Emptied and flushed, just where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes ahead more than on anything else. Below is the sequence from here, anywhere in Charlesville you are. ## Petrol in a diesel, engine off — the first minute Before anything else, the following — in this order. - Take the keys out. Even your ignition by itself can prime your fuel system, drawing petrol out of your tank to exactly the components it damages, and so leave the car off completely. - A bigger tank of the same mixture is all topping up gives you, since it removes nothing. So no extra diesel. - Near moving traffic? Then the hazards go on before everything else, so the vehicle is easy to see. - However short the way, starting it to shift it is the thing to avoid. On a forecourt, push the vehicle away from the petrol pump by hand instead, and ask the staff to help. - The first thing you will be asked is which fuel you put in and about how much — and the receipt shows both. Keep it. Realised on the move? Get off at the next junction if you are on the M4, under 10 miles from Charlesville, and stop somewhere safe — not at the services farther on. Step one comes after that. ## Each Charlesville fuel drain starts here: has your motor run? Everything after this point depends on one answer. Motor not run at all? - Only the tank has petrol in it for now. - The job is a drain and a flush, normally done where your car is. - Being here is as good as it gets — which is the entire point of stage one. If your motor has run, even briefly: - From the tank, through the fuel filter, into your lines: that is how far the petrol has got. - Run it farther and the petrol reaches the injectors, having gone through the pump first. - The job expands with the mileage — lines flushed, filter seen to, sometimes more. Diesel keeps your high-pressure pump and the injectors lubricated as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. Petrol resting in a tank damages nothing. Petrol being pumped is wearing the parts that shift it. ## Calling about petrol in a diesel from Charlesville: what to have ready Prepare a little, and the van finds you instead of circling. - The ideal start is a postcode — one starting NP4 8 — for where you have stopped. - A road name helps: Park View, say, or whichever street you've stopped in. A car park does the trick too. - Or the landmark. A car park is easier to find by what it serves, like the one outside Spar. - That it is a diesel, plus the make and model of the car. - Tell us which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Charlesville. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - Whether it has run. And if it has, how far and how heavily. - Whose car it is. Some hire and company agreements want the owner to approve this work, and that's easier settled before our engineers turn up than after. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works as well. ## The wait for a Charlesville fuel drain, and what to do in it Stick to these: well-meant help does the damage during the wait. - Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the vehicle. - A helpful passer-by does not fire it up. Nor does anybody wanting to check it still works, or rolling it a couple of yards. - Something from your boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Siphoning petrol into a can at the kerbside is dangerous — and it still leaves whatever fuel has already gone beyond that tank. Do not try a home-made drain. - Not for the radio, not for the windows: the ignition stays off. ## When the van arrives: your fuel drain, step by step - Fuel, volume, whether it's run: those answers set this job, and that is why we give a quote after them instead of before. - Your tank is emptied. The polluted mix comes out of your tank. - The fuel lines are flushed. If it ran, that petrol has shifted beyond your tank, and the fuel lines are carrying it. - Where the vehicle has a usable filter, it is swapped; otherwise, cleared. - Priming comes once clean diesel is in. - The first start on new diesel. Once bleeding is finished, the motor is fired up and our technicians confirm that it runs properly. Our engineers remain until it's running on clean diesel. Long-term damage is very uncommon when it has been spotted quickly, so the car can go straight back to normal use. ## Once your fuel drain is done: driving around Charlesville once more - Nothing unusual is needed after a start with fresh diesel — normal driving is all. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us a second time. - An insurer, a fleet manager or a hire company may ask what was done, and so keep the documents. - The handle's colour is not the thing to go by next time — the label on the petrol pump is. ## About Charlesville Charlesville is a suburban area in Torfaen, situated on the riverside with a mix of terraced housing.
