Here Is What Happens Whatever you do, don't switch the motor on, even for a moment, to move it. Pause; leave the vehicle off. The coming few minutes decide it far more than anything else: petrol in a diesel still unrun usually amounts to draining and flushing, on the spot. From now on, step by step, wherever you are in Wheatley: ## Minute one: petrol in a diesel, engine off Work through these in order, before you do anything else. - Keys out of the ignition. Switching the ignition on can be all it takes to prime your fuel system, and priming pulls petrol out of your tank toward the components it damages. Keep it off completely. - Topping up with diesel seems like it thins the trouble. It does not: nothing gets out, and your tank simply carries more of the same. - Being seen comes first beside moving traffic: switch your hazards on, and only then deal with anything else. - By hand, never on the engine: that's how it leaves the pump. Get the forecourt attendants to help you push, whatever the mileage. - Which fuel, and about how much? Your receipt answers both, and that is where our first question starts. Don't throw it away. On the A1(M), under 3 miles from Wheatley, the next junction is the spot to leave the vehicle; elsewhere, the first safe spot to stop. Do not press on to the services. Then go back to step one. ## Has it run yet? The fork in every Wheatley fuel drain What comes after this turns on one answer, and only one. If your motor has not run at all: - That petrol is still in that tank and nowhere else. - The work is a drain and a flush, normally done where the vehicle is. - This is as good as it gets — which is the whole point of stage one. If your engine has run, even briefly: - From your tank, past the fuel filter, into your lines: that's how far that petrol has got. - The high-pressure pump as well as your injectors see it too on a bigger run. - The further it went, the bigger this job — your lines, the fuel filter, and sometimes more besides. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. In your tank, left alone, petrol does no harm. The components that shift it are grinding the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Wheatley Whether the van circles or finds you depends on a little preparation. - The best start is a postcode — one beginning DN2 4 — for where you are. - A road name is a help: Axholme Road, say, or whatever street you have stopped in. A car park does the trick too. - What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Aldi. - Tell us what your car is — make, model — and confirm it's diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Wheatley page. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - Has it run? If so, say how far it got, and how it was driven. - Settle who owns the vehicle before we arrive: some hire and company agreements want the owner to approve the work, and doing it faster first. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## The wait for a Wheatley fuel drain, and what to do in it The wait is where well-meant help does the damage. Hold to these. - Where your car has stopped settles where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards. - Something from the boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol. - A home-made drain misses the fuel already gone beyond the tank, and siphoning petrol by the road is hazardous too. - Even the radio or your windows aren't worth switching the ignition on for. ## When our van arrives: your fuel drain, step by step - Three questions. What was put in, how much, and whether it's run. The replies decide this job, which is why our price comes after them and not before. - Out of the tank comes the tainted mix: your tank is emptied. - Your lines are rinsed. If it ran, the petrol has shifted beyond your tank, and the lines are holding it. - Then the fuel filter: changed where there's a usable one, cleared where there's not. - Fresh diesel goes in, then the fuel system is primed. - The first start on fresh diesel. Once priming is done, the motor is started and we confirm that it runs properly. The vehicle has new diesel running through it before our technicians leave. Permanent damage is very uncommon when it has been noticed soon, so the car can go straight back to normal use. ## After your fuel drain is done: driving in Wheatley a second time - Started on clean diesel, it needs nothing unusual of you. Just drive normally. - Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from the exhaust, an idle that is lumpy, 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 Wheatley and where it is Wheatley is a suburban area situated on the riverside in South Yorkshire, with an elevation of 19 metres above sea level.
