Here Is What Happens Not for a second, and not to move it: your motor stays off. Pause there. The coming few minutes decide it far more than anything else: petrol in a diesel that has not run usually amounts to clearing and flushing, right there. Here is the order of things from here, anywhere you are around Cotton. ## Petrol in a diesel, motor off — the first minute Before anything else, these — in this sequence. - Priming the fuel system pulls petrol from the tank towards the parts it damages, and turning your ignition on can be all it takes to do that. So your keys come out, and the ignition remains off completely. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mixture. - Hazards on. If you are at all near moving traffic, make your car easy to see before you do anything else. - By hand, never on the motor: that's how it comes off the petrol pump. Get the forecourt attendants to help you roll, however short the miles. - Hold on to the till receipt: the grade and the rough amount are printed on it, and they are what we ask for first. Still driving when you realised? Come off the M11 at the next junction if that's where you are, under 50 miles from Cotton, and pull over somewhere safe instead of pushing on to the services. Then begin at stage one. ## Cotton fuel drain: has the engine run yet, or not? One answer is what everything after this stage depends on. Engine not run at all? - Just your tank has petrol in it so far. - Where the vehicle stands is usually where the work is done: a drain, then a flush. - Step one matters for exactly this reason: it's the best position to be in. Run at all, even for a second: - Out of that tank, through your filter, into the fuel lines: that is how far the petrol has got. - The high-pressure pump and the fuel injectors get it on a bigger run. - Miles is what makes it a larger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps the high-pressure fuel pump and the fuel injectors oiled as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. A tank of petrol, left alone, hurts nothing. As soon as it is pumped, petrol starts wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Cotton Prepare a little, and the van finds you rather than circling. - The ideal place to start is a postcode — one beginning IP14 4 — for where you have stopped. - The road or the car park. A road name helps — Broad Road, or wherever you have pulled up. - What a car park serves is the easiest way to find it, so mention the landmark — like the one outside East of England Co-op. - Make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Cotton page. - How long the nozzle was in, or the litres from the receipt — either tells us how much. - Whether it's run. And if it has, how far plus how hard. - Hire or company car? Some agreements need the owner's authorisation for the work, and sorting it before our technicians turn up is faster than afterwards. Ring 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use . ## Waiting for a fuel drain around Cotton: what to do In the wait, the damage comes from well-meant help — which is why these count. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before your car. - Nobody — however helpful — starts it, whether to see if it runs or to shift your car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it takes that petrol back out. - 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. - Keep your ignition off — your windows and your radio included. ## Van arrived? Your fuel drain, one stage at a time - Fuel, volume, whether it's run: those replies set the job, and that's why you get a price after them rather than before. - Out of that tank comes the polluted blend: that tank is drained. - If it ran, the lines are holding petrol that has moved beyond that tank — so they are flushed. - The fuel filter is dealt with. Cleared, or swapped where the vehicle has a usable one. - Your system is primed with clean diesel. - First start on fresh diesel. Once priming is complete, your engine is started and we check that it runs correctly. Till it runs on clean diesel, our technicians stay with it. Your car returns to normal driving straight away, and long-term damage is very unusual if it has been noticed soon. ## Back on the road around Cotton after your fuel drain - Drive normally. There is nothing special to do after it's been started on fresh fuel. - Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - The work may come up later with a hire firm, an insurer or a fleet manager. Keep your paperwork. - Read the label on the petrol pump next time, not the colour of its handle. ## About Cotton, briefly Cotton is a small village in Suffolk, situated inland at an elevation of 62 metres, with a mix of detached homes and rural landscapes.
