Here Is What Happens Not for a moment, and not to move it: the engine remains off. Pause there. Cleared then rinsed, just where it sits: that's generally all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes to come more than on anything else. Here is the sequence of things from now, wherever you are in Banwell. ## Petrol in a diesel? What to do in minute one In this sequence, and before anything else: - Bleeding the system pulls petrol from the tank towards the parts it harms, and turning the ignition on can be all it takes to do that. So the keys come out, and your ignition stays off altogether. - No diesel on top. More fuel in removes none of that petrol — it just leaves you with extra of the same mixture. - Near passing traffic? Then your hazards come on before everything else, and so the car is simple to see. - The staff will normally help you roll it clear of the petrol pump. Ask, then roll it by hand — never under your engine, even for a few yards. - Keep the till receipt. It shows which fuel got in plus about how much, which is the first thing we will ask. Still on the move when you noticed? Come off the M5 at the next exit if that is where you are, under 3 miles from Banwell, and pull over somewhere safe rather than pressing on to the services. Then start at stage one. ## Banwell fuel drain: has the engine run yet, or not? Everything after this point depends on one answer. Not run, not even briefly: - Only the tank has petrol in it for now. - Normally it's drained and cleaned right where the vehicle is. - Stage one counts for precisely this reason: it is the best position to be in. Run at all, however briefly: - Some petrol has left your tank already, gone through the filter, and reached the fuel lines. - A bigger run takes it all the way to the high-pressure fuel pump and the fuel injectors. - The farther it went, the bigger the job — the fuel lines, the filter, and now and then more besides. Why the line falls there: diesel protects the high-pressure pump as well as the injectors as it passes through them, and petrol doesn't. A tank of petrol, left still, hurts nothing. Move that petrol, though, and it wears the very parts that move it. ## Before you call about petrol in a diesel around Banwell: what we need A van that circles against a technician that finds you: a little preparation is the difference. - Your location: a postcode beginning BS29 6 serves best. - A road name is a help: West Street, say, or whichever street you have stopped in. A car park works too. - What a car park serves is the quickest way to find it, so say the landmark — like the one at Manor Stores. - That it's a diesel, along with the make and model of your vehicle. - Which was put in matters: AdBlue is a separate job from petrol, and Banwell has a page just for that. So say. - The quantity: the receipt's litres, or else how long you held the nozzle in. - Has it run? If so, say how far it went, and how it was driven. - The owner may have to approve this work under some hire and company contracts — which is why it is faster to settle whose car it is before our technicians get there. Phone 0333 366 0103 then. Email works too if it can wait, with your car parked at home, going nowhere. ## Waiting for a fuel drain in Banwell: what to do Help, however well meant, is the thing that does the harm while you wait. So hold to these. - Wait with the car 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. - A kind passer-by doesn't crank it. Nor does anybody wanting to check it still does the trick, or rolling it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of it takes that petrol back out. - No home-made clearing. Siphoning petrol into a can at the kerbside is risky, and it leaves the fuel that has by now gone beyond that tank. - Not for the radio, not for the windows: your ignition stays off. ## Van arrived? The fuel drain, one step at a time - Three queries. What went in, how much, and whether it has run. The answers decide the job, which is why our quote comes after them and not before. - Next your tank is drained, so the tainted fuel is taken out. - Your lines are flushed. If it ran, the petrol has moved beyond that tank, and the lines are carrying it. - The filter is sorted. Cleared, or swapped where the vehicle has a usable one. - Clean diesel goes in, and the fuel system is primed. - The start. With new diesel in and the fuel system bled, it is started and tested to make sure it runs correctly. We stay until it is running on fresh diesel. It's very uncommon for a car noticed quickly to be left with lasting damage, and normal driving resumes at once. ## Back on the road in Banwell after your fuel drain - Drive normally. There's nothing unusual to do after it has been started on clean fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and call us once more. - Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was done. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Banwell Banwell is a small village in Somerset, situated on the riverside at an elevation of 21 metres, with detached housing being the predominant type of accommodation.
