Wrong Fuel Emergency – More Adblue Blues

Wrong Fuel EmergencyMany diesel vehicle drivers, especially those driving diesel vehicles for a living will be well aware of Adblue at this point in time. Adblue is a diesel fuel treatment that helps convert a lot of the bad nitrous oxide emissions from a diesel exhaust system, into nitrogen and water (in steam form). Many diesel vehicles have a separate Adblue tank which holds a few litres of Adblue and will last for quite a while, depending upon how many miles you do. We have previously posted about Adblue on our blog concerning the dangers of accidentally putting Adblue into the diesel fuel tank. As mentioned, some vehicles have the Adblue and fuel tank apertures close together and at some fuel stations the nozzles for diesel and for Adblue are the same colour. Mistakes are quite easily made in these situations. The reason we are posting again on this subject is to warn diesel drivers who have been recently introduced to Adblue, against bad advice which seems to be in circulation. Just like the wrong fuel bad advice suggesting that it’s OK to run your diesel vehicle if you’ve accidentally put a few litres of petrol into the tank, as long as you top up with diesel (very bad advice, please don’t try this), there seems to be another rumour mill running somewhere suggesting that it might be a good idea to put some Adblue in with your diesel! No,no,no! This is terrible advice but it has obviously been doing the rounds as we have had a number of call outs now to workshops where a vehicle has been brought in with various running complaints and the mechanic has deduced that there is something wrong with the fuel which has caused an engine issue.

Very often the first question we ask in these cases is, “Has the driver put the wrong fuel in the tank and tried to drive the vehicle in this condition?” and often, we get a positive response. But in a few cases the mechanic has discovered that the driver was advised by a friend/colleague/bloke down the pub, that they should put some Adblue into the diesel tank to further reduce emissions levels. The reason that this is a terrible idea, as we have discussed before, is that Adblue is corrosive and whilst that may not affect your plastic fuel tank, it will most certainly not be good at all for the metal components in your diesel vehicle fuel system and engine. Adblue and diesel fuel must always be kept in their separate tanks and never mixed. The Adblue is introduced to the exhaust system close to the exit point of the hot harmful gases and in such a way that it affects the emitted gas only and not the metal of the exhaust system.

If you suspect a vehicle may have Adblue in its fuel tank or if you own a vehicle and have followed some bad advice and introduced Adblue to a diesel vehicle fuel tank, please call a member of our expert wrong fuel emergency team who will be able to come straight out to you and perform a fuel drain on your vehicle.
