Engine off. Keep the car like that — no moment on, no moving it at all. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and nothing decides that more than the next few minutes do. From now on, step by step, for anywhere in Beecroft: ## Petrol in a diesel, engine off — the first minute First, these — in this sequence. - Bleeding your fuel system pulls petrol from the tank toward the parts it damages, and switching the ignition on can be all it takes to do that. So the keys come out, and the ignition remains off altogether. - Don't top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mix. - Near moving traffic? Then your hazards go on before anything else, and so the car is simple to see. - However short the way, starting it to move it is the mistake. At a forecourt, push the car clear of the pump by hand instead, then ask the staff to lend a hand. - Hold on to the till receipt. It says which fuel got in and roughly how much, which is the first thing we'll ask. On the M1, under 3 miles from Beecroft, the next junction is the spot to leave the vehicle; elsewhere, the first safe location to stop. Don't press on to the services. Then go back to stage one. ## Has it run yet? The fork in each Beecroft fuel drain Everything after this point depends on one answer. Motor never run at all? - Just that tank has petrol in it so far. - A drain and flush, on the spot, is normally the whole job. - No position is better, and it is why the first step matters so much. If it has been started, even for a second: - Petrol has been drawn from the tank, through your filter and into your lines. - A longer run takes it right through to the high-pressure fuel pump and the injectors. - The further it went, the bigger the job — your lines, the fuel filter, and sometimes more besides. Diesel keeps the high-pressure fuel pump and the injectors lubricated as it runs through them. Petrol offers them nothing, and that is why the line is drawn there. Nothing is harmed by petrol that is only sitting in a tank. As soon as it's pumped, petrol begins wearing whatever moves it. ## Calling about petrol in a diesel from Beecroft: what to have prepared Prepare a little, and the technician finds you instead of circling. - LU6 1 plus the rest of the postcode is the best way to start telling us where you are. - A road name is a help: Drovers Way, say, or whatever street you have stopped in. A car park works too. - What a car park serves is the quickest way to find it, and so say the landmark — such as the one at Co-op Food. - Tell us what the car is — make, model — and confirm it's diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Beecroft page. - How long the nozzle was in, or the litres on your receipt — whichever gives us how much. - Has it run? If so, say how far it went, and how it was driven. - The owner may have to authorise the work under some hire or company contracts — so it is faster to settle whose car it is before our technicians arrive. Call 0333 366 0103 next. Writing to is fine as well if it can wait, with the vehicle left at home, going nowhere. ## While you wait for a fuel drain around Beecroft Help, however well meant, is what does the harm whilst you wait. So stick to these. - Safety before the vehicle. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it is, stay with it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - A DIY drain leaves your fuel already gone beyond the tank, and siphoning petrol by the road is risky too. - Not for your radio, not for the windows: the ignition remains off. ## Van arrived? The fuel drain, one stage at a time - The quote comes after three questions, not before them — what went in, how much, and whether it's run — since the answers set the job. - Your tank is emptied. The polluted mix comes from your tank. - If it ran, your lines are holding petrol that has shifted beyond the tank — so they are cleaned. - Your filter is dealt with. Cleared, or swapped where the vehicle has a usable one. - The system is primed with fresh diesel. - We start it only after new diesel has gone in and bled your system, then check that it's running correctly. Only once it's running on new diesel do our technicians leave. It's very unusual for a vehicle noticed soon to be left with permanent damage, and normal use resumes straight away. ## Once your fuel drain is done: driving in Beecroft once more - After it has been started on fresh fuel, there's nothing special to do: drive normally. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and call us back. - Your paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, go by the petrol pump's label instead of the colour of its handle. ## About Beecroft itself Beecroft is a suburban area in Bedfordshire, situated approximately 31.6 miles north of London and 12.6 miles northwest of St Albans.
