Don't Start It With your tank still holding the fuel and your engine not yet run, nearly every job requires only a drain, so keep your engine off. That outcome is decided in the minutes immediately after the fill-up, and not by the amount that went in. Across Lightwood and the rest of Staffordshire, Petrol in Diesel drains the vehicle and flushes it where it is, whether by a roadside, on a driveway or at a forecourt. Contact us before all else starts, and you will know what follows next. ## The first five minutes: petrol in a diesel - Give a petrol motor diesel and it will generally not run at all, so the driver stops there and so does the damage. Feed a diesel petrol and the thing starts, it ticks over, it pulls away — all right for a few miles. Motorists have that muddled, which is the thing they get wrong about petrol in a diesel especially. So never start the vehicle. And once started, do not trust it: your fuel system is wearing down as you drive. - Turning your ignition on commonly primes that system, and priming is what draws petrol out of that tank then into the pump and injectors. Those are the components diesel keeps lubricated on its way through, before it burns. Petrol manages the burning and none of the lubricating. Leave your ignition be. - Do not pour diesel on top to dilute it. A diesel fuel system doesn't cope with petrol by percentage in the way that guidance suggests, and topping up gets rid of nothing — it merely leaves you a bigger tank of the same mix. The type makes no difference either: super unleaded is just petrol. - A car that has never moved is the simplest one to handle, and so remain where you are if you sensibly can. Stopped on the verge on Hawksmoor Close? Hazards on, then keep it there. An odd spot works for us better than a started diesel. - Before you phone, have your position. Anything nearest to you with a sign on it, plus a postcode beginning ST3 7 — that is what decides whether the technician turns up or circles. - Call 0333 366 0103. Prepare for three things — what got in, approximately how much, plus if the engine has been turned over. The answers determine all that follows. ## Clearing petrol from a diesel on a forecourt A good chunk of this job is finished at a pump, because that's where it often starts. Our technicians work on station forecourts routinely, with the site's agreement, and so if you're still at Esso that is typically where the drain gets done. A forecourt is the single spot it can be stopped before your engine has run. The few seconds between reading your receipt and reaching for the key decide how much needs cleaning. Anywhere other than a forecourt — a car park, a drive, a lay-by — your car was fired up and moved to get there, so fuel was sucked from that tank, through the fuel filter and into the high-pressure pump. That means the lines and the fuel filter require cleaning as well as your tank. It's not a calamity, and we can still put it right where the vehicle is. Staff will usually help out pushing it out from the pump, which lets the next motorist get by. Take the assistance. Shifting the car four spaces does not warrant firing the engine. ## Coverage around Lightwood As a residential suburb, Lightwood has a steady call, and its neighbours round about go along on the same round: Normacot and Florence, Meir Heath and Meir Hay, Meir. There are pages for nearly all towns around Staffordshire, and the ones listed above are simply the immediate neighbours — so yours being absent from this list means nothing at all about whether our engineers come. Contact us to ask rather than guessing — boundaries particularly, and wherever your satnav tends to misread. Check our map for the ground covered on this page. The car does not need to travel to us. Our technicians work across the lot — kerbside, forecourts, driveways, car parks. ## Lightwood: broken down where you stopped Not everyone has the chance to pull in somewhere safe. A routine call for us rather than a rare one: realised after setting off, landed by the verge of Gardenholm Close or at a lay-by with your hazards flashing. Wait by your car when it's wise to wait in it, and out of the car if it's not. Never fire up the motor to limp the car somewhere safer — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing the mixture further into the fuel system. A van driving to an inconvenient spot is no bother for us, and it is far better for your car than pressing on. Straightforward job, this one — till somebody takes it home. A diesel Ford Focus left outside New Florence with petrol in the tank loses nothing by sitting there overnight, so park it and ring us once it's light. Expect a query about that trip there, though. Short and chilly is exactly where petrol fails to burn, and what won't burn can get past the piston rings and into the engine oil. ## So you've run it? Petrol in a diesel over a few miles This is where your M6 comes in — under 5 miles away from Lightwood. A misfilled diesel will often take you onto it and some way along before anything feels wrong, while the signs when they come are typically a drop in power, an uneven idle and some smoke rather than a clean stop. Take the next exit that is sensible, pull up there, and never restart the car to move it. It affects what our technicians bring, and so mention it when you call: on a longer run — anything near the under 5 miles to the nearest city — take it the contamination has been through the filter, your pump and the injectors. Here is the entire mechanism. Diesel needs enough body to seal the tight tolerances it goes through, and petrol takes that away. That's it. Which explains the usual Florence Country Park call — a diesel Dacia Duster, out there without complaint and back down on power, lumpy at idle, perhaps a bit of smoke. Injection systems work hydraulically as well as chemically, so your fuel has to hold pressure