Here Is What Happens Stop, and leave your motor off — not on, and not for a moment to move it. The coming few minutes decide it more than anything else: petrol in a diesel that has not run usually comes down to emptying and purging, right there. Anywhere you are around Trimdon, here is how things run from now. ## Petrol in a diesel, motor off — the first minute First, the following — in this sequence. - Take your keys out. Even the ignition by itself can prime your fuel system, drawing petrol out of your tank to precisely the parts it harms, so leave the vehicle alone completely. - A bigger tank of the same mixture is all topping up leaves you, because it removes nothing. So no more diesel. - Hazards on. If you're anywhere close to moving traffic, make your car simple to see before you do anything else. - However short the way, starting it to shift it is the thing to avoid. At a forecourt, roll it away from the pump by hand instead, then ask the attendants to help. - The first question we will ask is which fuel went in and roughly how much — and the till receipt says both. Keep it. On the A1(M), under 3 miles from Trimdon, the next junction is the spot to leave the car; anywhere, the first safe spot to stop. Do not push on to the services. Then go back to stage one. ## Has it run yet? The fork in each Trimdon fuel drain What comes after this turns on one answer, and just one. Not run, not even briefly: - That petrol is still inside your tank and nowhere else. - Where the vehicle stands is normally where this work is done: a drain, then a flush. - Being here is as good as it gets — which is the entire point of stage one. Run at all, however briefly: - Petrol has been drawn from your tank, past your filter and into the lines. - The high-pressure fuel pump and the injectors see it too on a bigger run. - Distance is what makes it a larger job: flushed lines, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, protecting the pump and injectors as it passes through, which is why the line falls where it does. Petrol sitting in a tank harms nothing. Petrol being pumped is grinding down the components that move the car. ## What to have ready when you call about petrol in a diesel from Trimdon Whether the van circles or finds you comes down to a little planning. - The best place to start is a postcode — one beginning TS29 6 — for where you are. - A road name is a help: Dunelm Road, say, or whatever street you have stopped in. A car park works too. - Describe a car park by what it serves — the one outside Spar, for example — and it's much easier to find. - The vehicle. Make, model, plus that it is a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Trimdon page. - The quantity: your receipt's litres, or else how long you held the nozzle in. - Whether it's run. And if it has, how far plus how heavily. - Whose car it is. Some hire and company agreements want the owner to approve this work, and that is quicker settled before our technicians get there than after. Phone 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use . ## Trimdon fuel drain on its way? Whilst you wait Help, however well meant, is the thing that does the damage while you wait. So hold to these. - Wait with the vehicle if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a few yards. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of it gets that petrol back out. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank stays put all the same. - Not for your radio, not for your windows: your ignition remains off. ## Step by step: your fuel drain when our van gets there - First, three queries: which fuel got in, the volume, and has it run? Those answers set this job, and so the price follows them. - Out of your tank comes the polluted mix: the tank is emptied. - If it ran, the lines are holding petrol that has moved beyond the tank — so they're purged. - Then the fuel filter: swapped where there's a usable one, cleared where there is not. - The fuel system is primed with fresh diesel. - Our technicians start it only after fresh diesel has gone in and bled the system, then check that it's running smoothly. Only when it's running on fresh diesel do our engineers go. When it has been noticed soon, permanent damage is very uncommon, and your car goes back to normal use at once. ## Back on the road around Trimdon after your fuel drain - Started on new diesel, it asks nothing special of you. Just drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to your documents. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Trimdon, for a moment Trimdon is a village in County Durham, situated on the banks of a river in the north east of England.
