Motor off. Keep it that way — no moment on, no shifting it at all. The coming few minutes settle it more than anything else: petrol in a diesel still unrun usually amounts to draining then flushing, right there. What follows is the sequence from here, anywhere around Frogs Green you are. ## Motor off: minute one with petrol in a diesel In this order, all before anything else: - Keys out of your ignition. Turning your ignition on can be all it takes to prime the system, while priming draws petrol out of your tank towards the components it harms. Leave the car off completely. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture. - Get your car simple to see before anything else — hazards on — if there's traffic going past anywhere close to you. - By hand, not on your engine: that's how it comes off the pump. Ask the forecourt staff to help you roll, however short the miles. - The first thing you will be asked is which fuel went in and roughly how much — and your receipt says both. Keep it. On the M11, under 5 miles from Frogs Green, the next junction is the location to leave the vehicle; anywhere, the first safe location to stop. Don't press on to the services. Then go back to step one. ## Frogs Green fuel drain: has your engine run yet, or not? From this point on, everything hinges on a single answer. If your motor has not run at all: - Only your tank has petrol in it for now. - Where the vehicle stands is usually where this work happens: a drain, then a flush. - This is the best case — which is the entire point of step one. If it's been started, even for a second: - Some petrol has left that tank already, passed through your filter, and reached your lines. - On a bigger run it has got to your high-pressure pump and your injectors. - The job expands with the miles — lines cleaned, filter sorted, sometimes more. Diesel keeps the high-pressure fuel pump and the injectors lubricated as it goes through them. Petrol offers them nothing, and that is why the line is drawn there. In the tank, left alone, petrol does no harm. Petrol being pumped is wearing the components that shift it. ## Frogs Green, petrol in a diesel: have these ready before you call A little planning is the difference between a technician that finds you and a technician that circles. - Where you have stopped. A postcode starting CB10 2 is the best start. - A road name is a help: Radwinter Road, say, or whichever street you have stopped in. A car park does the trick too. - Describe a car park by what it serves — the one outside Aldi, for example — and it's much quicker to find. - The car. Make, model, and that it is a diesel. - Which was put in counts: AdBlue is a separate job from petrol, plus Frogs Green has a page for it. So say. - How long the nozzle was in, or the litres on the receipt — whichever tells us how much. - Whether it's run. Then if it has, how far and how hard. - Sort who owns your car before we arrive: some hire and company contracts want the owner to approve this work, and doing it quicker first. Ring 0333 366 0103 then. Writing to works too if it can wait, with the vehicle left at home, going nowhere. ## The wait for a Frogs Green fuel drain, and what to do in it The wait is where kindly meant help does the harm. Stick to these. - Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic and wait away from it. Fine where it sits? Stay with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - Siphoning petrol into a can by the kerbside is dangerous — and it still leaves whatever fuel has already gone beyond that tank. Do not try a home-made drain. - Keep your ignition off — the windows and your radio included. ## Van arrived? The fuel drain, one step at a time - Our quote comes after three questions, not before them — what got in, how much, and if it has run — since the replies set the job. - The tank is emptied. The tainted mixture comes out of the tank. - Rinsing the lines comes next, because a vehicle that ran has petrol past that tank, in the fuel lines themselves. - Where the car has a workable filter, it's swapped; if not, cleared. - Your system is primed with clean diesel. - First start on clean diesel. When bleeding is done, the engine is started and we check that it runs smoothly. Only when it's running on new diesel do we go. The car returns to normal use right away, and long-term damage is very unusual when it has been caught early. ## Frogs Green, after your fuel drain: back on the road - Once it has been started on clean fuel, there is nothing unusual to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and ring us a second time. - Keep the documents. A hire company, a fleet manager or an insurer may ask what was done. - Next time, check the petrol pump. The label, not the colour of the handle. ## About Frogs Green and where it is Frogs Green is a small locality in Essex, situated inland at an elevation of around 108 metres, and is located near the villages of Wimbish and Maple End.
