Here Is What Happens Pause, and leave your motor off — not on, and not for a moment to move it. The next few minutes settle it far more than anything else: petrol in a diesel that has not run generally amounts to clearing and cleaning, right there. Here's the order of things from here, wherever you are around Cotteylands. ## Petrol in a diesel, engine off — the first minute Do the following first, in this order. - Keys out of the ignition. Turning your ignition on can be enough to prime the fuel system, while priming draws petrol out of your tank towards the parts it damages. Leave the car off altogether. - A bigger tank of the same mixture is all topping up leaves you, because it takes out nothing. So no extra diesel. - Hazards on. If you are at all close to moving traffic, make the car easy to see before you do anything else. - Off the pump by hand. On a forecourt, get the attendants to help you roll the car away from the pump. Don't start the vehicle to move it, however short the way. - Keep your receipt: the fuel and the rough amount are written on it, and they're what our technicians ask for first. If you were still driving when you realised, pull over somewhere sensible rather than pushing on for the services — on the M5, under 10 miles from Cotteylands, that means the next junction. Stage one comes next. ## Has it run yet? The fork in each Cotteylands fuel drain Everything after this point rests on one answer. Not run, not even once: - All the petrol sits inside the tank, and only there. - The work is a drain and a flush, usually done where your car stands. - This is the best place to be in, and the reason stage one matters. If it's been started, even for a moment: - Petrol has been pulled from your tank, through the filter and into the fuel lines. - Run it further and that petrol reaches the injectors, having gone through the fuel pump first. - The job expands with the mileage — lines purged, filter dealt with, sometimes more. That line falls there since diesel protects your high-pressure pump and the injectors on its way through them — and petrol doesn't. Petrol sitting in a tank damages nothing. Pump that petrol, though, and it wears the very parts that move it. ## Before you call about petrol in a diesel around Cotteylands: what our engineers need Get ready a little, and the technician finds you instead of circling. - The best start is a postcode — one starting EX16 5 — for where you are. - Wherever you have parked, the road's name is useful — whether that's Higher Cotteylands or somewhere else — and so does the name of a car park. - Car parks are found more easily by what they serve: tell us the one at Morrisons, and it is easy. - The car. Make, model, and that it is a diesel. - Which was put in matters: AdBlue is a separate job from petrol, plus Cotteylands has a page for it. So tell us. - How long the nozzle was in, or the litres from your receipt — whichever gives us how much. - The miles it covered, and how hard, if it has run at all. - Settle who owns the vehicle before we get there: some hire and company contracts want the owner to approve this work, and doing it quicker first. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## The wait for a Cotteylands fuel drain, and what to do in it Stick to these: well-meant help causes the damage during the wait. - Your safety comes before the car. Somewhere dangerous? Get away from the traffic and wait away from it. Safe where it stands? Wait with it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - A DIY drain misses the fuel already gone beyond the tank, and siphoning petrol by the road is dangerous too. - Even your radio or your windows aren't worth turning your ignition on for. ## Van arrived? The fuel drain, one stage at a time - Three questions. What got in, how much, and if it's run. The replies shape the job, which is why our price comes after them but not before. - Then your tank is drained, so the contaminated fuel is taken out. - The fuel lines are flushed. If it ran, the petrol has shifted beyond that tank, and your lines are holding it. - Your filter is seen to. Cleared, or swapped where your car has a serviceable one. - Priming follows once clean diesel is in. - The start-up. With clean diesel in and the system primed, it's started and tested to make sure it runs properly. We stay until it is running on clean diesel. It is very rare for a car caught soon to be left with long-term damage, and normal driving resumes straight away. ## Back on the road in Cotteylands after the fuel drain - After it's been started on clean fuel, there is nothing special to do: drive normally. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and call us back. - Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, go by the pump's label instead of the colour of its handle. ## About Cotteylands and where it is Cotteylands is a locality situated in a riverside setting in Devon, with an elevation of 83 metres above sea level.
