Stop; leave the vehicle off. The coming few minutes decide it far more than anything else: petrol in a diesel still unrun usually comes down to draining and purging, right there. Below is the order from this point, anywhere in Greenhill you are. ## Petrol in a diesel? What to do in minute one Before anything else, the following — following this sequence. - Bleeding the system pulls petrol from the tank towards the components it harms, and turning your ignition on can be enough to do that. So your keys get taken out, and the ignition stays off completely. - No diesel on top. More fuel in takes away none of that petrol — it just makes you with more of the same mixture. - Close to moving traffic? Then the hazards come on before everything else, so the vehicle is simple to spot. - Off the petrol pump by hand. At a forecourt, get the attendants to help you push the vehicle away from the petrol pump. Don't fire it up to shift it, however short the distance. - Hold on to your receipt: the fuel and the rough amount are written on it, and they are what our technicians ask about first. Still on the move when you noticed? Come off the M4 at the next junction if that's where you are, under 10 miles from Greenhill, and pull over somewhere sensible and not pushing on to the services. Then start at step one. ## Has it run yet? The fork in every Greenhill fuel drain From this point on, everything hinges on a single answer. Motor not run at all? - The petrol is still in that tank and nowhere else. - The job is a drain and a flush, normally done where the car is. - This is the best place to be in, and the reason stage one matters. Run at all, however briefly: - From the tank, through your filter, into the lines: that is how far that petrol has got. - A longer run carries it all the way to the high-pressure pump and the fuel injectors. - Miles is what turns it into a larger job: the lines flushed, a filter seen to, and at times more than that. Petrol does not lubricate. Diesel does, oiling the high-pressure pump and injectors as it flows through, which is why the line falls where it does. Nothing is damaged by petrol that is just sitting in a tank. Move the petrol, though, and it grinds down the very parts doing the moving. ## Calling about petrol in a diesel from Greenhill: what to have ready A little planning is the difference between a van that finds you and a van that goes round. - Your location: a postcode starting SN13 9 serves best. - The street or the car park. A road name helps — Shearwater Way, or wherever you have pulled up. - Car parks are found most easily by what they serve: say the one at Co-op Food, and it's easy. - Say what the vehicle is — make, model — and confirm it is diesel. - Which went in matters: AdBlue is a separate job from petrol, and Greenhill has a page just for that. So tell us. - How much. Litres from the receipt, or how long the nozzle was in the filler. - If it's run, how far and how hard — as well as if it's run at all. - Hire or company car? Some agreements need the owner's go-ahead for the work, and sorting it before our engineers arrive is quicker than afterwards. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## Greenhill fuel drain on its way? While you wait The wait is where kindly meant help does the damage. Hold to these. - Wait with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - Siphoning petrol into a can by the kerbside is dangerous — and it still leaves whatever fuel has already gone beyond that tank. Do not drain it yourself. - Not for your radio, not for your windows: the ignition remains off. ## Step by step: your fuel drain when the van arrives - Fuel, amount, whether it's run: the answers decide this job, and that is why we give a price after them rather than before. - The tank is drained. The tainted mixture comes out of that tank. - Your lines are purged. If it ran, that petrol has moved beyond the tank, and your lines are holding it. - Where the vehicle has a serviceable filter, it's replaced; otherwise, cleared. - Fresh diesel goes in, then your system is primed. - First start on clean diesel. Once bleeding is complete, your engine is started and our engineers make sure that it runs properly. Our technicians stay until it is running on fresh diesel. Long-term damage is very unusual when it has been noticed quickly, so your car can go straight back to normal driving. ## After your fuel drain is done: driving in Greenhill once more - After it's been started on fresh fuel, there is nothing special to do: drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and ring us a second time. - Hold on to your documents. A hire firm, a fleet manager or an insurer may ask what was done. - Check the label on the petrol pump next time, not the colour of its handle. ## About Greenhill, for a moment Greenhill is a suburban area in Wiltshire, situated inland at an elevation of 104 metres, approximately 7 miles from the city of Bath.
