Cleared then cleaned, right where it sits: that's normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward depends on the minutes to come more than on everything else. Anywhere you are in Weldon, this is how things run from here. ## Petrol in a diesel, engine off — the first minute Go through the following in sequence, before you do anything else. - The 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. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same mixture. - Close to passing traffic? Then the hazard lights go on before everything else, and so the car is easy to spot. - By hand, never on the engine: that is how it comes off the petrol pump. Ask the forecourt staff to help you push, however short the distance. - Keep your receipt: the grade and the rough amount are printed on it, and they're what we ask for first. If you were still on the move when you realised, pull over somewhere sensible rather than pushing on for the services — on the Great North Road, under 15 miles from Weldon, that means the next exit. Stage one follows. ## Every Weldon fuel drain starts here: has your engine run? What comes next turns on one answer, and only one. Engine never run at all? - No place but that tank: that is where the petrol still is. - Normally it's drained and cleaned right where your car is. - Being here is as good as it gets — which is the entire point of stage one. Engine run, however for a moment? - The fuel lines and the filter now hold petrol pulled out of your tank. - On a longer run it has reached your high-pressure pump as well as the injectors. - The job grows with the distance — lines purged, filter seen to, occasionally more. Why the line falls there: diesel lubricates your high-pressure pump as well as the injectors as it passes through them, and petrol doesn't. A tank of petrol, left alone, hurts nothing. The parts that shift it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Weldon: what to have prepared Prepare a little, and the van finds you rather than circling. - Where you have stopped. A postcode starting NN17 3 is the ideal place to start. - The street or the car park. A road name helps — Stamford Road, or wherever you have stopped. - What a car park serves is the easiest way to find it, and so mention the landmark — like the one outside Asda. - The car. Make, model, plus that it is a diesel. - Which was put in matters: AdBlue is a separate job from petrol, plus Weldon has a page just for that. So say. - The quantity: the receipt's litres, or else how long you had the nozzle in. - Has it run? If so, tell us how far it got, and the way it was driven. - The owner may have to approve this work under some hire or company agreements — which is why it is quicker to settle whose car it is before our engineers arrive. Then ring 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick too. ## Waiting for a fuel drain in Weldon: what to do Stick to these: well-meant help does the harm during the wait. - Safety before the car. If it has stopped somewhere dangerous, get yourself away from the traffic then wait away from it. If it is safe where it sits, wait with it. - A kind passer-by does not crank it. Nor does anyone wanting to check it still works, or rolling it a few yards. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays put regardless. - Ignition stays off. Even for the radio or your windows. ## Van arrived? Your fuel drain, one step at a time - First, three questions: which fuel got in, the amount, and has it run? Those replies set this job, and so our quote follows them. - That tank is cleared. The polluted mixture comes out of that tank. - If it ran, the fuel lines are carrying petrol that has moved beyond that tank — so they are flushed. - Cleaned, or replaced if the vehicle has a usable one: the fuel filter is seen to next. - Clean diesel goes in, then the fuel system is primed. - First start on clean diesel. When bleeding is finished, your engine is fired up and our technicians make sure that it runs correctly. We remain until it's running on clean diesel. If it has been caught soon, long-term damage is very rare, and the car goes back to normal driving at once. ## Once your fuel drain is done: driving around Weldon again - Nothing unusual is needed after a start with fresh diesel — usual 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 matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Weldon and where it is Weldon is a village in Northamptonshire, situated in the East Midlands region of England, with a population of around 1454 people.
