Cleared and purged, just where it sits: that's normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes to come more than on everything else. Here's the order of things from here, anywhere you are around Dunchurch. ## Petrol in a diesel? What to do in minute one Do these first, in this order. - Take your keys out. Even the ignition on its own can prime your fuel system, drawing petrol out of your tank to precisely the components it harms, so keep the car alone entirely. - A bigger tank of the same mix is all topping up gives you, because it takes out nothing. So no extra diesel. - Hazard lights on. If you're anywhere near moving traffic, make your car easy to see before you do anything else. - Off the pump by hand. At a forecourt, get the attendants to help you roll the car clear of the petrol pump. Don't crank it to shift it, however short the way. - Hold on to the till receipt. It shows which fuel went in plus about how much, which is the first thing we will ask. Still on the move when you noticed? Come off the M45 at the next junction if that is where you are, under a mile from Dunchurch, and stop somewhere sensible instead of pressing on to the services. Then start at step one. ## The fork in every Dunchurch fuel drain: has it run yet? From this point on, everything hinges on a single answer. If your engine hasn't run at all: - The petrol remains inside your tank, and just there. - Normally it is drained and purged just where the vehicle stands. - No spot is better, and it is why the first stage counts so much. Engine run, however briefly? - Petrol has been drawn out of that tank, past the filter then into the fuel lines. - Run it further and that petrol gets to the injectors, having gone through the pump first. - The farther it went, the bigger the job — your lines, your filter, and now and then more besides. Diesel keeps the high-pressure pump and the injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Nothing is harmed by petrol that's just waiting in a tank. As soon as it is pumped, petrol begins grinding whatever moves it. ## Calling about petrol in a diesel from Dunchurch: what to have ready Prepare a little, and the van finds you rather than circling. - CV22 6 and the rest of the postcode makes the best way to begin telling us where you are. - Name the road — Southam Road or wherever you have stopped — or the car park. - Describe a car park by what it serves — the one at Sainsbury's, for instance — and it is far quicker to find. - Make and model of the car, and the fact it is a diesel. - Tell us which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Dunchurch. - How long the nozzle was in, or the litres on the receipt — either gives us how much. - Whether it has run. And if it has, how far and how hard. - Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before we get there is quicker than afterwards. Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere — does the trick too. ## Dunchurch fuel drain on its way? Whilst you wait During the wait, the harm comes from kindly meant help — so these matter. - Safety before your car. If it has stopped somewhere exposed, get yourself away from the traffic and wait away from it. If it's safe where it sits, wait with it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - No home-made emptying. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has by now gone beyond your tank. - Not for your radio, not for your windows: the ignition remains off. ## Step by step: your fuel drain when our van arrives - Our quote comes after three questions, not before them — what went in, how much, and whether it's run — because those answers shape the job. - Clearing it's how the blend gets taken from the tank. - The lines are flushed. If it ran, that petrol has moved beyond the tank, and the lines are carrying it. - Where the vehicle has a usable filter, it's swapped; otherwise, cleared. - Priming comes after clean diesel is in. - We start the engine only after new diesel has gone in and bled your system, then check that it's running properly. Our technicians wait until it's running on new diesel. The car returns to normal use straight away, and permanent damage is very rare if it has been noticed early. ## After your fuel drain: back on the road in Dunchurch - Drive normally. There is nothing unusual to do after it has been started on clean fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then call us back. - The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour is not the thing to go by next time — the label on the petrol pump is. ## About Dunchurch and where it is Dunchurch is a village in Warwickshire, situated inland at an elevation of 124 metres, approximately 10 miles south of Coventry.
