Engine off. Leave it that way — no second on, no shifting it anywhere. Cleared then purged, just where it is: that is usually all an unrun diesel with petrol in it takes. Whether it stays that straightforward depends on the minutes ahead far more than on everything else. What follows is the sequence from this point, wherever in Mushroom Green you happen to be. ## Petrol in a diesel? What to do in minute one Go through the following in sequence, before you do anything else. - Pull the keys out. Even the ignition by itself can prime the system, pulling petrol out of your tank to exactly the components it damages, and so leave it alone completely. - Topping up with diesel seems like it dilutes the problem. It does not: nothing comes out, and that tank just holds more of the same. - Hazard lights on. If you're at all close to moving traffic, make your car simple to see before you do anything else. - The staff will normally help you push it away from the petrol pump. Ask, then move it by hand — not on your engine, even for a couple of yards. - Keep the till receipt: the grade and roughly how much are written on it, and they're what our engineers ask for first. On the M5, under 3 miles from Mushroom Green, the next exit is the place to leave the car; anywhere, the first safe place to stop. Do not push on to the services. Then go back to stage one. ## Every Mushroom Green fuel drain starts here: has your engine run? What happens after this rests on one answer, and just one. If the motor hasn't run at all: - Just your tank has petrol in it for now. - A drain and flush, on the spot, is usually the whole job. - No place is better, and it's why the first stage counts so much. If it has been started, even for a second: - From your tank, past the filter, into your lines: that's how far that petrol has got. - The high-pressure fuel pump as well as the injectors get it on a bigger run. - Flushing your lines, the filter sorted, occasionally more: the job grows as the distance does. That line falls there because diesel protects your high-pressure pump and your injectors on its way through them — and petrol doesn't. Petrol sitting in a tank harms nothing. The parts that shift it are grinding the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Mushroom Green Get ready a little, and the technician finds you rather than circling. - The ideal start is a postcode — one starting DY2 0 — for where you are. - The road or the car park. A road name helps — Quarry Road, or wherever you have stopped. - Name a car park by what it serves — the one at Hawthorne & Walker Fine Food Ltd, for instance — and it is far easier to find. - The make and model of your vehicle, and the fact it's a diesel. - Which got in counts: AdBlue is a separate job from petrol, and Mushroom Green has a page just for that. So say. - How much. Litres from the receipt, or how long the nozzle was in the filler. - Has it run? If so, tell us how far it went, and the way it was driven. - Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that's easier settled before our engineers get there than after. Then call 0333 366 0103. If it can wait — the car is at home and going nowhere — works too. ## Mushroom Green fuel drain on its way? Whilst you wait The wait is where kindly meant help does the damage. Hold to these. - Your safety comes before your car. Somewhere exposed? Get clear of the traffic and wait away from it. Fine where it is? Wait with it. - A helpful passer-by doesn't crank it. Nor does anybody checking it still does the trick, or rolling it a few yards. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of that petrol out a second time. - Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank remains where it is anyway. - Leave the ignition off — the windows and the radio included. ## When the van gets there: your fuel drain, step by step - Fuel, volume, whether it has run: the answers decide this job, and that's why you get a price after them instead of before. - Out of the tank comes the polluted mixture: your tank is emptied. - Petrol that has shifted beyond the tank travels in the fuel lines once it ran, and your lines are flushed to clear it. - Where the car has a usable filter, it is swapped; otherwise, cleared. - Clean diesel in, and your system primed. - The start. With new diesel in and the system bled, it is started and checked to be sure it runs smoothly. Your car has fresh diesel running through it before our technicians head off. It is very rare for a vehicle caught early to be left with long-term damage, and normal use starts again right away. ## After your fuel drain: back on the road in Mushroom Green - Drive normally. There is nothing unusual to do after it has been started on fresh fuel. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us once more. - The paperwork 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 pump is. ## About Mushroom Green itself Mushroom Green is a suburban area situated lakeside in the West Midlands, with an elevation of 103 metres.
