Pause; leave the car off. The coming few minutes decide it more than anything else: petrol in a diesel still unrun generally comes down to clearing then flushing, right there. From now on, in order, for anywhere in Hampstead Norreys: ## Petrol in a diesel? What to do in minute one In this order, and before anything else: - Take the keys out. Even your ignition on its own can prime the fuel system, pulling petrol out of your tank to exactly the parts it damages, so keep the car off wholly. - No diesel on top. More fuel in takes away none of that petrol — it only makes you with extra of the same mixture. - Being seen comes before the rest beside moving traffic: put your hazards on, and only then think about everything else. - By hand, never on your engine: that's how it comes off the petrol pump. Ask the forecourt attendants to help you roll, however short the distance. - Hold on to your receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask. Still on the move when you noticed? Come off the M4 at the next exit if that's where you are, under 3 miles from Hampstead Norreys, and stop somewhere safe instead of pushing on to the services. Then begin at step one. ## The fork in every Hampstead Norreys fuel drain: has it run yet? What happens next turns on one answer, and only one. If it has not once been started: - Just the tank has petrol in it so far. - Usually it's emptied and cleaned just where the car is. - No spot is better, and it is why the first stage matters so much. Run at all, however briefly: - The fuel lines and the filter now hold petrol drawn from your tank. - Your high-pressure pump as well as the injectors get it on a bigger run. - Miles is what turns it into a larger job: the lines flushed, a filter seen to, and at times more than that. Petrol doesn't lubricate. Diesel does, protecting your pump and injectors as it passes through, which is why the line falls where it does. Nothing is harmed by petrol that is only waiting in a tank. Petrol being pumped is wearing the parts that move it. ## What to have prepared when you call about petrol in a diesel from Hampstead Norreys Prepare a little, and the technician finds you rather than circling. - Your whereabouts: a postcode beginning RG18 0 serves best. - The street or the car park. A road name helps — Pendalls Close, or wherever you have pulled up. - Or the nearest landmark. A car park is easier to find by what it serves, such as the one outside Co-op Food. - Make and model of your car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Hampstead Norreys page. - How much. Litres from your receipt, or how long the nozzle was in. - Whether it has run. And if it has, how far plus how hard. - Whose vehicle it is. Some hire and company contracts want the owner to authorise the work, and that is quicker settled before we turn up than after. Phone 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Hampstead Norreys: what to do Help, however well meant, is the thing that does the damage whilst you wait. So hold to these. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it stands, wait with it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a few yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets that petrol back out. - Siphoning petrol into a can by the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Do not drain it yourself. - Even the radio or the windows aren't worth switching your ignition on for. ## Step by step: your fuel drain when the van arrives - First, three questions: which fuel went in, the volume, and has it run? Those replies decide the job, so our quote follows them. - Then the tank is drained, so the contaminated fuel is taken out. - The lines are flushed. If it ran, that petrol has shifted beyond that tank, and the fuel lines are holding it. - Then your filter: changed where there's a serviceable one, cleared where there is not. - The fuel system is primed on fresh diesel. - The start. With clean diesel in and your system primed, it's fired up and tested to confirm it runs smoothly. Only once it's running on fresh diesel do we leave. Long-term damage is very unusual if it has been noticed quickly, so the car can go right back to normal use. ## After the fuel drain is done: driving in Hampstead Norreys once more - Drive normally. There's nothing unusual to do once it's been started on clean fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over then ring us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so keep your documents. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Hampstead Norreys, briefly Hampstead Norreys is a village in Berkshire, situated on the banks of a river at an elevation of around 88 metres.
