Adblue how does it work

And the name? Diesel vehicles offer strong performance, but the downside is that they emit more cancer-causing nitrogen oxide than petrol engines.

Use of AdBlue has been common on trucks and buses since following the introduction of Euro4 regulations for those vehicle classes. AdBlue is considered a consumable similar to fuel. AdBlue must never be added to fuel. AdBlue is always stored in a completely separate tank. However, in many vehicles the AdBlue filler will be located next to the fuel filler.

It should also be noted that any damage incurred through the misuse of AdBlue such as adding it to either petrol or diesel tanks, or a breakdown resulting from low AdBlue levels, will not be covered under maintenance or recovery arrangements.

Maintained leasing contracts do not cover AdBlue costs. However certain lease providers will top up AdBlue as part of a routine service. Drivers should make themselves aware of their responsibilities by consulting their vehicle handbook. If you liked this article then check out our posts about similar topics.
