Pause there. Petrol in a diesel that has not been run is normally a simple drain and a flush, done where your vehicle stands, and what happens in the coming few minutes decides that far more than anything else. What follows is the sequence from here, anywhere in Hallam Head you are. ## Petrol in a diesel, engine off — the first minute First, these — in this order. - Pull the keys out. Even the ignition on its own can prime your fuel system, drawing petrol out of the tank to precisely the components it harms, and so leave it alone completely. - No diesel on top. More fuel in takes away none of the petrol — it only makes you with more of the same blend. - Being seen comes before the rest beside moving traffic: switch the hazard lights on, and only then think about everything else. - However short the distance, starting it to move it is the thing to avoid. At a forecourt, push the vehicle clear of the petrol pump by hand instead, then ask the staff to lend a hand. - The first thing we will ask is which fuel you put in and about how much — and the till receipt shows both. Keep it. On the M1, under 10 miles from Hallam Head, the next exit is the location to leave the vehicle; elsewhere, the first safe place to stop. Don't press on to the services. Then go back to stage one. ## The fork in each Hallam Head fuel drain: has it run yet? What comes next turns on one answer, and just one. Engine not run at all? - The petrol sits inside that tank, and just there. - The work is a drain and a flush, usually done where the car is. - Step one counts for exactly this reason: it is the best spot to be in. Run at all, even for a second: - The fuel lines and your filter now hold petrol pulled out of that tank. - A bigger run takes it right through to the high-pressure fuel pump and the injectors. - Lines flushed, the filter dealt with, and sometimes more: this job grows as the miles does. That line falls there because diesel protects the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left still, damages nothing. Pump the petrol, though, and it wears the very parts doing the moving. ## Hallam Head, petrol in a diesel: have these ready before you call Get ready a little, and the technician finds you rather than circling. - Where you have stopped. A postcode starting S10 5 is the ideal place to start. - A road name is a help: Pitchford Lane, say, or whichever street you've stopped in. A car park works too. - Describe a car park by what it serves — the one outside Co-op Food, for instance — and it's much quicker to find. - That it is a diesel, along with the make and model of your vehicle. - Which got in matters: AdBlue is a separate job from petrol, plus Hallam Head has a page for it. So say. - About how much — in litres from your receipt, or by how long the nozzle stayed in. - Whether it's run. And if it has, how far plus how heavily. - The owner may have to authorise this work under some hire and company agreements — which is why it's quicker to settle whose car it is before we get there. Phone 0333 366 0103 then. Writing to works as well if it can wait, with the car left at home, going nowhere. ## Hallam Head fuel drain on its way? Whilst you wait In the wait, the damage comes from well-intended help — which is why these count. - Wait with your car 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. - Nobody — however kind — starts it, whether to see if it runs or to move the vehicle a short way. - Additives stay in your boot. Injector cleaner and two-stroke oil take none of that petrol out once more. - A home-made drain leaves your fuel already gone beyond your tank, and siphoning petrol by the road is dangerous too. - Ignition stays off. Even for your radio or the windows. ## Van arrived? The fuel drain, one step at a time - Our quote comes after three queries, not before them — what was put in, how much, and whether it has run — because those replies shape this job. - That tank is drained. The polluted mixture comes from your tank. - The lines are flushed. If it ran, that petrol has shifted beyond the tank, and the lines are carrying it. - Then the filter: replaced where there's a workable one, cleared where there's not. - Priming follows once clean diesel is in. - Our technicians start the car only after clean diesel has gone in and primed the fuel system, then make sure that it's running properly. The car has fresh diesel running through it before we leave. Lasting damage is very rare if it has been spotted early, so the car can go straight back to normal use. ## After your fuel drain is done: driving around Hallam Head a second time - Nothing special is needed after a start with clean diesel — ordinary driving will do. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and call us once more. - Keep the documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Hallam Head itself Hallam Head is a suburban area located on the outskirts of Sheffield, situated near the River Don in South Yorkshire.
