Here Is What Happens Stop. Engine off. Keep it that way — no moment on, no shifting it anywhere. Petrol in a diesel that has not been run is generally a drain and a flush, done right where your car sits, and what you do in the next few minutes determines that more than anything else. Anywhere you happen to be in Wooburn Green, this is the order things run from here. ## Petrol in a diesel, motor off — the first minute Do these before anything else, in this order. - Priming the system draws petrol from your tank toward the components it damages, and turning the ignition on can be enough to do that. So the keys come out, and the ignition stays off completely. - No diesel on top. More fuel in removes none of the petrol — it just makes you with more of the same blend. - Hazards on. If you are at all near moving traffic, make the car easy to see before you do anything else. - However short the way, starting it to move it is the mistake. At a forecourt, push the vehicle away from the petrol pump by hand instead, then ask the staff to help. - Keep the receipt. It shows which fuel got in plus about how much, which is the first thing we will ask. If you were still driving when you realised, pull over somewhere safe instead of pushing on for the services — on the M40, under a mile from Wooburn Green, that means the next junction. Step one follows. ## Each Wooburn Green fuel drain starts here: has your motor run? From this point on, everything hinges on a single answer. If the engine has not run at all: - The petrol remains in that tank, and just there. - Normally it is emptied and flushed right where the vehicle stands. - Step one counts for precisely this reason: it's the best spot to be in. Run at all, however briefly: - Petrol has been pulled out of the tank, past the filter and into the fuel lines. - A bigger run carries it right through to your high-pressure pump and your injectors. - The farther it went, the bigger the job — the lines, the fuel filter, and now and then more besides. The reason the line falls there: diesel protects the high-pressure fuel pump and the fuel injectors as it passes through them, and petrol doesn't. Nothing is harmed by petrol that's just sitting in a tank. Petrol being pumped is wearing the components that shift it. ## Before you call about petrol in a diesel around Wooburn Green: what we need A van that circles against a technician that finds you: a little planning is the difference. - The ideal place to start is a postcode — one beginning HP10 0 — for where you are. - The street or the car park. A road name is a help — Waterside, or wherever you have stopped. - What a car park serves is the easiest way to find it, and so say the landmark — like the one at Tesco. - Say what the vehicle is — make, model — and check it's diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Wooburn Green page. - The quantity: the receipt's litres, or else how long you held the nozzle in. - The mileage it did, and how hard, if it has run at all. - The owner may have to authorise this work under some hire or company contracts — so it is faster to settle whose vehicle it is before our technicians arrive. Phone 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use . ## Wooburn Green fuel drain on its way? While you wait Stick to these: well-meant help causes the damage during the wait. - Safety before the car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it sits, stay with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: nobody starts it. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - Siphoning petrol into a can at the roadside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain. - Not for your radio, not for the windows: your ignition remains off. ## When the van gets there: the fuel drain, step by step - Our price comes after three queries, not before them — what went in, how much, and if it's run — because the replies shape this job. - The tank is cleared. The contaminated blend comes out of the tank. - Purging the lines comes next, since a car that ran has petrol past your tank, inside your lines themselves. - Your filter is sorted. Cleared, or replaced where the car has a usable one. - Clean diesel in, and your system primed. - Our technicians start it only after clean diesel has gone in and bled your system, then confirm that it is running smoothly. Your car has fresh diesel running through it before our technicians go. The car goes back to normal driving at once, and lasting damage is very rare if it has been caught soon. ## After your fuel drain is done: driving around Wooburn Green again - Drive normally. There is nothing unusual to do once it's been started on fresh fuel. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over then call us back. - An insurer, a fleet manager or a hire firm may ask what was done, and so hold on to your paperwork. - Next time, trust the pump's label rather than the colour of its handle. ## About Wooburn Green itself Wooburn Green is a village situated on the River Thames in Buckinghamshire, with a mix of semi-detached housing and a population of around 1778 residents.
