Pause; leave the vehicle off. Has not been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and no other factor decides that more than the next few minutes do. From now on, step by step, wherever you are around Townsend: ## Minute one: petrol in a diesel, motor off In this sequence, and before anything else: - Priming your fuel system draws petrol from your tank towards the parts it harms, and turning the ignition on can be all it takes to do that. So the keys get taken out, and your ignition stays off completely. - A bigger tank of the same mixture is all topping up gives you, because it takes out nothing. So no extra diesel. - Visibility comes before the rest beside moving traffic: switch the hazard lights on, and only then deal with everything else. - However short the way, starting it to shift it is the mistake. At a forecourt, push it away from the pump by hand instead, and ask the attendants to help. - Keep the till receipt. It shows which fuel was put in and roughly how much, which is the first thing we'll ask. On the M5, under 3 miles from Townsend, the next exit is the place to leave it; anywhere, the first sensible spot to stop. Do not push on to the services. Then go back to step one. ## Townsend fuel drain: has the motor run yet, or not? From this stage on, everything comes down to a single answer. If it has never been started: - Just that tank has petrol in it so far. - Where the car stands is usually where the work is done: a drain, then a flush. - Step one counts for exactly this reason: it's the best place to be in. Run at all, however briefly: - Out of your tank, past your filter, into the lines: that's how far that petrol has got. - On a longer run it has reached the high-pressure fuel pump and your injectors. - The job grows with the distance — lines flushed, filter sorted, sometimes more. The line falls there since diesel protects your high-pressure pump and the injectors on its way through them — and petrol does not. A tank of petrol, left still, damages nothing. Once it's pumped, petrol begins wearing whatever moves it. ## Calling about petrol in a diesel from Townsend: what to have prepared Prepare a little, and the van finds you instead of circling. - The ideal place to start is a postcode — one beginning GL11 4 — for where you are. - The road or the car park. A road name helps — Foundry Rise, or wherever you have pulled up. - Car parks are found most easily by what they serve: tell us the one outside Sainsbury's, and it is simple. - That it's a diesel, along with the make and model of your vehicle. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Townsend page. - The quantity: the receipt's litres, or else how long you had the nozzle in. - Has it run? If so, tell us how far it got, and the way it was driven. - Settle who owns your car ahead of when our technicians turn up: some hire and company contracts want the owner to approve the work, and that is faster first. Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — does the trick too. ## Whilst you wait for a fuel drain in Townsend The wait is where well-meant help does the harm. Stick to these. - Wait with the car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one — however helpful — starts it, whether to see if it runs or to move the vehicle a short way. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - Siphoning petrol into a can by the kerbside is risky — and it also leaves whatever fuel has already gone beyond that tank. Do not drain the car yourself. - Not for the radio, not for your windows: your ignition stays 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 decide the job, so the price follows them. - That tank is drained. The contaminated mixture comes from that tank. - Rinsing the fuel lines comes next, because a vehicle that ran has petrol past the tank, inside the fuel lines themselves. - Your filter is sorted. Cleared, or swapped where your car has a serviceable one. - Fresh diesel in, and the fuel system primed. - Starting up. When the system is bled with new diesel, we fire it up and check it runs smoothly. Your car has fresh diesel running through it before our engineers leave. The car goes back to normal use straight away, and long-term damage is very uncommon if it has been spotted quickly. ## After the fuel drain: back on the road around Townsend - Drive normally. There's nothing special to do after it has been started on clean fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us again. - Keep your paperwork. A hire company, a fleet manager or an insurer may ask what was done. - Next time, go by the pump's label instead of the colour of its handle. ## About Townsend itself Townsend is a suburban area situated on the riverside in Gloucestershire, with a mix of semi-detached housing and other residential properties.
