Engine off. Leave it that way — no moment on, no shifting it anywhere. Emptied then rinsed, right where it sits: that is normally all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes ahead more than on anything else. From now on, in order, for anywhere in Broxbourne: ## Minute one: petrol in a diesel, motor off In this sequence, and before anything else: - Ignition off, keys out. Switched on, your ignition can prime the system — and priming is what moves petrol out of the tank towards the parts it damages. - No diesel on top. More fuel in takes away none of that petrol — it just leaves you with extra of the same blend. - Hazards on. If you are anywhere close to moving traffic, make the vehicle easy to see before you do anything else. - Off the pump by hand. At a forecourt, get the staff to help you roll it away from the petrol pump. Don't crank it to shift it, however short the way. - Hold on to your receipt: the fuel and roughly how much are printed on it, and they're what our technicians ask for first. On the M25, under 5 miles from Broxbourne, the next junction is the spot to come off; elsewhere, the first sensible place to stop. Don't push on to the services. Then go back to stage one. ## Every Broxbourne fuel drain starts here: has your engine run? One answer is what everything after this point rests on. Not run, not even once: - Only the tank has petrol in it for now. - The job is a drain and a flush, usually done where your car stands. - Being here is the best case — which is the whole point of stage one. Motor run, even for a moment? - Petrol has been pulled out of the tank, past the fuel filter then into your lines. - Run it further and that petrol reaches the fuel injectors, having passed through your pump first. - The farther it went, the bigger the job — your lines, the filter, and now and then more besides. Petrol doesn't lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line sits where it does. In the tank, left alone, petrol harms nothing. As soon as it is pumped, petrol starts grinding whatever moves it. ## Broxbourne, petrol in a diesel: have these prepared before you call Prepare a little, and the van finds you rather than circling. - Your whereabouts: a postcode beginning EN10 7 works best. - A road name is a help: Sawells, say, or whichever street you've stopped in. A car park works too. - Or the landmark. A car park is easier to find by what it serves, such as the one outside Iceland. - That it's a diesel, plus the make and model of the vehicle. - Say which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Broxbourne. - How long the nozzle was in, or the litres from your receipt — either tells us how much. - Whether it's run. Then if it has, how far plus how hard. - The owner may have to approve the work under some hire or company contracts — so it's quicker to settle whose motor it is before our technicians get there. Ring 0333 366 0103 next. Writing to is fine too if it can wait, with the vehicle parked at home, going nowhere. ## The wait for a Broxbourne fuel drain, and what to do in it In the wait, the harm comes from well-meant help — so these count. - Stay with your car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one — however kind — starts it, whether to see if it runs or to move your car a short way. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it gets that petrol back out. - No DIY clearing. Siphoning petrol into a can at the roadside is hazardous, and it leaves your fuel that has already gone beyond the tank. - The ignition remains off. Even for your radio or the windows. ## The fuel drain, step by step, after our van arrives - Our price comes after three questions, not before them — what went in, how much, and whether it's run — because the answers set the job. - Clearing it's how that mixture gets taken from the tank. - The fuel lines are purged. If it ran, that petrol has shifted beyond the tank, and the fuel lines are holding it. - Cleared, or replaced if the vehicle has a workable one: the fuel filter is dealt with next. - Clean diesel in, and the fuel system primed. - First start on new diesel. Once priming is complete, your engine is fired up and our engineers confirm that it runs properly. Until it runs on clean diesel, we remain with it. Long-term damage is very uncommon when it has been noticed early, so the car can go straight back to normal driving. ## Broxbourne, after your fuel drain: back on the road - Started on clean diesel, it needs nothing special of you. Just drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then ring us back. - The work may come up later with a hire company, an insurer or a fleet manager. Hold on to your paperwork. - Next time, check the pump. The label, not the colour of its handle. ## About Broxbourne and where it is Broxbourne is a suburban area in Hertfordshire, situated on the River Lea at an elevation of 37 metres.
