Here Is What Happens Whatever you do, never switch the motor on, even for a moment, to move it. Stop; leave the car off. Hasn't been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the car has stopped — and nothing decides that as much as these next few minutes do. Below is the sequence from this point, anywhere around Hillside you are. ## Petrol in a diesel? What to do in minute one Do these first, in this sequence. - Pull the keys out. Even your ignition on its own can prime the system, pulling petrol out of your tank to precisely the parts it damages, and so keep the vehicle off wholly. - Topping up with diesel seems like it dilutes the issue. It doesn't: nothing gets out, and that tank simply carries more of the same. - Close to passing traffic? Then the hazard lights go on before anything else, and so your car is easy to see. - However short the way, starting it to shift it is the thing to avoid. At a forecourt, push the car away from the petrol pump by hand instead, then ask the attendants to help. - The first thing you will be asked is which fuel you put in and about how much — and the receipt says both. Hold on to it. On the M32, under 15 miles from Hillside, the next exit is the location to come off; elsewhere, the first safe location to stop. Don't press on to the services. Then go back to stage one. ## Has it run yet? The fork in every Hillside fuel drain What happens after this turns on one answer, and only one. If it has never been started: - Nowhere but the tank: that is where that petrol yet is. - The job is a drain and a flush, usually done where your car stands. - This is the best position to be in, and the whole reason step one matters. Motor run, even for a moment? - From your tank, through the fuel filter, into the fuel lines: that is how far the petrol has got. - On a longer run it has got to the high-pressure pump as well as the injectors. - The job expands with the mileage — lines flushed, filter seen to, occasionally more. That line falls there since diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol does not. Nothing is harmed by petrol that's only waiting in a tank. Petrol being pumped is grinding down the parts that move it. ## Calling about petrol in a diesel from Hillside: what to have prepared A little planning is the difference between a van that finds you and a technician that circles. - BA3 2 plus the rest of the postcode makes the ideal way to start telling us where you are. - A road name helps: Withies Park, say, or whichever street you've stopped in. A car park works too. - Name a car park by what it serves — the one outside Sainsbury's, for example — and it is far quicker to find. - Tell us what your vehicle is — make, model — and check it's diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Hillside page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The miles it covered, and how heavily, if it ran at all. - Whose motor it is. Some hire or company agreements want the owner to authorise the work, and that's quicker settled before we arrive than after. Phone 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Hillside: what to do The wait is where well-intended help does the harm. Stick to these. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of that petrol out a second time. - No home-made emptying. Siphoning petrol into a can at the roadside is dangerous, and it leaves your fuel that has already gone beyond your tank. - Not for your radio, not for the windows: the ignition remains off. ## The fuel drain, step by step, after our van gets there - Our quote comes after three questions, not before them — what was put in, how much, and if it has run — since those answers set the job. - Out of the tank comes the polluted mixture: that tank is emptied. - Your lines are flushed. If it ran, that petrol has shifted beyond your tank, and your lines are holding it. - Cleared, or changed if the car has a serviceable one: the filter is seen to next. - Fresh diesel goes in, and the fuel system is primed. - We start it only after clean diesel has gone in and bled the fuel system, then make sure that it is running smoothly. The car has clean diesel running through it before our technicians leave. The vehicle goes back to normal use straight away, and lasting damage is very unusual if it has been caught soon. ## Once the fuel drain is done: driving around Hillside once more - After it has been started on fresh fuel, there is nothing special to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us a second time. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to the paperwork. - Next time, read the pump. The label, not the colour of the handle. ## About Hillside and where it is Hillside is a suburban area situated on the riverside in Somerset, with an elevation of 106 metres.
