Stop there. Petrol in a diesel that has not been run is normally a simple drain and a flush, done where your vehicle stands, and what you do in the next few minutes determines that more than anything else. From here on, in order, wherever you are around Weston Mill: ## Minute one: petrol in a diesel, engine off First, the following — following this order. - Bleeding the system pulls petrol from your tank toward the components it harms, and switching your ignition on can be all it takes to do that. So your keys get taken out, and your ignition stays off altogether. - Don't top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mix. - Visibility comes before the rest near moving traffic: put the hazards on, and only then deal with anything else. - However short the distance, starting it to move it is the mistake. On a forecourt, roll the car clear of the petrol pump by hand instead, then ask the staff to help. - The first thing we will ask is which fuel you put in and roughly how much — and the till receipt shows both. Hold on to it. Still driving when you noticed? Come off the M5 at the next exit if that is where you are, under 50 miles from Weston Mill, and stop somewhere safe and not pressing on to the services. Then start at stage one. ## Has it run yet? The fork in each Weston Mill fuel drain What comes after this rests on one answer, and only one. Not run, not even briefly: - No place but that tank: that's where the petrol still is. - Where the car sits is normally where the work happens: a drain, then a flush. - Stage one matters for precisely this reason: it's the best spot to be in. If the motor has been run, even briefly: - Some petrol has left your tank already, passed through the filter, and reached the fuel lines. - The high-pressure pump and the fuel injectors see it too on a longer run. - Lines flushed, your filter dealt with, and sometimes more: the job grows as the distance does. Diesel keeps the high-pressure pump and the injectors lubricated as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. Petrol sitting in a tank damages nothing. As soon as it is pumped, petrol starts wearing down whatever moves it. ## Before you call about petrol in a diesel around Weston Mill: what our technicians need Get ready a little, and the van finds you rather than circling. - Where you have stopped. A postcode starting PL5 1 is the best start. - Wherever you have pulled up, the road's name is useful — whether that's Churchway or somewhere else — and so does the name of a car park. - Car parks are found more easily by what they serve: say the one outside Lidl, and it's simple. - That it is a diesel, plus the make and model of the car. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Weston Mill page. - The amount: your receipt's litres, or else how long you had the nozzle in. - Whether it has run. Then if it has, how far and how heavily. - Hire or company car? Some agreements need the owner's authorisation for the work, and getting it before our engineers turn up is faster than afterwards. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Weston Mill fuel drain on its way? Whilst you wait Hold to these: well-meant help does the harm during the wait. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a few yards. - Something from your boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - Siphoning petrol into a can by the kerbside is hazardous — and it also leaves whatever fuel has already gone beyond that tank. Do not drain the vehicle yourself. - Even the radio or the windows are not worth turning your ignition on for. ## Van arrived? The fuel drain, one step at a time - Three queries. What was put in, how much, and if it's run. Those replies shape this job, which is why the price comes after them but not before. - Next your tank is cleared, so the tainted fuel comes out. - The fuel lines are rinsed. If it ran, that petrol has moved beyond that tank, and your lines are carrying it. - Then the filter: replaced where there's a usable one, cleared where there is not. - Bleeding your system follows once clean diesel is in. - We fire it up only after clean diesel has gone in and bled the fuel system, then make sure that it's running properly. Till it runs on new diesel, our engineers stay with it. Your car goes back to normal use right away, and long-term damage is very rare when it has been caught soon. ## After the fuel drain: back on the road in Weston Mill - Once it has been started on fresh fuel, there's nothing special to do: drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then call us back. - The work may matter later with a hire company, an insurer or a fleet manager. Keep the documents. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Weston Mill Weston Mill is a suburban area located on the outskirts of Plymouth in Devon, sitting at an elevation of 46 metres near the coast.
