If you have not started your engine as yet, do not. A fuel drain and nothing more is nearly always what a vehicle needs while the petrol is still in that tank and your engine has not run, which is why it's the coming few minutes that count, not how much was put in. Petrol in Diesel travels to your car wherever it has stopped in Barbers Moor or the remainder of Lancashire, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. Contact us before everything else happens, and you will hear what follows after that. ## The first five minutes: petrol in a diesel - Give a petrol motor diesel and it will normally fail to run at all, and so the driver stops there and so does the wear. Feed a diesel petrol and the car starts, it ticks over, it pulls away — fine for a couple of miles. Motorists have that reversed, which is the thing they get wrong about petrol in a diesel in particular. So never crank it. And once started, do not rely on it: the fuel system is grinding whenever you drive. - Diesel ignites, and before it combusts it lubricates — that high-pressure pump, its injectors. Petrol handles only the burning. So leave the ignition alone as well: turning it on is usually all it takes to prime that system, and priming pulls petrol from your tank into exactly those components. - That guidance supposes a diesel fuel system copes with petrol by percentage. It will not. Put diesel on top and nothing at all is taken out; what you have is a larger tank of the same mixture. And no, the octane makes no difference — super unleaded is just petrol. - Stay put if it is safe to. Hazards on, motor off, keep the vehicle. Wherever you have stopped — the verge on Ridley Lane, anywhere — an awkward location for us trumps a started engine, and nothing is easier for us to deal with than a car that never moved. - Before you call, get your position. Anything closest to you with a sign on it, plus a postcode starting PR26 9 — that's what settles whether our van arrives or circles. - What went in, roughly how many litres, and also if the engine has started — these three details shape the full visit. Call 0333 366 0103 and tell us. Quarter past eight. A quick fill on the road in. Somewhere around eleven it dawns on you, and by then the diesel Volkswagen Golf has waited at Croston for three hours. Phone us and keep the car where it stands. What is key is the drive in, because diesel both ignites and — before that — protects your pump and your injectors, while petrol only ever combusts. Those couple of miles ran your pump on a fluid robbed of much of its protection, and no quantity of standing in a car park gives any of that back. Hence the question about mileage instead of hours sitting, and hence the request to leave the keys be till our engineers turn up. ## Clearing petrol from the diesel at a forecourt The job starts at a pump, usually. Frequently the work ends at one as well. Our technicians work on garage forecourts routinely, with the station's consent, and so if you're still at Texaco that is normally where the drain happens. No place other than a garage can the mistake be spotted with the motor still unstarted. Fuel drawn out of your tank and through the filter, all the way to the high-pressure fuel pump, is what occurs when the motor is started and your car is driven to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and the fuel lines together with that tank. That's still not a catastrophe, and our technicians sort it out where your car stands. What settles it is whether the key was turned in the seconds after the receipt was read. Clear of the petrol pump, the next motorist can get by — so yes, let the attendants help you push it. Worth it. Firing the car over four vehicle lengths? Don't. ## Will we reach your corner of Barbers Moor? Croston, Wymott, Newtown, Bretherton, Ulnes Walton — each of those on the rounds that take us out to Barbers Moor as well, a small village. There are dedicated pages for the majority of towns across Lancashire, and the ones listed above are merely the immediate neighbours — so yours being absent from that list means nothing about if we come. On the border, or anywhere a satnav gets wrong? Call us and enquire instead of assuming. The patch the page covers appears on our map. The vehicle never needs to come to us. Our technicians work across all of it — kerbside, forecourts, driveways, car parks. ## Stuck on the roadside in Barbers Moor The chance to stop anywhere sensible doesn't come to everyone. If you noticed after setting off and ended up on the verge of Moor Road, or at a lay-by somewhere with the hazard lights on, that's a routine call for us and not a rare one. Whether you wait by the car or step clear of it depends on if staying in it seems safe. Do not restart the engine to limp the vehicle somewhere handier — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mix further into the fuel system. However difficult the place, it's no trouble for us to get to it, and that is a lot better for the vehicle than carrying on. The components that should be getting protected are wearing down instead, and the car gives no sign of it: a diesel on a weakened tank starts and pulls away perfectly well. Risk the journey home from Lord Nelson? Not a chance. Ring us then leave the Audi A4 where it stands. ## So you've run it? Petrol in a diesel after some miles Your M6 is the road that counts here, and it lies under 5 miles from Barbers Moor. It will often take you onto it, and some way along, before you feel a thing. Then it's some smoke, an uneven idle and power ebbing away — not a clean stop. Misfilled diesels rarely give you one of those. The first safe exit is the one to take. Turn off there, then leave the restarting alone. It changes what we bring, and