Pause; leave the vehicle off. The next few minutes settle it far more than anything else: petrol in a diesel that has not run normally comes down to clearing then purging, right there. From now on, in order, wherever you are around Seaton Sluice: ## Minute one: petrol in a diesel, engine off Work through these in sequence, first. - Bleeding your fuel system draws petrol from your tank towards the components it damages, and switching your ignition on can be all it takes to do that. So the keys come out, and the ignition remains off completely. - Topping up with diesel sounds like it thins the trouble. It doesn't: nothing gets out, and the tank simply carries more of the same. - Visibility comes first beside moving traffic: switch your hazards on, and only then think about anything else. - The attendants will generally help you push it away from the pump. Let them, and roll it by hand — not under the motor, even for a few yards. - Hold on to your receipt. It shows which fuel got in plus about how much, which is the first thing we will ask. If you were still driving when you realised, pull over somewhere safe instead of pushing on for the services — on the A167(M), under 10 miles from Seaton Sluice, that means the next exit. Step one follows. ## Every Seaton Sluice fuel drain starts here: has your motor run? Everything after this point depends on one answer. If the motor hasn't run at all: - The petrol sits inside that tank, and only there. - A drain and flush, on the spot, is normally the whole job. - This is as good as it gets — which is the whole point of stage one. If your engine has been run, even briefly: - Out of the tank, past the filter, into the lines: that is how far that petrol has travelled. - A bigger run carries it right through to the high-pressure pump and your injectors. - The farther it went, the larger the job — the lines, your filter, and now and then more besides. Diesel keeps your high-pressure pump and the injectors protected as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left alone, hurts nothing. The parts that move it are wearing the moment petrol is being pumped. ## Seaton Sluice, petrol in a diesel: have these prepared before you call A little preparation is the difference between a van that finds you and a van that goes round. - NE26 4 and the rest of the postcode makes the ideal way to start telling us where you are. - Give the street — Collywell Bay Road or wherever you have pulled up — or the car park. - What a car park serves is the easiest way to find it, so say the landmark — such as the one at Londis Shop and Post Office. - The vehicle. Make, model, plus that it is a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Seaton Sluice, and so say which. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - If it's run, how far and how hard — as well as if it has run at all. - The owner may have to approve the work under some hire or company agreements — so it's quicker to settle whose car it is before we get there. Ring 0333 366 0103 next. Writing to is fine too if it can wait, with your car parked at home, going nowhere. ## While you wait for a fuel drain in Seaton Sluice Stick to these: kindly meant help causes the damage during the wait. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety ahead of your car. - A helpful passer-by doesn't fire it up. Nor does anyone checking it still does the trick, or moving it a few yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it takes that petrol back out. - No home-made draining. Siphoning petrol into a can by the roadside is hazardous, and it leaves your fuel that has by now gone beyond the tank. - Keep the ignition off — the windows and the radio included. ## When the van gets there: the fuel drain, step by step - Fuel, amount, whether it has run: the replies decide the job, and that is why you get a price after them instead of before. - Then your tank is cleared, and the contaminated fuel is taken out. - Your lines are purged. If it ran, the petrol has shifted beyond that tank, and your lines are holding it. - Cleared, or swapped if the vehicle has a serviceable one: the filter is dealt with next. - Fresh diesel goes in, then your system is primed. - We fire it up only after new diesel has gone in and bled your system, then check that it is running properly. Until it runs on fresh diesel, we remain with it. Lasting damage is very rare when it has been spotted early, so the vehicle can go right back to normal use. ## After your fuel drain: back on the road in Seaton Sluice - Drive normally. There is nothing unusual to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then ring us back. - The work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork. - Read the label on the petrol pump next time, not the colour of its handle. ## About Seaton Sluice, for a moment Seaton Sluice is a small coastal village in Northumberland, situated near the mouth of the Seaton Burn, with Seaton Sluice being a popular spot for walkers and nature lovers.
