Engine off. Leave it that way — no second on, no shifting it at all. Emptied and rinsed, right where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes ahead far more than on everything else. Here's the sequence of things from here, anywhere you are in Brightside. ## Petrol in a diesel? What to do in minute one First, the following — in this sequence. - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of the tank towards the components it harms. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture. - Being seen comes before the rest near moving traffic: switch the hazards on, and only then think about anything else. - Off the pump by hand. On a forecourt, ask the staff to help you roll the car clear of the petrol pump. Don't start it to shift it, however short the way. - Hold on to the till receipt: the grade and the rough amount are written on it, and they're what our technicians ask about first. Still driving when you realised? Come off the Tinsley Viaduct at the next junction if that is where you are, under 3 miles from Brightside, and stop somewhere safe rather than pushing on to the services. Then start at step one. ## Has it run yet? The fork in every Brightside fuel drain Everything after this stage rests on one answer. If it has never been started: - The petrol is still in the tank and nowhere else. - Draining and flushing, on the spot, is normally the whole job. - Stage one matters for exactly this reason: it is the best spot to be in. If the motor has run, even for a moment: - Some petrol has left the tank by now, passed through the filter, and reached your lines. - Run it further and the petrol gets to the injectors, having gone through the fuel pump first. - The job grows with the distance — lines rinsed, filter sorted, sometimes more. The line falls there because diesel protects the high-pressure fuel pump and the fuel injectors on its way through them — and petrol does not. In that tank, sitting still, petrol does no harm. Move the petrol, though, and it wears the very parts doing the moving. ## Before you call about petrol in a diesel in Brightside: what our technicians need Prepare a little, and the van finds you rather than circling. - The ideal place to start is a postcode — one starting S4 8 — for where you have stopped. - Name the street — Chambers Lane or wherever you have stopped — or the car park. - Name a car park by what it serves — the one at Boldspirit Enterprise Ltd, for example — and it's much quicker to find. - Tell us what the vehicle is — make, model — and confirm it's diesel. - Tell us which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Brightside. - The amount: the receipt's litres, or otherwise how long you had the nozzle in. - If it has run, how far and how heavily — as well as if it has run at all. - The owner may have to approve this work under some hire and company agreements — which is why it is faster to settle whose motor it is before our engineers get there. Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere — works too. ## The wait for a Brightside fuel drain, and what to do in it The wait is where kindly meant help does the damage. Stick to these. - Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Safe where it stands? Stay with it. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: nobody starts it. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains put anyway. - Keep the ignition off — the windows and your radio too. ## The fuel drain, step by step, after our van gets there - Our price comes after three questions, not before them — what was put in, how much, and if it's run — because those replies set the job. - The tank is cleared. The tainted blend comes from that tank. - Flushing the lines follows, because a vehicle that ran has petrol past the tank, inside the lines themselves. - The filter is seen to. Cleared, or changed where your car has a usable one. - Clean diesel in, and your system primed. - Starting the car. Once the fuel system is bled with clean diesel, our technicians start the car and make sure it runs properly. Your car has new diesel running through it before our technicians leave. It is very unusual for a vehicle spotted early to be left with long-term damage, and normal use starts again right away. ## After your fuel drain: back on the road in Brightside - Started on fresh diesel, it asks nothing unusual of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then ring us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Read the label on the petrol pump next time, not the colour of the handle. ## About Brightside itself Brightside is a suburban area in South Yorkshire, situated on the River Don and close to the city centre of Sheffield.
