Here Is What Happens Pause, and leave the engine off — not on, and not for a moment to move it. Petrol in a diesel that has not been run is generally a simple drain plus a flush, done right where the vehicle stands, and what happens in the coming few minutes determines that more than anything else. Anywhere you are around Hady, here is how things go from now. ## Minute one: petrol in a diesel, motor off In this sequence, and before anything else: - Bleeding the fuel system draws petrol from your tank towards the components it harms, and switching your ignition on can be enough to do that. So the keys come out, and your ignition stays off completely. - Topping up with diesel seems like it thins the trouble. It does not: nothing comes out, and your tank just holds more of the same. - Close to moving traffic? Then your hazards go on before anything else, so the vehicle is simple to see. - However short the distance, starting it to move it is the thing to avoid. At a forecourt, roll the vehicle away from the pump by hand instead, then ask the staff to help. - The first thing you will be asked is which fuel you put in and about how much — and your receipt shows both. Hold on to it. If you were still on the move when you noticed, stop somewhere safe instead of pushing on for the services — on the M1, under 3 miles from Hady, that means the next exit. Stage one comes next. ## The fork in every Hady fuel drain: has it run yet? What comes after this rests on one answer, and just one. If it has never been started: - The petrol remains inside your tank, and only there. - A drain and flush, on the spot, is usually the whole job. - This is as good as it gets — which is the entire point of step one. If the engine has run, even for a moment: - Petrol has been pulled out of the tank, through your filter then into the fuel lines. - A bigger run takes it all the way to the high-pressure pump and the fuel injectors. - The job grows with the mileage — lines flushed, filter sorted, occasionally more. Why the line falls there: diesel lubricates the high-pressure fuel pump and the injectors as it passes through them, and petrol does not. Nothing is damaged by petrol that's only waiting in a tank. The parts that move it are grinding the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Hady Whether the van circles or finds you depends on a little preparation. - S41 0 and the remainder of the postcode is the best way to begin telling us where you are. - A road name is a help: Houldsworth Drive, say, or whatever street you've stopped in. A car park works too. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one outside The Co-operative Food. - That it's a diesel, along with the make and model of your car. - Which went in counts: AdBlue is a separate job from petrol, plus Hady has a page just for that. So tell us. - How much. Litres from your receipt, or how long the nozzle was in. - Has it run? If so, tell us how far it went, and the way it was driven. - The owner may have to authorise the work under some hire and company contracts — which is why it is faster to settle whose car it is before our engineers get there. Next, 0333 366 0103. Not urgent, the car left at home with nowhere to be? Then works as well. ## While you wait for a fuel drain around Hady Hold to these: well-meant help does the harm during the wait. - Your safety comes before your car. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it stands? Stay with it. - A kind passer-by does not crank it. Nor does anyone checking it still works, or rolling it a few yards. - None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - Siphoning petrol into a can by the roadside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Do not drain it yourself. - Even the radio or the windows aren't worth turning the ignition on for. ## Step by step: your fuel drain when our van arrives - Three queries. What got in, how much, and whether it has run. Those replies decide this job, which is why our price comes after them and not before. - Clearing it is how the mixture gets taken out of the tank. - Petrol that has shifted beyond the tank sits in the fuel lines if it ran, and your lines are flushed to clear it. - Then the fuel filter: swapped where there is a usable one, cleared where there is not. - Your system is primed with clean diesel. - Starting it. When the fuel system is bled with clean diesel, we start it and make sure it runs properly. Our technicians wait until it is running on new diesel. Your car goes back to normal driving right away, and long-term damage is very rare if it has been noticed quickly. ## Hady, after the fuel drain: back on the road - Started on fresh diesel, it needs nothing unusual 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. Keep the documents. - Read the label on the pump next time, not the colour of its handle. ## About Hady Hady is a suburban area in Derbyshire, situated on the riverside at an elevation of around 135 metres.
