Engine off. Leave the vehicle like that — no second on, no moving it at all. Cleared then flushed, just where it sits: that's usually all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes to come far more than on anything else. Below is the order from this point, wherever in Mossend you are. ## Petrol in a diesel? What to do in minute one Do these first, in this order. - Keys out of your ignition. Turning your ignition on can be enough to prime your fuel system, while priming draws petrol out of the tank towards the parts it damages. Keep it off altogether. - Topping up with diesel sounds like it thins the trouble. It doesn't: nothing gets out, and the tank just holds more of the same. - Visibility comes first near moving traffic: put the hazard lights on, and only then think about anything else. - However short the distance, starting it to shift it is the mistake. On a forecourt, push the vehicle clear of the petrol pump by hand instead, then ask the attendants to lend a hand. - Keep the till receipt. It says which fuel got in plus roughly how much, which is the first thing we will ask. Noticed on the move? Get off at the next exit if you are on the M8, under 3 miles from Mossend, and stop somewhere sensible — not at the services further on. Step one starts after that. ## Every Mossend fuel drain starts here: has the engine run? Everything after this point depends on one answer. If it has not once been started: - No place but that tank: that is where that petrol yet is. - Usually it is emptied and purged right where the car stands. - This is the best case — which is the whole point of step one. If the motor has run, even briefly: - Out of the tank, through the fuel filter, into the lines: that's how far the petrol has got. - A longer run takes it all the way to the high-pressure pump and your injectors. - The farther it went, the bigger the job — the lines, the fuel filter, and sometimes more besides. Diesel keeps the high-pressure fuel pump and your injectors oiled as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. In your tank, sitting still, petrol harms nothing. Pump the petrol, though, and it grinds down the very parts doing the moving. ## Mossend, petrol in a diesel: have these prepared before you call Get ready a little, and the technician finds you instead of circling. - The best start is a postcode — one beginning EH55 8 — for where you are. - The road or the car park. A road name is a help — Westwood View, or wherever you have pulled up. - Or the landmark. A car park is easier to find by what it serves, like the one outside Scotmid. - Tell us what the car is — make, model — and check it's diesel. - What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Mossend, so say which. - How long the nozzle was in, or the litres from the receipt — either gives us how much. - Whether it's run. Then if it has, how far and how hard. - The owner may have to approve the work under some hire or company agreements — so it is quicker to settle whose vehicle it is before we get there. Then call 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick as well. ## Mossend fuel drain on its way? While you wait Stick to these: kindly meant help causes the damage during the wait. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic and wait away from it. If it is safe where it sits, stay with it. - Nobody — however kind — starts it, whether to see if it runs or to move your car a short way. - None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - A home-made drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous too. - Even the radio or the windows aren't worth switching your ignition on for. ## Step by step: the fuel drain when the van arrives - The price comes after three queries, not before them — what was put in, how much, and if it has run — since those answers set this job. - Out of the tank comes the contaminated blend: your tank is emptied. - Purging your lines comes next, since a motor that ran has petrol past your tank, inside the fuel lines themselves. - The filter is dealt with. Cleared, or changed where the car has a workable one. - Priming follows once clean diesel is in. - The first start on fresh diesel. When priming is done, your engine is started and our engineers make sure that it runs properly. Until it runs on fresh diesel, our technicians remain with it. Long-term damage is very unusual when it has been noticed soon, so the vehicle can go straight back to normal use. ## Once the fuel drain is done: driving in Mossend a second time - Nothing unusual is needed after a start with fresh diesel — ordinary driving is all. - Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - An insurer, a fleet manager or a hire company may ask what was carried out, and so keep the paperwork. - Next time, go by the petrol pump's label instead of the colour of its handle. ## About Mossend and where it is Mossend is a village in West Lothian, situated on the riverside at an elevation of 161 metres.
