Do not fire up the motor. If the fuel is still sitting in your tank and the engine has not run, a drain is almost always all it requires — and that gets settled in the next few minutes, not by how much got in. Petrol in Diesel drains and cleans wrongly fuelled cars where they are, throughout Ramsgreave and the rest of Lancashire, on the forecourt, at the roadside or on a drive. Contact us before everything else starts, so you will learn what comes next. ## Petrol in a diesel: what to do now - Never crank it — and don't believe it when it starts. That is the bit drivers have wrong about petrol in a diesel especially. A petrol motor given diesel typically just cannot run, and so the motorist stops and the harm halts with them. A diesel filled with petrol normally starts, idles and drives away without complaint for several miles. It is not okay. It is eating into that fuel system whenever you drive. - Switching the ignition on often primes that system, and priming is what pulls petrol out of the tank then into your pump and injectors. Those are the parts diesel keeps protected on its way through, before it ignites. Petrol manages the burning and none of the protecting. Leave the ignition alone. - That guidance presumes a diesel fuel system accepts petrol by percentage. It does not. Put diesel on top and nothing at all is cleared; what you end with is a larger tank of the same mix. And no, the octane makes no difference — super unleaded is still petrol. - Wait where you are if you sensibly can. A motor that hasn't shifted is the quickest one to sort, and we'd sooner get to a difficult place than have it started. If you're stopped on the verge on Isle of Man, turn the hazards on then leave the vehicle there. - Check where you are before calling. A postcode starting BB1 9, and the name of whatever is nearest to you. Otherwise our van circles rather than arriving. - Three answers settle the entire job: the fuel you poured in, the ballpark amount of it, and if anything has been running since. Our number is 0333 366 0103. Quarter past eight. A hurried refuel on the trip in. At about eleven it hits you, and by then the diesel Volkswagen Passat has waited at Ramsgreave & Wilpshire for three hours. Phone and keep it where it sits. What is key is the run in, because diesel both combusts and — before that — protects the pump and the fuel injectors, whereas petrol only ever ignites. Those few miles ran the pump on a fuel robbed of a lot of its protection, and no amount of standing in a car park puts any of it back. Hence the thing we ask about distance instead of hours standing, and hence the request to leave your keys where they are until we get there. ## Clearing petrol from the diesel on a forecourt Forecourts are where the work mostly begins, and where a big share of it closes. If you're still at the forecourt at BP, that is typically where the drain takes place — we work on station forecourts routinely, with the site's agreement. At a forecourt, it is stopped with the engine never run, and no place else manages it. Our engineers can still deal with it where it is, even away from the forecourt. In a car park, on a drive or in a lay-by, your car has been switched on and driven there, and that sucked fuel through the fuel filter then into the high-pressure fuel pump, right from the tank. None of that is a disaster, although the flush then has to go past your tank to the lines and the filter, and the few seconds between seeing your receipt and reaching for the keys are what determine that. Clear of the pump, the next customer can get through — so yes, let the staff help you wheel the car. Very much worth it. Four vehicle lengths is not worth the risk. ## Places we reach around Ramsgreave Brownhill, Roe Lee, Wilpshire, Pleckgate, Salesbury — every one of those on the runs that carry us out to Ramsgreave itself, a residential suburb. If yours isn't on the list it does not mean we don't come — there are pages for the majority of towns around Lancashire, and the ones named above are merely the immediate neighbours. Near the boundary, or anywhere a satnav gets wrong? Phone and check instead of assuming. The map is the area the page includes. Roadside, forecourt, driveway, car park: all of it is ground our technicians work on, and none of it asks the car to travel to us. Twenty to nine. Outside St Gabriel's Church of England Primary School. Late already, and the receipt in your hand shows unleaded. Switch the hazards on, leave your motor alone, then ring us. You may think three miles is nothing, in the Audi A4 or anything else — except that fuel is supplied on demand, and a run taken in a rush needs a great deal of it. ## Roadside stops across Ramsgreave Not everybody has a suitable place to pull in. A common call for us and not an unusual one: realised after setting off, ended up by the verge on Waverley Road or in a lay-by with the hazards flashing. Whether you stay by the car or step clear of it depends on whether being nearby seems wise. Every mile a diesel obliges you for on petrol pulls that mixture further into your fuel system — and oblige it usually will, which is why the engine does not get restarted to limp somewhere safer. However tricky the location, it is no trouble for us to get to it, and that's much better for your car than pressing on. You set off at the end, once our technicians have fired it up and checked it runs correctly on new diesel, with your system primed. Before that, in the car park at Rising Sun, the contaminated fuel comes out of your tank, the lines get flushed and the filter comes off where your Mercedes E-Class has a serviceable one. Everything begins with three questions when we reach your car: what was put in, how much of it, and whether it has been started since. ## Run it already? Pull over, and read this under 3 miles from Ramsgreave, the M65 is what matters