Petrol in a diesel that hasn't been run is generally a drain plus a flush, done right where your vehicle sits, and what you do in the next few minutes settles that more than anything else. Here's the order of things from now, wherever you are in Parsons Heath. ## Minute one: petrol in a diesel, motor off Work through these before anything else, in this order. - Keys out of the ignition. Switching the ignition on can be all it takes to prime your fuel system, and priming pulls petrol out of your tank towards the parts it harms. Keep it off altogether. - No diesel on top. More fuel in takes away none of the petrol — it only makes you with more of the same blend. - Near moving traffic? Then the hazard lights come on before everything else, and so the car is easy to spot. - However short the way, starting it to move it is the thing to avoid. At a forecourt, roll it clear of the petrol pump by hand instead, then ask the staff to help. - Keep the till receipt. It shows which fuel was put in and about how much, which is the first thing we will ask. Still driving when you realised? Come off the M11 at the next exit if that is where you are, under 50 miles from Parsons Heath, and pull over somewhere sensible rather than pushing on to the services. Then begin at step one. ## The fork in each Parsons Heath fuel drain: has it run yet? One answer is what everything after this point rests on. If it has not once been started: - Only that tank has petrol in it so far. - Where the vehicle sits is usually where this work happens: a drain, then a flush. - This, here, is the best place to be in, and the whole reason step one counts. If your motor has run, even for a moment: - Out of that tank, past your filter, into the lines: that is how far that petrol has travelled. - On a bigger run it has got to your high-pressure pump as well as the fuel injectors. - Miles is what turns it into a bigger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps the high-pressure fuel pump and the 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, damages nothing. Move that petrol, though, and it wears the very parts doing the moving. ## Calling about petrol in a diesel from Parsons Heath: what to have prepared A little preparation is the difference between a van that finds you and a technician that circles. - The best start is a postcode — one starting CO4 0 — for where you have stopped. - A road name helps: Vale Close, say, or whatever street you have stopped in. A car park does the trick too. - Car parks are found most easily by what they serve: say the one outside Co-op Daily, and it's straightforward. - Make and model of the vehicle, and the fact it's a diesel. - Which was put in counts: AdBlue is a separate job from petrol, plus Parsons Heath has a page for it. So say. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - The distance it did, and how hard, if it ran at all. - Hire or company car? Some agreements need the owner's authorisation for this work, and getting it before our technicians turn up is faster than after. Phone 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## Parsons Heath fuel drain on its way? Whilst you wait In the wait, the harm comes from well-intended help — which is why these count. - Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic and wait away from it. If it is safe where it is, wait with it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out again. - No DIY clearing. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has by now gone beyond that tank. - Not for your radio, not for the windows: your ignition stays off. ## When our van gets there: your fuel drain, step by step - The price comes after three queries, not before them — what was put in, how much, and whether it's run — since those answers decide this job. - Emptying it is how the blend gets taken out of that tank. - Petrol that has shifted beyond your tank sits in your lines once it ran, and the fuel lines are flushed to shift it. - The filter is sorted. Cleared, or replaced where the car has a serviceable one. - The system is primed with clean diesel. - The start-up. With clean diesel in and the system primed, it is started and tested to make sure it runs properly. Our engineers wait until it is running on fresh diesel. When it has been spotted quickly, lasting damage is very uncommon, and your car goes back to normal driving right away. ## Parsons Heath, after the fuel drain: back on the road - After it has been started on fresh fuel, there's 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. - An insurer, a fleet manager or a hire firm may ask what was done, and so keep the paperwork. - Next time, read the petrol pump. The label, not the colour of the handle. ## About Parsons Heath and where it is Parsons Heath is a suburban area located near Colchester in Essex, sitting at an elevation of around 35 metres in the inland landscape of eastern England.
