Pause there. Drained and cleaned, just where it is: that is usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come more than on anything else. Here's the sequence of things from here, anywhere you are in Rotten Green. ## Motor off: minute one with petrol in a diesel In this sequence, all before anything else: - Keys out of the ignition. Turning your ignition on can be enough to prime the fuel system, and priming draws petrol out of the tank toward the components it harms. Leave the vehicle off altogether. - A bigger tank of the same mix is all topping up leaves you, since it takes out nothing. So no more diesel. - Hazards on. If you are anywhere near moving traffic, make the car easy to see before you do anything else. - By hand, never under the motor: that's how it comes off the petrol pump. Get the forecourt attendants to help you roll, whatever the miles. - Keep the till receipt: the grade and the rough amount are written on it, and they're what our engineers ask about first. If you were still on the move when you noticed, stop somewhere sensible instead of pushing on for the services — on the M3, under a mile from Rotten Green, that means the next exit. Stage one comes next. ## The fork in every Rotten Green fuel drain: has it run yet? From this stage on, everything hinges on a single answer. Engine not run at all? - Only the tank has petrol in it so far. - A drain and flush, on the spot, is usually all of that. - No spot is better, and it is why the first stage matters so much. Run at all, however briefly: - From your tank, through the fuel filter, into the fuel lines: that is how far that petrol has got. - A bigger run takes it right through to the high-pressure pump and your injectors. - The further it went, the bigger this job — the fuel lines, the filter, and sometimes more besides. The reason the line falls there: diesel protects the high-pressure fuel pump as well as your injectors as it passes through them, and petrol doesn't. In that tank, left alone, petrol harms nothing. Once it's pumped, petrol starts wearing whatever moves it. ## Calling about petrol in a diesel from Rotten Green: what to have ready Whether the technician goes round or finds you comes down to a little preparation. - Your location: a postcode starting GU51 1 works best. - Wherever you have parked, the road's name helps — whether that is Micheldever Drive or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one at Morrisons. - Say what your car is — make, model — and check it's diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Rotten Green page. - How much. Litres from the receipt, or how long the nozzle was in. - Has it run? If so, say how far it went, and the way it was driven. - Whose car it is. Some hire or company contracts want the owner to approve this work, and that is easier settled before we arrive than after. Phone 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use . ## Rotten Green fuel drain on its way? While you wait Help, however well meant, is what does the harm while you wait. So hold to these. - Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - A kind passer-by does not crank it. Nor does anybody checking it still does the trick, or moving it a couple of yards. - None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A home-made drain leaves your fuel already gone beyond the tank, and siphoning petrol by the road is hazardous too. - Ignition remains off. Even for your radio or the windows. ## Step by step: your fuel drain when the van arrives - First, three questions: which fuel was put in, the amount, and has it run? Those answers decide this job, so the quote follows them. - Emptying it is how the blend gets taken out of your tank. - Flushing the fuel lines follows, since a motor that ran has petrol past your tank, in the fuel lines themselves. - Your filter is seen to. Cleared, or swapped where the car has a usable one. - Fresh diesel goes in, then the fuel system is primed. - The start-up. With new diesel in and your system bled, it is started and tested to be sure it runs correctly. Our technicians remain until it is running on new diesel. It's very unusual for a car noticed quickly to be left with lasting damage, and normal use starts again at once. ## Back on the road around Rotten Green after your fuel drain - Started on new diesel, it needs nothing unusual of you. Just drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and ring us a second time. - Your documents covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Read the label on the pump next time, not the colour of its handle. ## About Rotten Green and where it is Rotten Green is a locality in Hampshire, situated inland at an elevation of 72 metres, and is located near the towns of Fleet and Elvetham.
