Pause there. Cleared then cleaned, just where it sits: that is usually all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes to come far more than on anything else. Below is the order from here, wherever in Fairlop you are. ## Engine off: minute one with petrol in a diesel Work through the following first, in this sequence. - Bleeding the system pulls petrol from your tank towards the parts it harms, and turning the ignition on can be all it takes to do that. So your keys come out, and your ignition stays off altogether. - Topping up with diesel sounds like it thins the issue. It doesn't: nothing gets out, and the tank just holds more of the same. - Visibility comes first near moving traffic: put the hazard lights on, and only then think about everything else. - The attendants will usually help you push it clear of the pump. Ask, then move it by hand — never on the motor, even for a few yards. - Which fuel, and roughly how much? The receipt answers both, and that's where our first question starts. Don't bin it. Noticed on the move? Get off at the next exit if you're on the M11, under 3 miles from Fairlop, and pull over somewhere sensible — not at the services farther on. Step one starts after that. ## Each Fairlop fuel drain starts here: has your motor run? One answer is what everything after this point rests on. If your motor has not run at all: - All the petrol remains inside your tank, and just there. - The job is a simple drain and a flush, usually done where the vehicle stands. - This is the best place to be in, and the reason step one counts. Engine run, even briefly? - Petrol has been pulled out of the tank, through your filter and into the lines. - A bigger run takes it all the way to the high-pressure fuel pump and the injectors. - Miles is what turns it into a larger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps your high-pressure pump and the fuel injectors lubricated as it runs through them. Petrol offers them nothing, and that is why the line is drawn there. Petrol sitting in a tank harms nothing. Move that petrol, though, and it grinds down the very parts doing the moving. ## What to have ready when you call about petrol in a diesel from Fairlop Whether the van goes round or finds you comes down to a little planning. - Your location: a postcode starting IG6 3 works best. - Wherever you have parked, the road's name helps — whether that is The Bungalows or somewhere else — and so does the name of a car park. - What a car park serves is the easiest way to find it, so say the landmark — such as the one at Baylis Food and Wine. - Make and model of the vehicle, and the fact it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Fairlop page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The miles it did, and how heavily, if it ran at all. - Whose car it is. Some hire and company contracts want the owner to authorise the work, and that's quicker settled before our technicians get there than after. Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick as well. ## While you wait for a fuel drain around Fairlop The wait is where well-intended help does the damage. Hold to these. - Where the vehicle has stopped settles where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the car. - A helpful passer-by does not fire it up. Nor does anyone wanting to check it still works, or moving it a few yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays put regardless. - Not for the radio, not for the windows: your ignition stays off. ## The fuel drain, step by step, once our van arrives - Fuel, volume, whether it has run: the replies decide the job, and that's why you get a price after them rather than before. - That tank is cleared. The contaminated blend comes out of your tank. - Purging your lines follows, since a vehicle that ran has petrol past your tank, in the fuel lines themselves. - Cleaned, or swapped if the vehicle has a workable one: the filter is sorted next. - Bleeding your system comes after clean diesel is in. - The start-up. With new diesel in and the fuel system bled, it's fired up and checked to be sure it runs smoothly. Until it runs on clean diesel, we remain with it. When it has been spotted quickly, lasting damage is very rare, and the vehicle returns to normal driving right away. ## After your fuel drain: back on the road in Fairlop - After it has been started on fresh fuel, there is nothing special to do: drive normally. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over then call us back. - Hold on to the paperwork. A hire company, a fleet manager or an insurer may ask what was done. - The handle's colour is not the guide to go by next time — the label on the pump is. ## About Fairlop Fairlop is a small suburban area in the London Borough of Redbridge, situated on the River Roding at an elevation of around 33 metres.
