Don't Start It Don't start the motor. If the petrol is still sitting in that tank and your engine has not been started, a drain is nearly always all it takes — and that gets decided in the following few minutes, not by how much got in. Petrol in Diesel drains and cleans misfuelled vehicles where they stand, all over South Shore and the rest of Lancashire, on the forecourt, by the roadside or on a drive. We can explain what your next step will be. Phone — this goes ahead of anything else. ## Petrol in a diesel: what to try now - Give a petrol motor diesel and it will generally fail to run at all, so the driver stops there and so does the damage. Give a diesel petrol and the thing starts, it ticks over, it pulls away — fine for a few miles. Drivers have that reversed, which is the part they get wrong about petrol in a diesel specifically. So never start the car. And having started, do not trust it: the fuel system is grinding as you drive. - Flicking the ignition on commonly primes that system, and priming is what draws petrol out of the tank then into your pump and injectors. Those are the components diesel keeps protected on its way through, before it burns. Petrol manages the burning and none of the lubricating. Leave your ignition alone. - Topping up clears nothing. It gives you a larger tank of the same blend, since a diesel fuel system doesn't tolerate petrol by percentage the way that advice suggests — so don't tip diesel on top to weaken it. Octane is immaterial too: super unleaded is petrol. - Our team would much rather drive to an awkward spot than have it started — so if you sensibly can, stay put. Nothing is quicker to deal with than a car that has not shifted. On the verge on Kingsway, that means hazards on then leave it. - A van showing up rather than circling hinges on two things: a postcode that starts FY4 2, and whatever is nearest to you with a name on it. Get both prepared before you dial. - Three answers settle the entire visit: the stuff you tipped in, the ballpark amount involved, plus whether anything has been running since. The number is 0333 366 0103. ## On the forecourt: draining petrol from the diesel Much of this work starts at a pump, so a fair part of it gets finished there. The drain typically gets done on the spot. Still on the forecourt at Esso? Given the station's agreement, that is a place we work, and regularly. A filling station is the only place the mistake gets halted before the engine has started. Fuel pulled out of that tank and through the filter, all the way to the high-pressure pump, is what happens when the motor is switched on and your car is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush includes the fuel filter and the fuel lines along with your tank. That is still not a catastrophe, and our technicians deal with it where the vehicle sits. What settles it is whether the key was turned in the seconds after the till receipt was checked. The attendants will normally offer to wheel the car out from the pump so the next driver can get by. That is worth doing. Starting the car just to roll four vehicle lengths is not. Car parks like the one at Lidl are somewhere our engineers visit frequently, and your fuel is hardly ever the awkward part. The bay is: vehicles either side, a trolley shelter behind, sometimes a height barrier on the way in that decides whether our van can get to you at all. So tell us how boxed in you are when you ring, and which way your car is pointing. If we can't work next to your diesel Volkswagen Passat we will move it without starting it — and that isn't fussiness about a handful of seconds of running. Any start primes the fuel system and draws more of the mixture out of the tank and towards the pump, and so a vehicle shunted twice into a nicer space has gradually turned into a harder job than one left exactly where it stopped. ## South Shore plus the areas beside it Being a residential suburb, South Shore gets a routine visit, and the villages close by come with it on that same round: Squires Gate and Hawes Side, Marton Fold and Common Edge, Revoe. Not on this list? That tells you nothing. The places above are only the closest few, and most locations around Lancashire have a page of their own somewhere on our site. Presuming is the mistake to resist, above all on the border or somewhere your satnav goes wrong. Phone to enquire. This map shows the area this page spans. Roadside, forecourt, private drive, car park: all of it is ground we serve, and none of it requires the car to travel to us. ## Stuck on the roadside around South Shore Some drivers have no safe place to pull over whatsoever. A routine call for us instead of a rare one: noticed after setting off, finished up along the verge on Coniston Road or at a lay-by with your hazards flashing. Clear of the car if it is not wise to be there, with it if it is. Every mile a diesel obliges you for on petrol drags the blend further into the system — and oblige it frequently will, which is why your engine doesn't get restarted to limp somewhere better. However tricky the place, it's no trouble for us to get to it, and that's a lot better for the vehicle than driving on. Park it there overnight. Phone first thing. Nothing about a diesel Nissan Qashqai sitting in the car park by The Spen Dyke deteriorates while it sits, tank of petrol or not, and this job remains a simple one right up till the moment it gets taken home. The question our technicians arrive with is about that drive there: a cold engine over a short run is where petrol ignites least well, and whatever fails to burn can get past the piston rings into the engine oil. ## Petrol in a diesel, and the vehicle has rolled Here is where the M55 comes in, under 3 miles out of South Shore. It will usually get you onto it, and some way along, before you spot a thing. Then it's some smoke, an uneven idle and power draining away — not a neat stop. Misfuelled diesels rarely give