Here Is What Happens Not for a moment, and not for moving it: the motor stays off. Stop there. Emptied then flushed, right where it is: that is generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward depends on the minutes ahead far more than on everything else. What follows is the sequence from this point, anywhere in Coates you are. ## Engine off: minute one with petrol in a diesel In this order, and before everything else: - Pull your keys out. Even your ignition on its own can prime your fuel system, drawing petrol out of the tank to precisely the parts it damages, so leave the car alone entirely. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mix. - Get your car simple to see before anything else — hazards on — if there is moving traffic anywhere close to you. - By hand, not under the motor: that is how it comes off the pump. Ask the forecourt staff to help you push, however short the miles. - Hold on to the receipt. It shows which fuel was put in plus roughly how much, which is the first thing we'll ask. Noticed on the move? Get off at the next junction if you're on the M65, under 5 miles from Coates, and pull over somewhere sensible — not at the services further on. Step one starts after that. ## Has it run yet? The fork in each Coates fuel drain What happens next rests on one answer, and just one. If the motor has not run at all: - No place but your tank: that's where that petrol still is. - Normally it is emptied and cleaned right where your car is. - No place is better, and it is why the first step counts so much. Run at all, however briefly: - Some petrol has left your tank by now, passed through your filter, and got into the fuel lines. - On a bigger run it has reached your high-pressure pump as well as your injectors. - Lines flushed, the filter seen to, occasionally more: the job grows as the mileage does. Diesel keeps the high-pressure fuel pump and the fuel injectors oiled as it runs through them. Petrol offers them nothing, and that is why the line is drawn there. A tank of petrol, left alone, damages nothing. Pump the petrol, though, and it grinds down the very parts that move it. ## What to have ready when you call about petrol in a diesel from Coates A van that circles versus a van that finds you: a little planning is what separates them. - BB18 6 and the remainder of the postcode makes the ideal way to begin telling us where you are. - Wherever you have parked, the road's name is useful — whether that is Ben Lane or somewhere else — and so does the name of a car park. - Or the landmark. A car park is quicker to find by what it serves, such as the one outside Aldi. - The car. Make, model, and that it is a diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Coates, and so say which. - How long the nozzle was in, or the litres on your receipt — either tells us how much. - Has it run? If so, say how far it got, and how it was driven. - Sort who has your car ahead of when our technicians get there: some hire or company contracts want the owner to authorise this work, and doing it quicker beforehand. Next, 0333 366 0103. Not time-critical, the car left at home with nowhere to be? Then works as well. ## Whilst you wait for a fuel drain in Coates In the wait, the harm comes from kindly meant help — so these count. - Where the car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before your car. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: no one starts it. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of that takes that petrol back out. - Siphoning petrol into a can at the roadside is hazardous — and it also leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain. - Leave the ignition off — your windows and the radio included. ## The fuel drain, step by step, once the van gets there - First, three questions: which fuel was put in, the quantity, and has it run? Those replies decide the job, so the price follows them. - Your tank is drained. The polluted mix comes out of your tank. - Petrol that has shifted beyond your tank travels in the fuel lines once it ran, and your lines are rinsed to clear it. - The filter is sorted. Cleared, or replaced where your car has a usable one. - The fuel system is primed on clean diesel. - Our technicians fire it up only after fresh diesel has gone in and bled the system, then confirm that it is running smoothly. The vehicle has clean diesel running through it before we head off. The car returns to normal use at once, and permanent damage is very uncommon when it has been caught early. ## Coates, after the fuel drain: back on the road - Drive normally. There's nothing special to do once it's been started on fresh fuel. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over then call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so keep your documents. - Next time, go by the pump's label rather than the colour of its handle. ## About Coates and where it is Coates is a suburban area in Lancashire, situated on the riverside with a mix of terraced housing and other residential properties.
