What is diesel ex­haust fluid?

will re­quire re­place­ment.

On aver­age, a litre of DEF should last about 1000km. How­ever, us­age can be higher de­pend­ing on how and in what con­di­tions the ve­hi­cle is driven. Some ve­hi­cles will have an alert sys­tem to warn the driver when the DEF tank level drops be­low a cer­tain per­cent­age, mak­ing main­te­nance easy. It’s also im­por­tant to note that DEF doesn’t last for­ever and that gen­er­ally it has a two-year life­span from its pro­duc­tion date.

Keep­ing on top of your ex­haust fluid lev­els is cru­cial be­cause ve­hi­cles equipped with an SCR sys­tem can­not op­er­ate with­out DEF.

Fail­ing to keep your ex­haust fluid lev­els topped up can com­pro­mise your ve­hi­cle’s fuel econ­omy and can also cause your car to shut down. So, don’t let your DEF run out or you could find your­self bro­ken down at the road­side — a sit­u­a­tion ev­ery­one wants to avoid.
