at several Quarles Fleet Fueling sites and delivered to your location packaged or in bulk.