you one of those. Take the first junction that is safe, stop there, and do not start the car to move it. On a longer trip — anything close to the under 15 miles to the nearest city — assume the petrol has been through the fuel filter, your pump and the injectors, and tell us when you phone. It affects what our engineers bring. Pull over somewhere safe, switch off and phone us. Fine on the way out to Watson Road Park, flat on the way back? Then look at the tank. Petrol weakens diesel; runnier fuel seeps past the precision components that build injection pressure; and the further the diesel Audi A4 travelled, the less of that pressure it held. ## A little about South Shore South Shore is a coastal suburban area in Lancashire, situated near the city of Preston and close to nearby places such as Squires Gate and Hawes Side. South Shore has a population of approximately 6645 people and is characterised by predominantly semi-detached housing. South Shore sits at a low elevation of around 12 metres above sea level, looking out over the coast. South Shore is located about 199.7 miles northwest of London, making it a relatively distant suburb from the capital city. ## The job around South Shore, step by step - We establish what got in, how much, and if your engine has run. The answers change the work, which is why we ask before giving a price. - The polluted fuel comes from the tank. - Fuel lines are cleaned through and the fuel filter cleaned, leaving nothing in the system that caused any of this. - Fresh diesel goes in, and then the system gets bled. - The motor is fired up and checked to make sure it runs smoothly on new diesel. From there, you're ready to drive away. We do everything wherever your car has ended up, which means it never has to go to a workshop, and if it has been noticed soon, it is very rare for there to be lasting damage. Three things help when you phone from near Lytham Road Unitarian: which side the filler is on, whether a technician can park next to without blocking the road, and if the engine has run since you filled up. On-street is the commonest place we work, so the location itself is rarely the issue — we would much rather deal with a cramped parking spot than with a motor that has been driven to somewhere more handy. We'll drain the Ford Focus, change the filter where there's a usable one, flush your lines and put fresh fuel through the whole circuit, as by this point the worst of it is waiting in your lines rather than in your tank. ## AdBlue in your diesel tank by mistake, around South Shore? Do not crank it: that first rule holds whether what got in was AdBlue or petrol. What differs is the issue itself. Petrol dilutes the diesel and strips the lubrication the system relies on. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and build-up in its place. AdBlue removal around South Shore has a page of its own with the full story on it, including why it's often the more significant of the two. We handle both. ## South Shore prices for a petrol-in-diesel drain Honestly, no single number fits on a page like this. The job varies. Here is what changes it: - Has it been run or driven? Nothing else matters for as much. - How much of the wrong fuel was put in, judged against how much the tank takes. - The kind of liquid in the tank, unleaded or AdBlue. - Where the vehicle is, and if our van can safely reach and work on it. The vehicle, the amount, whether it has run — give us those and the answer comes back clear and not as a range. If it isn't pressing — the vehicle is at home and going nowhere — works too. That sluggishness is the fuel failing to build pressure fully, not the motor packing up — and with no dashboard light for it, motors in that position normally get driven a second time before somebody calls. Don't. A few streets is all it got: throttle gone limp, idle turned uneven, and a diesel Citroen C3 now sitting close to Blue Flyer. Switch it off and phone us. ## Questions we get about petrol in diesel around South Shore ## Fuel drains on a South Shore petrol station forecourt Yes — forecourts are where a big portion of this takes place. Permission from the site is the condition. Given that, a forecourt like Morrisons is somewhere we're often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there is possible. ## How much petrol is too much for a diesel? Litres are not the measure. Ratio is, and far more than either, it counts whether anything has been run. What decides how much work is needed is if that mixture has been pulled through the system — since even though five litres in a nearly empty tank is a different matter from five in a full one, either way that's the question. ## Petrol in my diesel, and I have driven it Pull in somewhere sensible, switch off, then keep the vehicle off. It is fixable a lot more commonly than people fear, even though driving is what moves the issue from your tank into the pump and injectors — and the single most useful thing you can do now is not restart it. ## Fuel drains and manufacturer warranties It isn't a modification, so a drain and flush carried out properly does not void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one. ## Two-stroke oil in that tank, and then home? Two-stroke oil solves a different fault, and an old one at that. Nothing it does puts back what petrol thinned. No. After that? Still petrol in that tank, and a pump that has to cope with the stuff. ## Main dealers and petrol in a diesel Wherever your car is, our engineers drain and flush it there, so a trip to the main dealer does not come into it. ## Still with your vehicle? Never switch the car back on. Turn it off somewhere sensible and keep it off, if you have already driven it. This is recoverable from far more often than people fear, and a stationary, cold vehicle is the best place to be in. Across Lancashire and around South Shore: on-site fuel draining, at home or on the forecourt or at the roadside.