here. It will frequently take you onto it, and some way along, before you notice a thing. Then it's smoke, a rough idle and power ebbing away — not a neat stop. Misfuelled diesels seldom give you one of those. The first safe exit is the one to take. Turn off there, and leave the restarting alone. It affects what we bring, and so say so when you phone: on a longer trip — anything near the under 10 miles to the closest city — assume the contamination has been through your filter, the pump and the fuel injectors. ## A little about Ramsgreave Ramsgreave is a suburban area in Lancashire, situated approximately 8.9 miles north of Preston and 185.4 miles northwest of London. Ramsgreave sits at an elevation of 173 metres, surrounded by nearby places such as Brownhill, Roe Lee, and Wilpshire. Ramsgreave is characterised by its predominantly semi-detached housing stock, reflecting the residential development of the area. Ramsgreave has a population of around 2030 residents, making it a small but established community. ## Our job in Ramsgreave, step by step - The replies shape the work, which is why our engineers ask before pricing: what went in, how much of it, and if your motor has run. - Our engineers empty that tank of the tainted fuel. - Fuel lines are flushed through and the fuel filter cleared, leaving nothing in your system that created any of this. - New diesel goes in, and then the system gets primed. - Your engine is started and tested to be sure it runs properly on clean diesel. That leaves the car ready to set off. Our technicians do everything wherever your car has come to a stop, which means it never needs to be taken to a garage, and when it has been noticed early, it is very unusual for there to be long-term damage. Emptying your Peugeot 208, changing the filter where there is a usable one, flushing the fuel lines, putting fresh fuel through the whole circuit: that's the job, and it's shaped by the worst of that resting in the lines rather than in that tank by this point. Three things help when you call from near Holy Souls — which side the filler is on, whether a van can park alongside without blocking the road, and if the engine has run since you filled up. On-street is the commonest place our technicians work, so the location itself is rarely the issue. A narrow parking bay is better than a car driven somewhere more handy. ## Ramsgreave AdBlue removal is a separate job AdBlue instead of petrol? Then the opening rule is unchanged — the engine remains off — while the fault underneath it's a distinct one altogether. Diluted diesel, and no protection left for your fuel system that depends on it. That's petrol. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get rust instead, plus deposits. Often the more significant of the two, AdBlue — and the detail lives on its own Ramsgreave page. Both are ours to handle. Knocking, a lumpy idle, white smoke, a throttle gone limp. That's a misfuelled diesel Citroen C3 telling you what's wrong. Switch off where you have stopped, close to Trinity Church or anywhere else, and don't restart the vehicle to find a better place. ## Budgeting for a petrol-in-diesel fuel drain in Ramsgreave What moves the price is set out below, since the job isn't one job and our technicians cannot honestly put a single figure on this page. - Started? Driven? Either answer matters more than anything else on this list. - Wrong fuel in, against what that tank holds — that proportion. - The sort of fluid in the tank, unleaded or AdBlue. - Where the vehicle is, and whether our van can safely get to and work on it. Tell us what the car is, how much got in, and if the engine has run. A straight answer comes back, not a range. For the vehicle at home that's going nowhere and isn't urgent, works too. ## Petrol in diesel questions from Ramsgreave motorists ## Can you do a fuel drain at a petrol station in Ramsgreave? Much of what our engineers do takes place nowhere else. So yes. Permission from the site is the condition. Given that, a forecourt like Prestonway Service Station is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you'll hear whether working there is possible. ## How much petrol in a diesel is too much? Ratio settles it instead of litres — and more than either, whether the engine has run. Five litres in an almost empty tank is a different matter from five in a full one — but either way, the thing that decides how much work is required is whether that mixture has been drawn through your fuel system. ## I put petrol in my diesel and drove the car. Now what? Somewhere sensible, then stop, then switch off and leave it off. Driving is what shifts the issue from the tank into your pump and injectors — but it is fixable far more regularly than motorists assume, and the single most useful thing you can do now is not restart it. ## My warranty — does a fuel drain void it? A manufacturer's warranty outlasts a drain then flush done to a proper standard, which is no modification at all. Running a diesel on petrol is the thing likelier to cause an argument with one, which is another reason to leave it turned off. ## Adding two-stroke oil, then driving home Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol weakened. No. The pump still has to put up with it, as your tank still has petrol in it after that. ## A main dealer for petrol in a diesel — necessary? You don't need one. Your car is drained and cleaned wherever it is, with no need to bring it to a franchised dealer. ## You, and your vehicle, still together? Leave the car turned off. Turn it off somewhere sensible then keep it off, if you have already driven it. Cold and still, a car is in the best position available — and people fear this far more than the recovery rate warrants. Emptying wrongly fuelled motors, Ramsgreave and the rest of Lancashire, wherever they are. Roadside. Forecourt. Home.
