Diesel Exhaust Fluid (DEF)
Help optimize your diesel-equipped vehicle’s emission system with a visit to Jiffy Lube®. A full DEF tank can help ensure your emission system is working properly.
WHAT WE DO:
When the Diesel Exhaust Fluid (DEF) tank is found to be low on fluid, Jiffy Lube® adds DEF to bring it back to an acceptable level.
HOW IT WORKS:
Diesel Exhaust Fluid (DEF) is an aqueous solution made with 32.5% urea and 67.5% deionized water. DEF is used as a consumable in selective catalytic reduction (SCR) in order to lower NOx concentration in the exhaust emissions from diesel engines.
HOW OFTEN:
Diesel Exhaust Fluid (DEF) service is dependent on many variables, including vehicle load, speed, distance driven and idling time.
Jiffy Lube® recommends following manufacturer recommendations, where applicable, for maintenance schedules and service intervals.
