The coming few minutes decide it far more than anything else: petrol in a diesel that has not run generally amounts to draining and flushing, right there. Wherever you are in Hamwell Leaze, this is how things run from now. ## Petrol in a diesel? What to do in minute one In this sequence, and before anything else: - The ignition off, keys out. Switched on, the ignition can prime your system — and priming is what draws petrol out of your tank into the parts it harms. - No diesel on top. More fuel in removes none of that petrol — it just makes you with extra of the same blend. - Hazard lights on. If you are anywhere close to moving traffic, make your car simple to see before you do anything else. - Off the petrol pump by hand. On a forecourt, ask the staff to help you roll the vehicle clear of the petrol pump. Do not crank it to move it, however short the way. - The first thing we will ask is which fuel went in and about how much — and the till receipt shows both. Keep it. Still on the move when you noticed? Come off the M5 at the next exit if that is where you are, under 5 miles from Hamwell Leaze, and stop somewhere sensible rather than pushing on to the services. Then start at step one. ## Has it run yet? The fork in each Hamwell Leaze fuel drain From this stage on, everything hinges on a single answer. If your engine has not run at all: - Only your tank has petrol in it for now. - Where the car stands is normally where this work happens: a drain, then a flush. - Stage one matters for exactly this reason: it's the best place to be in. If it's been started, even for a moment: - Petrol has been pulled out of your tank, through the filter then into the fuel lines. - Run it further and the petrol gets to the fuel injectors, having gone through the pump first. - Flushing the lines, the fuel filter dealt with, and sometimes more: this job grows as the distance does. Why the line falls there: diesel lubricates the high-pressure fuel pump as well as the injectors as it flows through them, and petrol does not. Nothing is damaged by petrol that's only resting in a tank. Pump the petrol, though, and it wears the very parts that move it. ## Hamwell Leaze, petrol in a diesel: have these prepared before you call Whether the van circles or finds you comes down to a little preparation. - GL5 4 plus the remainder of the postcode is the best way to begin telling us where you are. - The street or the car park. A road name helps — Hunters Way, or wherever you have stopped. - Car parks are found most easily by what they serve: tell us the one at The Co-operative Food, and it is simple. - Tell us what your vehicle is — make, model — and check it's diesel. - Say which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Hamwell Leaze. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - The miles it covered, and how heavily, if it ran at all. - Whose motor it is. Some hire and company agreements want the owner to authorise the work, and that is quicker settled before our engineers turn up than after. Then ring 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick too. ## While you wait for a fuel drain in Hamwell Leaze Stick to these: well-meant help does the damage during the wait. - Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it is 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 favour: nobody starts it. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of that takes the petrol back out. - No home-made clearing. Siphoning petrol into a can by the kerbside is hazardous, and it leaves your fuel that has by now gone beyond the tank. - Leave your ignition off — the windows and your radio included. ## When our van gets there: your fuel drain, step by step - Three queries. What got in, how much, and whether it's run. Those answers decide this job, which is why the quote comes after them and not before. - Out of that tank comes the polluted blend: the tank is emptied. - If it ran, the fuel lines are carrying petrol that has shifted beyond your tank — so they are cleaned. - Where the vehicle has a workable filter, it's swapped; otherwise, cleared. - Fresh diesel in, and the fuel system primed. - Starting it. Once the fuel system is bled with new diesel, our engineers start the engine and confirm it runs correctly. The vehicle has new diesel running through it before we leave. It is very uncommon for a vehicle spotted soon to be left with lasting damage, and normal use starts again right away. ## After your fuel drain: back on the road in Hamwell Leaze - Drive normally. There's nothing unusual to do after it has been started on clean fuel. - Pull over and call us back if anything seems wrong early on — a light on the dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - Your paperwork answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Check the label on the pump next time, not the colour of the handle. ## About Hamwell Leaze Hamwell Leaze is a suburban area situated on the riverside in Gloucestershire, with a mix of semi-detached housing and other residential properties.
