Here Is What Happens Whatever you do, don't switch your engine on, even briefly, to move the vehicle. Stop; leave the car off. Petrol in a diesel that hasn't been run is typically a drain and a flush, done where the car stands, and what happens in the coming few minutes decides that far more than anything else. Here is the order of things from here, wherever you are in West Side. ## Petrol in a diesel? What to do in minute one Work through the following in sequence, before you do anything else. - Ignition off, keys out. Turned on, the ignition can prime the system — and priming is what draws petrol out of your tank towards the parts it harms. - Do not top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mix. - Being seen comes first beside moving traffic: put your hazards on, and only then deal with anything else. - Off the petrol pump by hand. At a forecourt, get the staff to help you roll it away from the petrol pump. Do not crank it to move it, however short the distance. - Keep the till receipt. It shows which fuel got in and about how much, which is the first thing we'll ask. Still driving when you noticed? Come off the M4 at the next exit if that's where you are, under 15 miles from West Side, and pull over somewhere sensible instead of pushing on to the services. Then begin at stage one. ## Has it run yet? The fork in each West Side fuel drain One answer is what everything after this point depends on. If it has not once been started: - No place but that tank: that is where the petrol still is. - Normally it's emptied and cleaned just where your car stands. - Being here is as good as it gets — which is the whole point of step one. Run at all, even for a second: - Some petrol has left your tank already, gone through your filter, and got into the lines. - The high-pressure fuel pump and the fuel injectors get it on a bigger run. - Mileage is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps the high-pressure pump and the fuel injectors lubricated as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. Petrol sitting in a tank damages nothing. Move that petrol, though, and it grinds down the very parts doing the moving. ## West Side, petrol in a diesel: have these prepared before you call A little preparation is the difference between a van that finds you and a van that goes round. - Where you have stopped. A postcode beginning NP13 3 is the best start. - Give the road — Parsons Row or wherever you have stopped — or the car park. - Car parks are found more easily by what they serve: tell us the one outside Co-op Food, and it's simple. - That it is a diesel, plus the make and model of your car. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own West Side page. - How much. Litres from your receipt, or how long the nozzle was in. - The distance it covered, and how hard, if it has run at all. - Sort who owns your car before our engineers get there: some hire or company contracts want the owner to approve the work, and that is faster first. Call 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use . ## West Side fuel drain on its way? Whilst you wait During the wait, the harm comes from well-intended help — which is why these count. - Your safety comes before the car. Somewhere dangerous? Get away from the traffic and wait away from it. Fine where it sits? Stay with it. - A helpful passer-by doesn't start it. Nor does anyone checking it still works, or rolling it a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it gets that petrol back out. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself. - Leave your ignition off — your windows and the radio too. ## Van arrived? The fuel drain, one stage at a time - Fuel, volume, whether it has run: the answers set the job, and that is why you get a quote after them instead of before. - Next that tank is cleared, and the tainted fuel comes out. - If it ran, the fuel lines are carrying petrol that has shifted beyond the tank — so they are cleaned. - Then the filter: swapped where there's a usable one, cleared where there is not. - Priming comes after fresh diesel is in. - First start on new diesel. Once priming is done, the motor is fired up and our technicians make sure that it runs correctly. Our engineers wait until it's running on new diesel. When it has been caught quickly, permanent damage is very rare, and the car goes back to normal driving straight away. ## West Side, after the fuel drain: back on the road - Once it has been started on clean fuel, there's nothing unusual to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and ring us again. - An insurer, a fleet manager or a hire firm may ask what was done, so hold on to the documents. - Check the label on the petrol pump next time, not the colour of its handle. ## About West Side West Side is a suburban area in Blaenau Gwent, situated on the riverside at an elevation of 282 metres.