and not just burn; weakened, it escapes past those clearances and not building, and delivery comes weaker, later, less even than the motor was designed around. Not a failing motor, though. Fuel that has stopped acting like diesel. Put that right and it stops. ## Lightwood itself Lightwood is a suburban area situated near Stoke-on-Trent in Staffordshire, with a population of around 4200 people. Lightwood sits at an elevation of 204 metres, inland from the major cities of the West Midlands region. Lightwood is characterized by its predominantly semi-detached housing stock, and is located close to nearby places such as Normacot, Florence, and Meir Heath. Lightwood is approximately 131 miles from London, and is separated from the city of Stoke-on-Trent by a distance of around 4 miles. ## When we reach you around Lightwood: what happens - We ask first, price after. What got in? How much? Has your motor run? Those replies shape what the work actually is. - Out comes the polluted mixture. - Our technicians flush your fuel lines and clear the filter, and so what's remaining in the fuel system isn't what created the problem. - Our technicians pour new diesel in and bleed your system. - The motor is started and checked to make sure it runs properly on clean diesel. That leaves the car ready to drive away. All of this is done where your car is, so it never needs to be taken to a workshop, and when it has been caught early, permanent damage is very unusual. Our technicians flush the fuel lines instead of only emptying the tank, and the reason is that diluted fuel has already arrived at the filter and the pump: it was a start and a drive, however short. The hop truly assists — pulled off the forecourt, receipt read, a diesel Mercedes E-Class parked up by Meir Library a couple of hundred yards later is about as well as this goes once the motor has turned. Phone us then leave it off. ## AdBlue in a diesel tank around Lightwood is a different matter If what went in was AdBlue instead of petrol, the opening step is unchanged — don't start it — but the issue isn't. Thinned diesel, and no protection left for your fuel system that relies on it. That's petrol. Corrosion and build-up are what a diesel tank ends up with instead, since AdBlue is urea dissolved in water. AdBlue removal in Lightwood has a page of its own with the full story on it, including why it is frequently the more serious of the two. We handle both. Most of these occur somewhere strange, and the cause is mechanical not careless — practically no resistance meets a slimmer petrol nozzle entering a newer diesel filler neck. Two days into a diesel BMW 5 Series, a fill-up near Broadway Methodist Church that you did not think about? Phone us from where you are. Courtesy and hire cars go further before anybody clocks it, and the further they go, the more petrol arrives at your injectors. ## Lightwood pricing for a petrol-in-diesel drain What changes the figure is listed below, because the job is not one job and our technicians cannot honestly put a single figure on this page. - Whether your motor has been run or driven. This is the big one. - How much of the wrong fuel went in, set against how much the tank holds. - AdBlue or unleaded, whichever went in. - Whether our van can safely reach the car and work on it, which hinges on where the vehicle is. Tell us what the car is, how much got in, and if the motor has run. A firm answer comes back, not a range. Not pressing, with your car at home and going nowhere? Then works. It got a few streets and stopped. The throttle went limp, your idle turned ragged, and the diesel Vauxhall Insignia is now sitting near Florence Park. That sluggishness is the fuel failing to build pressure correctly not your engine packing up — and as there's no warning light for it, motors in that position usually get driven a second time before anyone rings. Please don't. Turn it off then ring us. ## Things we hear about petrol in diesel around Lightwood ## Fuel drains on a Lightwood petrol station forecourt Yes — forecourts are where a fair share of this gets done. Often, provided the site consents: BP, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that place is something our technicians answer on the spot. ## A few litres of petrol in a diesel — too much? Proportion decides it rather than litres — and more than either, whether the engine has run. What settles how much work is needed is whether that mix has been drawn through the system — because though five litres in an almost empty tank is a distinct case from five in a full one, either way that's the query. ## I drove the car after putting petrol in my diesel. Now what? Somewhere sensible, then stop, then turn off and keep it off. Driving is what takes the trouble from the tank into the pump and injectors — but it is recoverable far more often than drivers fear, and the single most useful thing you can do now isn't restart the car. ## My warranty — does a fuel drain void it? A manufacturer's warranty outlasts a drain and flush done to a correct standard, which is no alteration at all. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off. ## Could I put some two-stroke in and just drive? Two-stroke oil solves a separate issue, and an old one at that. Nothing it does puts back what petrol thinned. No. Later? Still petrol in your tank, and a pump that has to cope with the stuff. ## Main dealers and petrol in a diesel Wherever the car is, our engineers drain and flush it there, so a trip to the main dealer doesn't come into it. ## Waiting next to it? Leave it shut off. Driven it already? Then somewhere safe, stop, turn off, and no restarting the car later on. Cold, still, going nowhere: that is the best place to be in. People fear this a lot more than they need to. Mobile fuel draining in Lightwood and throughout Staffordshire — at the kerbside, on the forecourt or at home.
