A drain and nothing else is nearly always what a vehicle requires while the fuel is still in the tank and the engine has not run, which is why it's the coming few minutes that count, not how much got in. Petrol in Diesel travels to the car wherever it has come to rest in Leckhampton or the remainder of Gloucestershire, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. Ring us before all else starts, and you'll know what follows after that. ## What to try next about petrol in a diesel - Never fire it up. Turned on regardless? Then do not believe it. Diesel in a petrol motor usually cannot run, and so the person stops and the harm ends with them. Petrol in a diesel? It starts. It ticks over. It pulls away happily, for a couple of miles. Motorists get that backwards. It is not fine — that fuel system is wearing down every mile you do. - Leave the car's ignition off too. Diesel has two roles: it burns, and before it ignites it protects your injection pump and those injectors. Petrol does the first and not the second. Turning the car's ignition on is usually all it takes to prime the system, which pulls that petrol out of your tank and into just those components. - Don't put diesel on top to water down it. A diesel fuel system does not tolerate petrol by percentage in the way that advice suggests, and topping up removes nothing — it just leaves you a larger tank of the same mix. The type makes no difference either: super unleaded is simply petrol. - Stay where you are if you sensibly can. A vehicle that has never moved is the simplest one to sort, and our team would sooner drive to an awkward location than have it started. If you are parked on the verge on Charnwood Road, turn the hazards on and keep the car there. - Have your location ready before you dial. A postcode starting GL53 0 and whatever is next to you with a name on it is the difference between the van arriving and a van circling. - Three answers decide your whole visit: the fuel you put in, the rough measure of it, plus whether anything has been going since. The line is 0333 366 0103. Quarter past eight, a quick fill on the trip in, and it dawns on you at about eleven — by then your diesel Volkswagen Passat has been left at Cheltenham Spa for three hours. Phone then keep the vehicle precisely where it stands. The drive in is the bit that is key most, since diesel performs two roles on its way through the engine: it burns, and before it burns it lubricates its high-pressure pump and those injectors. Petrol does the first and not the second. So those few miles were done with the pump labouring on a liquid that had given up most of the protection it is built around — which is why the thing our engineers ask is how many miles you went, not how long the car has been stood. ## At a forecourt: draining petrol from a diesel A big portion of the job is finished at the pump, as that is where it usually begins. The drain typically takes place there and then. Still on the forecourt at Texaco? Given the owner's agreement, that's somewhere our engineers work, and routinely. Nowhere else but the forecourt can it be spotted with the motor still cold. Anywhere else — a car park, a private drive, a lay-by — the vehicle was started and driven to get there, which means fuel was pulled from your tank, through the fuel filter and into the high-pressure fuel pump. That's not a calamity, and our technicians can still put it right where it stands. It does mean the fuel lines and your filter need flushing as well as your tank, and that is determined by the few seconds between seeing your receipt and reaching for the key. Attendants will normally help out pushing it clear of the petrol pump, which lets the next motorist get past. Accept the offer. Moving it four spaces does not justify cranking the engine. Car parks like the one outside Co-op Food are a place we visit all the time, and the fuel is rarely the difficult part. That bay is: motors either side, a trolley shelter behind, occasionally a height bar on the way in that settles whether our van can get to you at all. So tell us how hemmed in you are when you phone, and which way the car is pointing. Where we can't work alongside your diesel Skoda Octavia we'll roll the car without running it — and that isn't pedantry about a couple of seconds of running. Each start primes that fuel system and pulls more of that mix out of that tank and towards your pump, and so a vehicle shunted twice into a better bay has gradually turned into a harder job than one left precisely where it stopped. ## Leckhampton and the towns beside it Leckhampton is a residential suburb, and so we get out to the town and to the places near it on the usual trips: Pilley, Naunton Park, The Park, Charlton Park and Sandy Lane. If yours is not on the list that does not mean we don't come — there are dedicated pages for most towns in Gloucestershire, and the ones named above are just the nearest neighbours. Guessing is the habit to avoid, above all on a boundary or somewhere a satnav fails. Phone to ask. The area this page covers is on this map. Your car does not need to travel to us. Our technicians work throughout the lot — kerbside, forecourts, driveways, car parks. ## Kerbside call-outs across Leckhampton Not everyone has a decent spot to pull over. A normal call for us and not a rare one: noticed after setting off, landed along the verge on Duckworth Close or in a lay-by with the hazards flashing. Okay right there? Stay beside it. Not okay? Step out and away from it. Never restart it to reach a nicer location. It will go — a diesel on petrol normally obliges — and each mile of obliging draws that mix deeper into the fuel system. However difficult the spot, it is no problem for us to come to it, and that is a lot better for your car than driving on. ## A couple of miles on petrol in a diesel: what next? Here is where your M5 counts, under 5 miles from Leckhampton. A misfilled diesel will frequently take you onto it and some distance along before anything feels wrong, while the signs when they appear are usually a loss of power, a lumpy idle and some smoke rather than a neat stop. Take the first exit that is sensible, stop there, and never restart the vehicle to reposition. On a longer drive — anything near the under 10 miles to the nearest city — take it the mixture has been through