The next few minutes determine it far more than anything else: petrol in a diesel that has not run normally comes down to clearing and cleaning, right there. From here on, step by step, wherever you are in The Greaves: ## Engine off: minute one with petrol in a diesel Go through these in sequence, before you do anything else. - The keys out of your ignition. Turning your ignition on can be all it takes to prime the fuel system, while priming pulls petrol out of the tank towards the components it damages. Keep the car off completely. - Topping up with diesel seems like it thins the problem. It doesn't: nothing comes out, and the tank just carries more of the same. - Hazard lights on. If you are anywhere near moving traffic, make the vehicle easy to see before you do anything else. - However short the way, starting it to move it is the thing to avoid. On a forecourt, roll it away from the petrol pump by hand instead, and ask the attendants to lend a hand. - Which fuel, and roughly how much? The receipt answers that, and that is where our questions start. Don't bin it. If you were still on the move when you noticed, pull over somewhere safe instead of pushing on for the services — on the M6, under a mile from The Greaves, that means the next junction. Step one follows. ## The fork in each The Greaves fuel drain: has it run yet? One answer is what everything after this point rests on. If the engine has not run at all: - Just that tank has petrol in it so far. - Draining and flushing, on the spot, is usually all of that. - Stage one counts for exactly this reason: it is the best spot to be in. Run at all, however briefly: - Out of that tank, past the fuel filter, into the lines: that's how far that petrol has got. - Run it further and the petrol gets to the injectors, having gone through your fuel pump first. - The further it went, the larger this job — the fuel lines, the filter, and sometimes more besides. The line falls there because diesel lubricates the high-pressure fuel pump and the fuel injectors on its way through them — and petrol does not. In that tank, left alone, petrol harms nothing. Petrol being pumped is grinding down the components that shift the car. ## The Greaves, petrol in a diesel: have these ready before you call Prepare a little, and the van finds you instead of circling. - Where you are. A postcode beginning LA1 4 is the ideal place to start. - A road name helps: Hastings Road, say, or whatever street you have stopped in. A car park does the trick too. - What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Spar. - Make and model of the car, and the fact it is a diesel. - Say which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for The Greaves. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - If it has run, how far and how hard — and if it's run at all. - Whose vehicle it is. Some hire or company agreements want the owner to approve this work, and that's quicker settled before our technicians turn up than after. Ring 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain around The Greaves Help, however well meant, is the thing that does the damage whilst you wait. So stick to these. - Safety before the car. If it has stopped somewhere unsafe, get yourself away from the traffic and wait away from it. If it is safe where it stands, wait with it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that takes the petrol back out. - No home-made emptying. Siphoning petrol into a can at the kerbside is hazardous, and it leaves the fuel that has already gone beyond your tank. - Even the radio or the windows are not worth turning the ignition on for. ## The fuel drain, step by step, once the van arrives - Fuel, quantity, whether it's run: the replies set the job, and that is why you get a price after them instead of before. - Then the tank is cleared, and the polluted fuel comes out. - Your lines are flushed. If it ran, the petrol has moved beyond that tank, and the fuel lines are carrying it. - Your filter is seen to. Cleared, or swapped where the car has a usable one. - Fresh diesel goes in, then the fuel system is primed. - The start. With new diesel in and your system bled, it is started and tested to be sure it runs correctly. The car has new diesel running through it before our engineers go. The vehicle goes back to normal use straight away, and long-term damage is very rare if it has been noticed quickly. ## Back on the road around The Greaves after the fuel drain - Nothing unusual is needed after a start with clean diesel — normal driving is all. - Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot. - The work may come up later with a hire firm, an insurer or a fleet manager. Hold on to your documents. - Read the label on the petrol pump next time, not the colour of its handle. ## About The Greaves and where it is The Greaves is a suburban area located on the outskirts of Lancaster in Lancashire, situated near the coast at an elevation of around 45 metres.
