Motor off. Keep the vehicle that way — no moment on, no moving it anywhere. The coming few minutes decide it more than anything else: petrol in a diesel still unrun normally amounts to clearing then rinsing, on the spot. Here is the sequence of things from now, wherever you are around St Osyth. ## Petrol in a diesel, engine off — the first minute Work through the following in order, first. - Ignition off, keys out. Turned on, the ignition can prime the system — and priming is what draws petrol out of the tank into the components it harms. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Make your car easy to see before anything else — hazard lights on — if there's moving traffic anywhere near you. - The attendants will generally help you roll it away from the petrol pump. Ask, and move it by hand — never on your engine, even for a couple of yards. - The first thing you will be asked is which fuel went in and roughly how much — and the till receipt says both. Hold on to it. If you were still driving when you noticed, pull over somewhere sensible instead of pushing on for the services — on the M2, under 50 miles from St Osyth, that means the next junction. Step one follows. ## Every St Osyth fuel drain starts here: has your motor run? What comes after this rests on one answer, and only one. If the motor has not run at all: - Nowhere but that tank: that's where that petrol yet is. - Usually it's emptied and rinsed just where the vehicle is. - This is the best spot to be in, and the whole reason stage one counts. Motor run, however briefly? - The fuel lines and the filter now carry petrol drawn from that tank. - The high-pressure fuel pump and your injectors get it on a longer run. - The job grows with the miles — lines rinsed, filter dealt with, occasionally more. Why the line falls there: diesel protects the high-pressure pump as well as your injectors as it flows through them, and petrol does not. Nothing is harmed by petrol that's only sitting in a tank. As soon as it is pumped, petrol begins wearing whatever moves it. ## Before you call about petrol in a diesel in St Osyth: what our technicians need A technician that circles versus a technician that finds you: a little planning is the difference. - The ideal place to start is a postcode — one beginning CO16 8 — for where you have stopped. - Give the street — The Bury or wherever you have stopped — or the car park. - What a car park serves is the quickest way to find it, so say the landmark — such as the one outside Tesco Express. - The car. Make, model, and that it's a diesel. - Say which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for St Osyth. - The quantity: the receipt's litres, or else how long you had the nozzle in. - The mileage it did, and how hard, if it has run at all. - Whose vehicle it is. Some hire or company agreements want the owner to authorise the work, and that's easier settled before our engineers turn up than after. Phone 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use . ## The wait for a St Osyth fuel drain, and what to do in it Hold to these: kindly meant help causes the damage during the wait. - Where the vehicle has stopped settles where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of your car. - No one — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way. - Additives remain in your boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - A home-made drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is risky besides. - Keep the ignition off — your windows and the radio too. ## Step by step: the fuel drain when the van arrives - The quote comes after three queries, not before them — what went in, how much, and if it has run — because those replies shape the job. - Then the tank is emptied, so the tainted fuel comes out. - Petrol that has shifted beyond that tank travels in your lines once it ran, and your lines are flushed to clear it. - Cleaned, or replaced if your car has a serviceable one: your filter is sorted next. - Bleeding the system follows after clean diesel is in. - Starting the car. After the system is primed with clean diesel, our engineers fire it up and make sure it runs correctly. The vehicle has clean diesel running through it before our engineers head off. Permanent damage is very unusual when it has been caught soon, so the vehicle can go right back to normal use. ## St Osyth, after your fuel drain: back on the road - After it's been started on clean fuel, there's nothing special to do: drive normally. - Pull over and call us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - Hold on to the documents. A hire firm, a fleet manager or an insurer may ask what was done. - The handle's colour isn't the thing to go by next time — the label on the pump is. ## About St Osyth St Osyth is a coastal village in Essex, situated near the mouth of the Colne estuary at an elevation of around 20 metres.