so mention it when you phone: on a longer trip — anything close to the under 10 miles to the closest city — take it the mixture has been through the filter, your pump and your injectors. ## Barbers Moor itself Barbers Moor is a locality situated on the riverside in Lancashire, with an elevation of around 10 metres. Barbers Moor lies near the cities of Preston and the surrounding villages of Croston and Wymott. Barbers Moor has a mix of housing types, but terraced housing is predominant in the area. Barbers Moor is located approximately 6.9 miles from Preston and 185.9 miles from London. ## What happens when our technicians get to you around Barbers Moor - The replies change the work, which is why our engineers ask before giving a price: what went in, how much of that, and if the engine has run. - Our engineers clear that tank of the tainted fuel. - What is left in your system shouldn't be what caused the problem, and so the fuel lines get flushed and the fuel filter cleared. - We pour fresh diesel in and prime the fuel system. - Your engine is started and tested to confirm it runs smoothly on fresh diesel. That leaves your car ready to pull away. All of this is done where the car is, so it never needs to go to a garage, and when it has been noticed early, long-term damage is very rare. Three things help when you ring from near Croston War Memorial: which side the filler is on, whether a van can stand next to without blocking the road, and if your engine has run since you filled up. On-street is the usual place we work, and so the location itself is seldom the trouble — we'd much rather deal with a tight parking spot than with a car that has been driven to somewhere more convenient. We'll drain your Dacia Duster, change the filter where there is a serviceable one, flush the lines then put clean fuel through the entire system, since by this point the worst of it is waiting in your lines instead of in the tank. ## Barbers Moor AdBlue removal is a different job If what got in was AdBlue rather than petrol, the opening instruction is the same — never fire it up — yet the problem isn't. Petrol dilutes the diesel and takes away the protection the fuel system relies on. Corrosion and deposits are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water. Often the more significant of the two, AdBlue — and the detail sits on its own Barbers Moor page. Both are ours to deal with. New locations are where this happens most, and the reason is mechanical not slapdash: the narrower petrol nozzle fits a newer diesel filler neck with almost no resistance at all. Filled up by Croston Sports Club without thinking, in a diesel Mercedes A-Class you have had for two days? Call us where you are. Hire and courtesy cars often get driven further before anyone spots it, and miles is what settles how much petrol gets to the fuel injectors. ## Barbers Moor costs for a petrol-in-diesel fuel drain What moves the price is listed below, as the job is not one job and we cannot frankly put a single figure on this page. - Whether the engine has been run or driven. This is the main one. - How much of the wrong fuel got in, set against how much that tank holds. - The kind of fluid in the tank, petrol or AdBlue. - Whether our van can sensibly reach the car and work on it, which depends on where the car is. The car, the quantity, whether it has run — give us those and the answer comes back clear rather than as a range. If it isn't pressing — the car is at home and going nowhere — works too. By now your tank is the least of it. Run a diesel and the mixture goes into your filter, into the lines, into your pump, into the rail — and none of that leaves with the tank contents. A diesel Vauxhall Insignia that made it by St Michael's and All Angels needs its circuit cleared. Clearing isn't the same thing. ## Questions we get about petrol in diesel around Barbers Moor ## Fuel drains on a Barbers Moor petrol station forecourt A fair portion of this work happens there, so yes. Routinely, provided the site consents: Gulf, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our technicians can work in that location is something our technicians answer there and then. ## A few litres of petrol in a diesel — too much? Litres aren't the yardstick. Ratio is, and a lot more than either, it matters if anything has been run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been sucked right through, or has it not? ## I drove it after putting petrol in my diesel. What next? Stop safely. Off. Nothing after that. It is fixable much more frequently than drivers assume, even though driving is what moves the problem from that tank into the pump and injectors — and the single most helpful thing you can do now is not restart it. ## Fuel drains and manufacturer warranties A manufacturer's warranty outlasts a drain then flush done to a proper standard, which is no modification at all. Another good reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a disagreement with one. ## Can I just add two-stroke oil and drive home? What petrol has thinned isn't put back by two-stroke oil, which is an old fix for a different problem. So no. The tank still has petrol in it later, and the pump still has to live with it. ## Main dealers and petrol in a diesel Not at all. Our engineers drain and clean your car wherever it is, so there's no need to bring it to a franchised dealer. ## Standing next to it? Your engine stays off. If you have already driven it, pull over somewhere sensible, switch it off then keep it off. This is recoverable from far more often than motorists fear, and a still, cold car is the best position to be in. Emptying misfilled vehicles, Barbers Moor and the rest of Lancashire, wherever they are. Kerbside. Forecourt. Home.
