Stop; leave the vehicle off. Petrol in a diesel that hasn't been run is usually a simple drain and a flush, done where the vehicle stands, and what you do in the coming few minutes decides that more than anything else. Below is the sequence from this point, anywhere around Folkestone you happen to be. ## Petrol in a diesel, motor off — the first minute First, these — following this sequence. - Take the keys out. Even your ignition on its own can prime the fuel system, drawing petrol out of the tank to exactly the components it damages, so keep it off entirely. - A bigger tank of the same mix is all adding diesel gives you, since it removes nothing. So no extra diesel. - Get your car easy to see before anything else — hazards on — if there's moving traffic anywhere near you. - However short the distance, starting it to shift it is the thing to avoid. At a forecourt, roll the vehicle clear of the petrol pump by hand instead, and ask the staff to lend a hand. - Hold on to your receipt. It shows which fuel was put in plus roughly how much, which is the first thing we will ask. If you were still driving when you noticed, pull over somewhere sensible instead of pushing on for the services — on the M20, under 3 miles from Folkestone, that means the next exit. Step one follows. ## Every Folkestone fuel drain starts here: has your motor run? From this point on, everything comes down to a single answer. Not run, not even once: - The petrol is still in the tank and nowhere else. - The work is a simple drain and a flush, usually done where the car is. - No spot is better, and it's why the first stage matters so much. Run at all, however briefly: - Some petrol has left the tank already, passed through the fuel filter, and reached the fuel lines. - Your high-pressure pump as well as your injectors see it too on a bigger run. - Lines flushed, the filter sorted, and sometimes more: this job expands as the distance does. Petrol doesn't lubricate. Diesel does, oiling your high-pressure pump and injectors as it passes through, which is why the line falls where it does. Nothing is harmed by petrol that's only waiting in a tank. Pump that petrol, though, and it wears the very parts that move it. ## What to have prepared when you call about petrol in a diesel from Folkestone Whether the van goes round or finds you comes down to a little planning. - The best start is a postcode — one starting CT20 1 — for where you are. - Wherever you have parked, the road's name helps — whether that is Shellons Street or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is easier to find by what it serves, such as the one outside Lidl. - The car. Make, model, and that it's a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Folkestone page. - How long the nozzle was in, or the litres from your receipt — whichever tells us how much. - Whether it has run. And if it has, how far plus how heavily. - Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that is easier settled before we get there than after. Phone 0333 366 0103 then. Email is fine too if it can wait, with your car left at home, going nowhere. ## Folkestone fuel drain on its way? While you wait During the wait, the harm comes from well-meant help — which is why these matter. - Safety before your car. If it has stopped somewhere unsafe, get yourself away from the traffic and wait away from it. If it's safe where it stands, wait with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank remains where it is regardless. - Leave the ignition off — the windows and your radio included. ## When our van gets there: your fuel drain, step by step - Three questions. What was put in, how much, and whether it's run. The replies shape the job, which is why our price comes after them but not before. - Your tank is emptied. The polluted blend comes out of that tank. - If it ran, the lines are holding petrol that has shifted beyond your tank — so they are flushed. - Then the filter: swapped where there is a usable one, cleared where there is not. - The fuel system is primed with clean diesel. - We start the engine only after new diesel has gone in and primed the system, then confirm that it is running smoothly. Only when it is running on fresh diesel do our technicians go. If it has been noticed quickly, permanent damage is very uncommon, and your car returns to normal use at once. ## After the fuel drain is done: driving around Folkestone a second time - Started on new diesel, it asks nothing special of you. Just drive normally. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then ring us back. - The work may matter later with a hire company, an insurer or a fleet manager. Keep the paperwork. - Next time, go by the petrol pump's label rather than the colour of its handle. ## About Folkestone itself Folkestone is a town situated on the coast of Kent, overlooking the English Channel.
