Here Is What Happens Stop. Motor off. Keep the vehicle like that — no moment on, no moving it at all. Cleared and purged, right where it is: that's usually all an unrun diesel with petrol in it needs. Whether it stays that simple rests on the minutes ahead more than on everything else. Wherever you are around Barton, this is how things run from here. ## Engine off: minute one with petrol in a diesel Work through the following in sequence, before you do anything else. - Keys out of your ignition. Switching the ignition on can be all it takes to prime your fuel system, while priming pulls petrol out of the tank toward the parts it damages. Keep it off altogether. - Topping up with diesel sounds like it thins the problem. It doesn't: nothing gets out, and the tank simply holds more of the same. - Make the vehicle simple to see first — hazard lights on — if there is moving traffic anywhere near you. - Off the pump by hand. At a forecourt, ask the attendants to help you push it away from the petrol pump. Do not crank it to shift it, however short the way. - Hold on to the receipt. It says which fuel went in plus about how much, which is the first thing we'll ask. On the M40, under 5 miles from Barton, the next exit is the location to come off; anywhere, the first sensible spot to stop. Don't push on to the services. Then go back to step one. ## Every Barton fuel drain starts here: has your motor run? One answer is what everything after this point rests on. If the engine hasn't run at all: - All the petrol remains inside the tank, and only there. - Usually it is drained and rinsed right where the vehicle stands. - No place is better, and it is why the first stage matters so much. If it's been started, even for a second: - Some petrol has left that tank already, gone through the fuel filter, and got into the lines. - On a longer run it has got to the high-pressure fuel pump and your injectors. - Distance is what turns it into a bigger job: the lines flushed, a filter seen to, and at times further work. Why the line falls there: diesel protects the high-pressure fuel pump and your injectors as it passes through them, and petrol doesn't. A tank of petrol, left still, damages nothing. Petrol being pumped is wearing the parts that move the vehicle. ## What to have prepared when you call about petrol in a diesel from Barton A van that circles versus a technician that finds you: a little preparation is what separates them. - Your location: a postcode starting OX3 9 works best. - A road name is a help: Waynflete Road, say, or whichever street you have stopped in. A car park works too. - What a car park serves is the quickest way to find it, and so mention the landmark — such as the one outside Waitrose. - The vehicle. Make, model, and that it's a diesel. - Which got in counts: AdBlue is a separate job from petrol, plus Barton has a page just for that. So say. - How much. Litres from the receipt, or how long the nozzle was in the filler. - Whether it's run. Then if it has, how far plus how heavily. - The owner may have to authorise this work under some hire and company contracts — so it's quicker to settle whose vehicle it is before we get there. Then call 0333 366 0103. If it can wait — the car is at home and going nowhere — works as well. ## The wait for a Barton fuel drain, and what to do in it Stick to these: kindly meant help does the harm during the wait. - Your safety comes before the vehicle. Somewhere unsafe? Get clear of the traffic and wait away from it. Fine where it stands? Stay with it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a few yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that gets that petrol back out. - A home-made drain leaves the fuel that has already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Even your radio or the windows aren't worth switching the ignition on for. ## Step by step: the fuel drain when the van arrives - Three queries. What went in, how much, and whether it has run. Those answers decide the job, which is why the price comes after them but not before. - Then your tank is emptied, so the polluted fuel comes out. - Petrol that has moved beyond that tank travels in the lines once it ran, and the lines are flushed to clear it. - Then the fuel filter: changed where there is a workable one, cleared where there's not. - Clean diesel goes in, then the system is primed. - Our engineers fire it up only after new diesel has gone in and primed the fuel system, then confirm that it's running smoothly. Only once it's running on new diesel do our engineers leave. When it has been noticed early, lasting damage is very rare, and the car returns to normal use straight away. ## After the fuel drain: back on the road around Barton - Once it has been started on fresh fuel, there's nothing special to do: drive normally. - Pull over and call us back if anything looks wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot. - An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the documents. - Read the label on the petrol pump next time, not the colour of the handle. ## About Barton itself Barton is a suburban area located on the riverside in Oxfordshire, sitting at an elevation of 101 metres.
