Usually, if your motor has not turned, it is emptied and fully rinsed where your vehicle is around Perry Street. The remainder of this page explains why it takes place and how to make sure it doesn't — handy if you are reading before it has happened.

AdBlue in a diesel motor, and its separate tank

Plenty of newer diesels on the roads about Perry Street and Wombwell Park carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

There's a filler for each tank. Many of motors share a single flap for the two, whereas others put the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. Seldom topped up, AdBlue usually comes from a bottle, tipped by someone who must stop and think which cap to use. It's in the gap that the slip lives.

How does AdBlue in the diesel tank take place in Perry Street?

It is rarely carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Park Avenue before work, or in the car park outside The Campbell Arms on the way home.

Then the vehicle is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one.

A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, once started, keeps on. The same few seconds decide it, in the middle of Perry Street or out in Northfleet.

The AdBlue filler and your diesel filler: telling them apart

Check these first, on a forecourt in Perry Street or a driveway out in Gravesend. Seconds, that's all.

  • Check the cap instead of going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones usually aren't.
  • On plenty of cars, size tells: AdBlue has the smaller filler neck.
  • Open the flap and look for a label — many vehicles show which goes in which inlet just there.
  • The handbook says which it lives if the filler isn't next to your diesel cap: the boot, or under the bonnet.
  • Picking up a hire or company car, say at the car park outside Gravesend? Ask the person who drove it last before leaving, not once the light goes on.

How to top up without AdBlue in the diesel tank

Anywhere around Kent the light comes on, this is a routine for that day.

  • Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Dover Road East.
  • Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud while you unscrew it. It seems daft. It works.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Stop once the tank fills or the bottle is empty; before that, tip gently through the built-in spout.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

If at step two or three you find you have already poured into the diesel side, stop there. Never go on to stage five.

Perry Street: already put AdBlue in the diesel tank?

Then the order of things is short. Do not start the engine. The fuel pump starts on plenty of diesels the moment your ignition is switched on — and so keep it off. Thinning it with extra diesel fails, since AdBlue sinks to the base rather than blending — and that is where your fuel is sucked from.

On a forecourt — Texaco, Esso or another — the attendants will normally help push the car clear, when you ask. Your own drive in Perry Street is the place it stays.

Stop as soon as it is safe and switch off, if the motor has already run. Perry Street lies under 5 miles from the M2; there, take the next junction. Roughly how far did it go? Hopping across Perry Street is smaller work than a run of under 25 miles to Southend-on-Sea, and so tell us.

When our technicians arrive around Perry Street, what occurs?

Outside Copperfield Academy, near All Saints Church or on your own drive: wherever the vehicle has stopped, our technicians come to it. Both the work and our quote depend on three replies — what liquid, what amount, and whether it's run — so our technicians ask. You get that price on the phone, before anybody heads out.

The system is then flushed thoroughly, after that tank is cleared. More than with petrol, it counts here: the crystals form, some metals are attacked, and nothing washes out on its own, no matter how long it sits. Testing is last: before that, clean diesel is added, and the fuel filter is cleaned or changed as needed. Your engine is started next and checked to confirm it runs properly, all before our technicians go.

Unstarted vehicles mostly need a half-hour visit from the moment we arrive. The equipment is safe on a busy forecourt, and hushed enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy as the van travels to you: misfuelling cover comes with plenty of policies.
