Motor off. Leave the car that way — no moment on, no shifting it anywhere. The coming few minutes decide it more than anything else: petrol in a diesel that has not run generally comes down to draining then rinsing, on the spot. Here is the sequence of things from now, wherever you are in Leiston. ## Motor off: minute one with petrol in a diesel Work through these in sequence, before you do anything else. - Keys out of the ignition. Turning your ignition on can be all it takes to prime the system, and priming pulls petrol out of the tank towards the parts it damages. Keep it off completely. - Topping up with diesel sounds like it dilutes the issue. It does not: nothing gets out, and that tank just carries more of the same. - Near passing traffic? Then your hazards come on before anything else, so your car is simple to see. - Off the petrol pump by hand. At a forecourt, get the attendants to help you roll the car clear of the pump. Do not start the car to move it, however short the distance. - The first thing you will be asked is which fuel went in and about how much — and the receipt says both. Hold on to it. Noticed on the move? Get off at the next exit if you're on the M11, over 50 miles from Leiston, and stop somewhere sensible — not at the services further on. Stage one starts after that. ## Has it run yet? The fork in each Leiston fuel drain One answer is what everything after this point rests on. If it has not once been started: - No place but that tank: that is where that petrol yet is. - A drain and flush, on the spot, is normally all of it. - This, here, is the best position to be in, and the whole reason step one counts. If it's been started, even for a second: - The lines and the fuel filter now hold petrol pulled from that tank. - Run it further and that petrol gets to your injectors, having passed through the pump first. - Flushing your lines, your filter seen to, occasionally more: the job grows as the mileage does. Why the line falls there: diesel lubricates the high-pressure fuel pump as well as your injectors as it flows through them, and petrol does not. Petrol resting in a tank damages nothing. Move the petrol, though, and it grinds down the very parts doing the moving. ## Before you call about petrol in a diesel in Leiston: what our engineers need A little planning is the difference between a technician that finds you and a technician that goes round. - The ideal start is a postcode — one beginning IP16 4 — for where you are. - Give the road — High Street or wherever you have pulled up — or the car park. - Car parks are located most easily by what they serve: tell us the one at East of England CO-OP, and it's straightforward. - That it is a diesel, along with the make and model of the car. - Say which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Leiston. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - Whether it's run. Then if it has, how far and how hard. - Sort who has your car before we turn up: some hire or company contracts want the owner to approve the work, and that is quicker beforehand. Next, 0333 366 0103. Not pressing, the vehicle left at home with nowhere to be? Then works as well. ## Leiston fuel drain on its way? Whilst you wait Help, however well meant, is what does the damage while you wait. So hold to these. - Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic then wait away from it. Fine where it sits? Wait with it. - A kind passer-by does not start it. Nor does anyone wanting to check it still works, or moving it a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets the petrol back out. - No home-made emptying. Siphoning petrol into a can at the kerbside is risky, and it leaves the fuel that has by now gone beyond the tank. - Even your radio or the windows aren't worth switching your ignition on for. ## When the van arrives: the fuel drain, step by step - Fuel, quantity, whether it's run: the answers decide this job, and that's why you get a quote after them rather than before. - Next that tank is drained, and the contaminated fuel comes out. - Petrol that has moved beyond your tank travels in the lines once it ran, and the fuel lines are rinsed to shift it. - Then the fuel filter: changed where there's a usable one, cleared where there's not. - Your system is primed on fresh diesel. - Starting up. When your system is bled with new diesel, our engineers start the engine and check it runs correctly. Your car has fresh diesel running through it before we head off. The car returns to normal driving straight away, and permanent damage is very uncommon if it has been spotted soon. ## Leiston, after the fuel drain: back on the road - Drive normally. There's nothing special 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 once more. - The work may come up later with a hire company, an insurer or a fleet manager. Hold on to the paperwork. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Leiston, for a moment Leiston is a small town on the Suffolk coast, situated near the villages of Aldringham and Knodishall.
