Engine off. Keep the car like that — no second on, no shifting it anywhere. The coming few minutes decide it far more than anything else: petrol in a diesel still unrun generally amounts to clearing then rinsing, right there. From now on, in order, wherever you are around Mossley Brow: ## Petrol in a diesel? What to do in minute one Work through the following first, in this order. - Keys out of the ignition. Switching your ignition on can be all it takes to prime the system, and priming draws petrol out of the tank toward the parts it harms. Leave the car off completely. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mix. - Hazards on. If you're at all close to moving traffic, make the vehicle simple to see before you do anything else. - The attendants will generally help you roll it away from the pump. Ask, and roll it by hand — never on your engine, even for a few yards. - Which fuel, and about how much? Your receipt answers that, and that's where our first question starts. Don't bin it. Realised on the move? Get off at the next junction if you're on the M60, under 5 miles from Mossley Brow, and stop somewhere safe — not at the services further on. Stage one comes after that. ## Has it run yet? The fork in every Mossley Brow fuel drain Everything after this stage rests on one answer. Motor never run at all? - Only that tank has petrol in it for now. - Where the car sits is normally where the work happens: a drain, then a flush. - Being here is as good as it gets — which is the entire point of step one. If your motor has run, even briefly: - Some petrol has left that tank already, gone through your filter, and reached the fuel lines. - Run it farther and the petrol reaches the injectors, having gone through your pump first. - The further it went, the larger the job — your lines, your filter, and now and then more besides. Diesel keeps the high-pressure fuel pump and the fuel injectors lubricated as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left still, damages nothing. Once it's pumped, petrol starts grinding whatever moves it. ## Calling about petrol in a diesel from Mossley Brow: what to have ready A little planning is the difference between a technician that finds you and a technician that goes round. - The ideal place to start is a postcode — one starting OL5 0 — for where you are. - The street or the car park. A road name is a help — Mountain Street, or wherever you have stopped. - What a car park serves is the quickest way to find it, and so say the landmark — like the one at Co-op Food. - The make and model of your car, and the fact it is a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Mossley Brow, and so say which. - 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 hard. - Whose vehicle it is. Some hire or company contracts want the owner to authorise this work, and that's easier settled before our technicians arrive than after. Then phone 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick as well. ## Waiting for a fuel drain around Mossley Brow: what to do Hold to these: well-intended help does the harm during the wait. - Where your car has stopped settles where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - A kind passer-by does not start it. Nor does anybody wanting to check it still does the trick, or moving it a couple of yards. - Additives stay in the boot. Injector cleaner and two-stroke oil draw none of that petrol out once more. - A DIY drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous besides. - Not for the radio, not for your windows: the ignition remains off. ## Van arrived? The fuel drain, one step at a time - Fuel, quantity, whether it's run: those replies decide this job, and that is why we give a price after them rather than before. - Out of the tank comes the contaminated mix: the tank is drained. - If it ran, your lines are holding petrol that has shifted beyond that tank — so they are rinsed. - Then your filter: replaced where there's a usable one, cleared where there is not. - Clean diesel in, and the fuel system primed. - The start. With new diesel in and your system primed, it is fired up and tested to make sure it runs properly. Your car has fresh diesel running through it before our engineers go. It's very uncommon for a vehicle noticed soon to be left with long-term damage, and normal driving resumes right away. ## Mossley Brow, after the fuel drain: back on the road - Drive normally. There's nothing unusual to do after it has been started on clean fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us a second time. - An insurer, a fleet manager or a hire firm may ask what was done, so hold on to the paperwork. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Mossley Brow and where it is Mossley Brow is a suburban area in Greater Manchester, situated near the River Tame and close to the town of Mossley.
