Motor off. Keep it like that — no second on, no shifting it at all. The coming few minutes decide it far more than anything else: petrol in a diesel that has not run generally comes down to clearing and purging, on the spot. Anywhere you happen to be in Northdown, here is how things run from here. ## Minute one: petrol in a diesel, engine off Go through these in sequence, first. - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of your tank towards the components it damages. - A bigger tank of the same mixture is all topping up leaves you, because it takes out nothing. So no extra diesel. - Being seen comes first near moving traffic: put the hazard lights on, and only then think about anything else. - However short the distance, starting it to shift it is the thing to avoid. At a forecourt, push the car away from the petrol pump by hand instead, and ask the attendants to lend a hand. - Hold on to the till receipt: the fuel and roughly how much are written on it, and they are what we ask about first. Realised on the move? Get off at the next junction if you are on the M2, under 25 miles from Northdown, and pull over somewhere safe — not at the services further on. Stage one starts after that. ## Northdown fuel drain: has the motor run yet, or not? What comes next rests on one answer, and just one. Not run, not even once: - The petrol remains inside the tank, and just there. - Where the car sits is usually where this work is done: a drain, then a flush. - This is as good as it gets — which is the entire point of stage one. If the engine has been run, even for a moment: - Some petrol has left that tank already, passed through the filter, and got into the fuel lines. - The high-pressure pump and your injectors get it on a longer run. - Flushing the lines, the fuel filter dealt with, occasionally more: this job expands as the mileage does. That line falls there since diesel lubricates the high-pressure fuel pump and your injectors on its way through them — and petrol doesn't. In that tank, sitting still, petrol does no harm. Petrol being pumped is grinding down the components that shift the car. ## Northdown, petrol in a diesel: have these prepared before you call Prepare a little, and the van finds you instead of circling. - CT9 3 plus the remainder of the postcode makes the ideal way to begin telling us where you are. - A road name is a help: St. Mary's Avenue, say, or whichever street you've stopped in. A car park does the trick too. - Name a car park by what it serves — the one at Tesco, for example — and it's far easier to find. - Say what your car is — make, model — and check it is diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Northdown page. - How much. Litres from your receipt, or how long the nozzle was in. - If it's run, how far plus how heavily — as well as if it has run at all. - Whose vehicle it is. Some hire and company contracts want the owner to authorise the work, and that's easier settled before we get there than after. Next, 0333 366 0103. Not time-critical, your car left at home with nowhere to be? Then works as well. ## Waiting for a fuel drain around Northdown: what to do Help, however well meant, is what does the harm whilst you wait. So hold to these. - Wait with the vehicle if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - Additives remain in your boot. Injector cleaner and two-stroke oil take none of that petrol out again. - A DIY drain misses your fuel already gone beyond the tank, and siphoning petrol by the road is dangerous besides. - Even the radio or your windows are not worth turning the ignition on for. ## When our van arrives: your fuel drain, step by step - Three questions. What got in, how much, and whether it has run. The replies decide the job, which is why the quote comes after them and not before. - Draining it is how the mixture gets taken from that tank. - Your lines are purged. If it ran, that petrol has moved beyond your tank, and the lines are carrying it. - Cleaned, or swapped if your car has a workable one: the fuel filter is dealt with next. - Clean diesel goes in, and the system is primed. - Our engineers start it only after new diesel has gone in and bled the fuel system, then confirm that it's running smoothly. Only once it's running on new diesel do our engineers leave. If it has been caught soon, lasting damage is very rare, and the car returns to normal use at once. ## Back on the road around Northdown after the fuel drain - Once it's been started on fresh fuel, there's nothing special to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over and ring us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Northdown itself Northdown is a suburban area in Kent, situated on the coast near the towns of Cliftonville and Kingsgate.
