Here Is What Happens Whatever you do, don't switch your motor on, even briefly, to move the car. Pause; leave the vehicle off. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the car has stopped — and nothing settles that more than these next few minutes do. What follows is the order from this point, anywhere around Church End you are. ## Petrol in a diesel? What to do in minute one Work through these before anything else, in this order. - Priming the system pulls petrol from the tank toward the components it damages, and switching the ignition on can be all it takes to do that. So the keys get taken out, and your ignition remains off altogether. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Being seen comes first near moving traffic: put your hazards on, and only then think about anything else. - The staff will generally help you push it clear of the petrol pump. Let them, then move it by hand — never on the engine, even for a couple of yards. - Which fuel, and about how much? Your receipt replies that, and that's where our first question starts. Do not throw it away. Still driving when you noticed? Come off the M40 at the next junction if that's where you are, under 10 miles from Church End, and stop somewhere safe instead of pushing on to the services. Then start at step one. ## The fork in each Church End fuel drain: has it run yet? Everything after this stage depends on one answer. Not run, not even once: - No place but that tank: that is where the petrol yet is. - Where the car stands is normally where the work happens: a drain, then a flush. - This is the best spot to be in, and the reason step one counts. If your engine has been run, even briefly: - Out of that tank, past your filter, into the fuel lines: that's how far that petrol has got. - Run it farther and that petrol gets to the injectors, having passed through your fuel pump first. - Mileage is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work. Why the line falls there: diesel protects the high-pressure pump as well as the fuel injectors as it passes through them, and petrol does not. In the tank, left alone, petrol harms nothing. Petrol being pumped is wearing the components that move it. ## Calling about petrol in a diesel from Church End: what to have prepared Get ready a little, and the technician finds you instead of circling. - The ideal start is a postcode — one starting NN11 6 — for where you are. - Wherever you have parked, the road's name helps — whether that's Becketts Close or somewhere else — and so does the name of a car park. - Or the landmark. A car park is easier to find by what it serves, such as the one outside Co-op Food. - Tell us what your car is — make, model — and check it is diesel. - Say which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Church End. - How much. Litres from your receipt, or how long the nozzle was in. - The miles it did, and how heavily, if it has run at all. - Hire or company car? Some contracts want the owner's go-ahead for this work, and getting it before we get there is quicker than after. Ring 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use . ## While you wait for a fuel drain around Church End Stick to these: well-meant help does the damage during the wait. - Safety before your car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it. - A helpful passer-by does not start it. Nor does anyone wanting to check it still does the trick, or moving it a couple of yards. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of that petrol out once more. - No DIY draining. Siphoning petrol into a can at the kerbside is hazardous, and it leaves the fuel that has by now gone beyond your tank. - Leave your ignition off — the windows and your radio too. ## The fuel drain, step by step, after our van arrives - Three questions. What went in, how much, and if it has run. Those answers decide this job, which is why our price comes after them and not before. - Draining it is how the mixture gets taken out of that tank. - Flushing the lines follows, because a motor that ran has petrol past that tank, in your lines themselves. - Where your car has a serviceable filter, it's swapped; if not, cleared. - Clean diesel goes in, then the fuel system is primed. - The first start on clean diesel. When priming is complete, the engine is fired up and our technicians check that it runs properly. The car has clean diesel running through it before we leave. If it has been noticed quickly, long-term damage is very unusual, and the vehicle goes back to normal driving straight away. ## Once the fuel drain is done: driving in Church End again - Started on clean diesel, it asks nothing unusual of you. Simply drive normally. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over and ring us back. - The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, trust the petrol pump's label rather than the colour of its handle. ## About Church End itself Church End is a suburban area in Northamptonshire, situated inland at an elevation of around 150 metres.
