Emptied and rinsed, right where it sits: that's usually all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes to come more than on anything else. Here's the order of things from here, anywhere you are around Brownston. ## Petrol in a diesel, engine off — the first minute Before anything else, these — following this order. - Pull the keys out. Even the ignition by itself can prime your fuel system, pulling petrol out of the tank to precisely the parts it damages, and so keep the vehicle off entirely. - No diesel on top. More fuel in removes none of the petrol — it only leaves you with extra of the same mixture. - Get the car simple to see before anything else — hazard lights on — if there is traffic going past anywhere close to you. - The staff will generally help you roll it clear of the petrol pump. Let them, then roll it by hand — never under the motor, even for a couple of yards. - Hold on to your receipt. It says which fuel was put in and about how much, which is the first thing we will ask. Still on the move when you realised? Come off the M5 at the next junction if that's where you are, under 25 miles from Brownston, and pull over somewhere safe rather than pushing on to the services. Then start at stage one. ## Brownston fuel drain: has your engine run yet, or not? Everything after this stage rests on one answer. If the motor has not run at all: - All the petrol remains in your tank, and just there. - Where the car stands is usually where the work is done: a drain, then a flush. - Step one matters for precisely this reason: it is the best spot to be in. Run at all, however briefly: - Some petrol has left your tank already, passed through your filter, and reached your lines. - On a longer run it has got to the high-pressure fuel pump as well as your injectors. - The job expands with the miles — lines purged, filter sorted, sometimes more. Petrol does not lubricate. Diesel does, protecting your high-pressure pump and injectors as it passes through, which is why the line sits where it does. Petrol sitting in a tank harms nothing. Petrol being pumped is grinding down the components that shift the vehicle. ## Brownston, petrol in a diesel: have these prepared before you call A technician that circles versus a van that finds you: a little planning is the difference. - TQ10 9 and the remainder of the postcode makes the ideal way to begin telling us where you are. - The street or the car park. A road name is a help — Willing Cross, or wherever you have pulled up. - Car parks are found more easily by what they serve: say the one outside The Co-operative Food, and it is simple. - That it's a diesel, along with the make and model of your vehicle. - Say which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Brownston. - About how much — in litres from your receipt, or by how long the nozzle stayed in. - If it's run, how far plus how hard — and whether it has run at all. - Sort who owns your car ahead of when we get there: some hire or company agreements want the owner to authorise this work, and that is faster first. Call 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Brownston: what to do The wait is where well-meant help does the damage. Stick to these. - Safety before the car. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it's safe where it stands, stay with it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time. - Siphoning petrol into a can at the kerbside is risky — and it also leaves whatever fuel has already gone beyond your tank. Do not drain the car yourself. - Even the radio or the windows are not worth switching the ignition on for. ## Van arrived? Your fuel drain, one step at a time - First, three queries: which fuel was put in, the amount, and has it run? Those replies set the job, and so the price follows them. - Your tank is drained. The polluted mix comes from your tank. - Petrol that has shifted beyond the tank travels in the lines once it ran, and the fuel lines are cleaned to clear it. - Where the car has a workable filter, it's changed; if not, cleared. - Fresh diesel in, and the system primed. - Starting up. When your system is primed with clean diesel, our technicians fire it up and confirm it runs smoothly. Till it runs on fresh diesel, we stay with it. If it has been noticed quickly, long-term damage is very rare, and the vehicle goes back to normal use at once. ## After the fuel drain is done: driving around Brownston once more - Nothing unusual is needed after a start with fresh diesel — ordinary driving will do. - Pull over and ring us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so keep the documents. - Check the label on the petrol pump next time, not the colour of the handle. ## About Brownston and where it is Brownston is a small hamlet in Devon, situated inland at an elevation of 119 metres, and is located near the villages of Rattery and Dean Prior.