the fuel filter, the pump and your injectors, and say so when you ring. It affects what our engineers bring. A diesel injection system works hydraulically as well as chemically: the fuel has to hold pressure, not merely burn. Thin that fuel and pressure which should build then stay built bleeds past clearances instead, leaving the motor a weaker, later, less even delivery than it was designed about. Petrol thins diesel, and diesel has to be heavy enough to seal the close-fitting components it passes through — that's the entire mechanism. It explains the ordinary Burrow's Field call too: a diesel Audi A4 that drove out without a murmur and came back down on power, lumpy at idle, maybe smoking a little. None of which is the motor failing, and that is the bit worth hearing. The fuel has stopped behaving like diesel. Put the fuel right and it stops. ## Where is Leckhampton? Leckhampton is a suburban area in Gloucestershire, situated near the River Churn and approximately 7 miles south of Gloucester. Leckhampton sits at an elevation of around 86 metres, with semi-detached housing being the predominant type of accommodation. Leckhampton is close to nearby places such as Pilley and Naunton Park, and is located within the wider Gloucester urban area. Leckhampton has a population of around 5183 residents. ## What follows when we arrive with you around Leckhampton - Three things get checked before any price — your fuel that went in, the quantity, and if anything has been run since. Each answer shapes the work. - The polluted fuel comes out of that tank. - Lines rinsed, filter cleared. Whatever is left after that isn't the thing that caused the issue. - The system gets bled, on fresh diesel. - It is run with fresh diesel in it, and our engineers check that it is running smoothly. Then it's ready to set off. Our technicians do all of it wherever the vehicle has ended up, which means it never has to be taken to a garage, and if it has been spotted quickly, it's very rare for there to be long-term damage. Rarely the problem, the place. On-street is the commonest place we work, and a narrow parking space is far preferable to a motor that has been driven somewhere more convenient. What does help, when you ring from near Malvern Inn, is three things: the side the filler is on, whether a van can pull up next to without blocking the road, and whether anything has run since you filled up. Then the Ford Focus gets cleared, your filter changed where a usable one exists, the lines cleaned and fresh fuel put through the entire system — since by now the worst of it is in the lines, not your tank. ## AdBlue in the diesel tank instead, in Leckhampton? Never start it: that first instruction holds whether what was put in was AdBlue or petrol. What changes is this issue itself. Thinned diesel, and no lubrication left for your fuel system that relies on it. That's petrol. AdBlue is urea in water, and in a diesel tank it causes corrosion and build-up instead. Both are ours. There is a separate Leckhampton page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two. ## How much is a petrol-in-diesel drain in Leckhampton? One number would not be fair here, since this is not one job. These are the things that move it: - This is the key one: whether the engine has been run, or driven. - The tank's capacity, set against how much of the wrong fuel went into it. - The kind of liquid in the tank, petrol or AdBlue. - Where the car is, and whether a van can safely get to and work on it. A clear answer instead of a range is what you get for telling us three things: your car, the quantity, and if it has run. If it is not urgent — the vehicle is at home and going nowhere — is fine too. Someone certain will tell you to drain the vehicle then put fresh diesel in. Half right, that. Try it on a diesel Dacia Duster close to Gas Lamp Base and the engine will start — which is exactly why it sounds like sense. Here is the trouble: there's petrol left in the filter and the feed lines, and the first thing the motor does is draw it back through the pump a second time. Draining a tank achieves nothing about fuel that already left the tank. Phone us. The system gets cleaned, your filter comes off where there's one worth removing, and that's what separates a fixed vehicle from one that simply starts. ## Petrol in diesel queries from Leckhampton drivers ## I am on a forecourt in Leckhampton. Can you drain it on the spot? A big part of this work takes place there, so yes. Regularly, provided the site agrees: Morrisons, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that place is something we answer straight away. ## A few litres of petrol in a diesel — too much? Litres aren't the yardstick. Proportion is, and much more than either, it matters whether anything has been run. Five litres in a nearly empty tank is a separate case from five in a full one — but either way, the thing that decides how much work is needed is if that mix has been pulled through the system. ## Petrol in my diesel, and I have driven it Stop somewhere sensible, switch off, and leave the vehicle off. Not restarting it is the single most helpful thing available to you now. Driving does move the trouble out of your tank then into the pump and injectors, yes, and it stays fixable far more often than drivers assume. ## Is a fuel drain going to void my warranty? A manufacturer's warranty withstands a drain and flush done to a correct standard, which is no modification at all. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the car switched off. ## Could I put some two-stroke in and just drive? No. Two-stroke oil is an old remedy for a distinct fault and it does not replace what petrol has weakened. The pump still has to cope with it, because your tank still has petrol in it later. ## Do I need a main dealer for petrol in a diesel? Wherever your car is, we drain and clean it there, so a drive to the main dealer does not come into it. ## Waiting next to it? Shut off is the way the car remains. Already driven it? Then pull in somewhere safe, switch off, and let the car remain that way. This is recoverable from far more commonly than motorists expect, and a parked, cold motor is the best position to be in. Throughout Gloucestershire and in Leckhampton: on-site fuel draining, at home or on the forecourt or at the kerbside.
