Here Is What Happens Not for a moment, and not to move it: your engine stays off. Stop there. The coming few minutes determine it more than anything else: petrol in a diesel still unrun normally amounts to clearing and flushing, right there. Here's the order of things from now, anywhere you are around Aston. ## Petrol in a diesel? What to do in minute one In this sequence, all before everything else: - Ignition off, keys out. Switched on, your ignition can prime your system — and priming is what draws petrol out of your tank into the parts it damages. - Don't top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mixture. - Hazard lights on. If you're anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - By hand, not under the motor: that's how it comes off the pump. Get the forecourt staff to help you push, whatever the miles. - Keep the till receipt. It says which fuel was put in plus about how much, which is the first thing we will ask. On the M42, under 25 miles from Aston, the next junction is the place to come off; elsewhere, the first sensible place to stop. Do not push on to the services. Then go back to step one. ## Each Aston fuel drain starts here: has your motor run? One answer is what everything after this stage rests on. Not run, not even briefly: - Just your tank has petrol in it for now. - The job is a drain and a flush, normally done where your car stands. - This is the best case — which is the whole point of stage one. If your engine has run, even for a moment: - The lines and the filter already hold petrol drawn out of your tank. - Run it further and the petrol reaches your injectors, having passed through your pump first. - The job expands with the miles — lines cleaned, filter seen to, occasionally more. That line falls there because diesel lubricates the high-pressure fuel pump and your injectors on its way through them — and petrol doesn't. A tank of petrol, left still, hurts nothing. Move the petrol, though, and it wears the very parts that move it. ## Aston, petrol in a diesel: have these ready before you call Whether the technician goes round or finds you depends on a little preparation. - DE6 5 and the rest of the postcode makes the ideal way to start telling us where you are. - Name the road — Aston Lane or wherever you have pulled up — or the car park. - Car parks are found most easily by what they serve: tell us the one at The Co-operative Food, and it's straightforward. - That it is a diesel, along with the make and model of your car. - Say which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Aston. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - The distance it did, and how hard, if it ran at all. - Whose motor it is. Some hire or company agreements want the owner to authorise this work, and that's quicker settled before our technicians turn up than after. Phone 0333 366 0103 once you have got that ready — or, if the vehicle is at home, going nowhere, use . ## Waiting for a fuel drain around Aston: what to do The wait is where well-meant help does the damage. Stick to these. - Safety before your car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it's safe where it stands, stay with it. - Nobody — however kind — starts it, whether to see if it runs or to shift your car a short way. - None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - Siphoning petrol into a can by the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Do not drain it yourself. - Ignition stays off. Even for your radio or the windows. ## Step by step: the fuel drain when the van gets there - Fuel, amount, whether it has run: those answers decide this job, and that is why we give a price after them rather than before. - Then that tank is cleared, so the contaminated fuel comes out. - If it ran, your lines are carrying petrol that has shifted beyond your tank — so they are purged. - The filter is seen to. Cleared, or swapped where the vehicle has a serviceable one. - Clean diesel in, and the system primed. - The start. With clean diesel in and your system bled, it's started and tested to confirm it runs properly. Only when it's running on new diesel do our technicians leave. The car goes back to normal use at once, and long-term damage is very uncommon if it has been noticed soon. ## After the fuel drain: back on the road around Aston - Drive normally. There's nothing unusual to do after it's been started on fresh fuel. - 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. - Keep your paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Aston itself Aston is a small hamlet in Derbyshire, situated inland at an elevation of 69 metres, approximately 11.8 miles from Derby.
