Here Is What Happens Pause, then keep the motor off — not on, and not for a moment to move the vehicle. Emptied then rinsed, right where it is: that is normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead more than on anything else. From here on, step by step, for anywhere in Greytree: ## Minute one: petrol in a diesel, motor off First, the following — following this sequence. - Ignition off, keys out. Switched on, the ignition can prime your system — and priming is what moves petrol out of your tank towards the components it harms. - No diesel on top. More fuel in takes away none of that petrol — it just makes you with more of the same mixture. - Near moving traffic? Then the hazards go on before everything else, so the car is simple to spot. - However short the distance, starting it to shift it is the mistake. On a forecourt, roll the vehicle away from the pump by hand instead, then ask the attendants to help. - Which fuel, and roughly how much? Your receipt answers both, and that is where our first question starts. Never throw it away. Still driving when you noticed? Come off the M50 at the next junction if that's where you are, under 3 miles from Greytree, and stop somewhere sensible rather than pushing on to the services. Then begin at step one. ## The fork in each Greytree fuel drain: has it run yet? From this stage on, everything hinges on a single answer. Engine never run at all? - That petrol is still inside the tank and nowhere else. - Usually it is drained and purged just where the car stands. - Stage one matters for precisely this reason: it is the best spot to be in. If it has been started, even for a second: - Some petrol has left that tank already, passed through the fuel filter, and got into your lines. - The high-pressure fuel pump and the fuel injectors get it on a longer run. - The job grows with the mileage — lines purged, filter seen to, sometimes more. That line falls there since diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol doesn't. Petrol resting in a tank harms nothing. The parts that shift it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Greytree: what to have ready A little preparation is the difference between a technician that finds you and a technician that circles. - HR9 7 plus the remainder of the postcode makes the ideal way to start telling us where you are. - Wherever you have parked, the road's name helps — whether that is Fourth Avenue or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, and so say the landmark — like the one outside Co-op Food. - That it's a diesel, along with the make and model of your car. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Greytree page. - How much. Litres from your receipt, or how long the nozzle was in the filler. - The distance it did, and how hard, if it has run at all. - Settle who owns the car before we arrive: some hire or company contracts want the owner to approve this work, and that is faster first. Next, 0333 366 0103. Not pressing, the vehicle parked at home with nowhere to be? Then will do as well. ## Greytree fuel drain on its way? While you wait In the wait, the damage comes from well-meant help — which is why these matter. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself clear of the traffic then wait away from it. If it's safe where it sits, wait with it. - No one — however helpful — starts it, whether to see if it runs or to move the vehicle a short way. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - A DIY drain leaves your fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Not for the radio, not for the windows: your ignition remains off. ## Van arrived? Your fuel drain, one stage at a time - Fuel, quantity, whether it's run: those replies set the job, and that's why you get a price after them instead of before. - That tank is cleared. The polluted blend comes out of your tank. - Petrol that has shifted beyond your tank travels in the fuel lines if it ran, and the fuel lines are rinsed to clear it. - The filter is seen to. Cleared, or replaced where the car has a serviceable one. - Your system is primed with clean diesel. - First start on clean diesel. When bleeding is finished, your engine is started and our technicians confirm that it runs smoothly. The car has new diesel running through it before our technicians head off. Long-term damage is very unusual when it has been noticed soon, so the vehicle can go right back to normal driving. ## After your fuel drain: back on the road around Greytree - Nothing unusual is needed after a start with clean diesel — ordinary driving is all. - Pull over and ring us back if anything seems wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - The documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour isn't the guide to go by next time — the label on the pump is. ## About Greytree itself Greytree is a locality in Herefordshire, situated on the riverside at an elevation of 37 metres, with detached housing being the predominant type of accommodation.
