Here Is What Happens Whatever you do, never switch the engine on, even briefly, to move the car. Pause; leave the vehicle off. Petrol in a diesel that hasn't been run is typically a drain and a flush, done right where your vehicle sits, and what happens in the coming few minutes decides that far more than anything else. Below is the order from this point, anywhere around Brownside you are. ## Minute one: petrol in a diesel, engine off Go through these in order, before you do anything else. - Pull the keys out. Even the ignition by itself can prime your fuel system, drawing petrol out of the tank to exactly the components it damages, and so keep the car alone completely. - A fuller tank of the same mix is all adding diesel leaves you, because it removes nothing. So no extra diesel. - Close to passing traffic? Then the hazards come on before everything else, so your car is simple to see. - Off the petrol pump by hand. On a forecourt, ask the staff to help you push the vehicle away from the pump. Don't crank it to move it, however short the way. - Hold on to your receipt: the fuel and the rough amount are printed on it, and they are what our engineers ask about first. On the M65, under 3 miles from Brownside, the next junction is the location to leave the car; anywhere, the first safe place to stop. Don't push on to the services. Then go back to step one. ## Every Brownside fuel drain starts here: has the engine run? From this stage on, everything hinges on a single answer. Engine not run at all? - Just your tank has petrol in it so far. - Normally it is drained and cleaned right where the car is. - No place is better, and it is why the first stage matters so much. Engine run, even briefly? - Out of the tank, past the filter, into the lines: that's how far the petrol has travelled. - On a bigger run it has reached your high-pressure pump and your injectors. - The job expands with the miles — lines flushed, filter dealt with, occasionally more. Petrol does not lubricate. Diesel does, oiling your high-pressure pump and injectors as it passes through, which is why the line falls where it does. In that tank, sitting still, petrol does no harm. As soon as it is pumped, petrol begins wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Brownside Prepare a little, and the van finds you instead of circling. - BB10 3 plus the remainder of the postcode is the best way to start telling us where you are. - Give the road — Crookhalgh Avenue or wherever you have pulled up — or the car park. - Car parks are found most easily by what they serve: say the one at Londis, and it is straightforward. - The car. Make, model, plus that it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Brownside page. - How long the nozzle was in, or the litres from the receipt — whichever gives us how much. - Has it run? If so, say how far it went, and the way it was driven. - Whose car it is. Some hire and company agreements want the owner to approve this work, and that is easier settled before we arrive than after. Then phone 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too. ## The wait for a Brownside fuel drain, and what to do in it Help, however well meant, is the thing that does the harm while you wait. So hold to these. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards. - None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - A home-made drain leaves your fuel that has already gone beyond the tank, and siphoning petrol by the road is risky besides. - Leave your ignition off — your windows and the radio too. ## Step by step: your fuel drain when our van gets there - Three queries. What got in, how much, and if it has run. The replies decide this job, which is why our price comes after them and not before. - Next that tank is emptied, so the tainted fuel is taken out. - Petrol that has moved beyond that tank travels in your lines once it ran, and your lines are rinsed to shift it. - Where the vehicle has a workable filter, it is changed; if not, cleared. - Fresh diesel in, and the system primed. - The first start on new diesel. Once bleeding is done, your engine is fired up and our technicians check that it runs properly. Only once it's running on clean diesel do our technicians head off. It's very rare for a vehicle caught quickly to be left with long-term damage, and normal driving resumes at once. ## Once the fuel drain is done: driving around Brownside again - After it's been started on fresh fuel, there's nothing special to do: 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 call us back. - The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, check the pump. The label, not the colour of its handle. ## About Brownside and where it is Brownside is a suburban area situated on the edge of a lake in Lancashire, with a mix of semi-detached housing and a population of around 2403 residents.
