If you have not turned on the motor yet, do not. A drain and nothing else is almost always what a vehicle requires while the petrol is still sitting in your tank and the engine has not been started, which is why it's the coming few minutes that count, not how much went in. Petrol in Diesel goes to the vehicle wherever it has come to rest in Whitwick or the remainder of Leicestershire, on the forecourt, by the roadside or on a private drive, and drains and flushes it there. Just one call to us is sufficient: we can explain what follows after this. Make this first. ## What to do next about petrol in a diesel - Whenever you drive, the pump and the fuel injectors suffer. This is why you do not start the car, and why you do not depend on it once it has started. The trick about petrol in a diesel especially — the part people get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol motor normally cannot run at all, which stops the driver and stops the damage with them. This one lets you drive on. - Two jobs, diesel: it burns, and on the way through it keeps the injection pump and injectors oiled. Petrol only manages the one. That is why the ignition remains off too — switch it on and you often prime your system, and that is petrol leaving that tank for exactly those components. - Topping up removes nothing. It hands you a larger tank of the same blend, since a diesel fuel system does not handle petrol by percentage as that guidance assumes — so never put diesel on top to weaken it. Grade is irrelevant too: super unleaded is petrol. - Remain where you are if you sensibly can. A vehicle that hasn't shifted is the simplest one to handle, and we'd rather drive to a difficult spot than have it started. If you are stopped on the verge on Hall Lane, switch those hazards on then keep the vehicle there. - Know where you are before ringing. A postcode starting LE67 5, and the name of whatever is next to you. Otherwise the technician circles rather than turning up. - Dial 0333 366 0103. Prepare for three points — what went in, approximately how much, and whether the engine has been started. The responses shape whatever comes after. The trip back would more or less double it, for no purpose at all. One commute has already sent a real volume of petrol-thinned diesel through your high-pressure pump of your Renault Megane. So leave the car where it sits. Ring us from the platform if that is easier — nobody needs you standing over the car outside Loughborough whilst our technicians work, and tonight beats finding out on Monday. ## Can petrol be taken out of your diesel on a forecourt? The job begins at a forecourt, generally. Often enough it wraps up at one as well. Our technicians work on petrol station forecourts routinely, with the site's agreement, so if you are still at Shell that is typically where this drain takes place. A filling station is the single place the mistake can be halted before your motor has fired. Anywhere else — a car park, a private drive, a lay-by — the vehicle was started and moved to get there, which means fuel was pulled from your tank, through the filter and into your high-pressure pump. That's not a catastrophe, and our engineers can still deal with it where it is. It does mean your lines and the filter need cleaning as well as your tank, and that is determined by the few seconds between seeing the till receipt and going for your key. Out from the petrol pump, the next motorist can get through — so yes, let the attendants help you move the car. Worth it. Starting the car for four car lengths? Don't. ## Do our engineers reach your end of Whitwick? New Swannington, Thringstone, Coalville, Swannington, Agar Nook — all of them on our journeys that bring us across to Whitwick too, a village. Our technicians still come. Those places above are only the closest neighbours, and a page exists for the majority of towns in Leicestershire, so an absence from the list isn't an absence from the coverage. Assuming is the habit to skip, especially on the boundary or somewhere your phone goes wrong. Phone to check. This map shows the area the page covers. We operate roadside, on forecourts, on driveways and in car parks throughout all of it, and the car does not need to move to us. Put diesel in a petrol car and mostly it will not run, so the motorist stops there and the harm stops with them. Flip it — petrol into a diesel — and the thing starts, idles and drives off as though nothing had happened, whilst the high-pressure fuel pump works without the lubrication the fuel is meant to be giving. That's the trap, and it's why the diesel Peugeot 308 will have seemed entirely ordinary coming back from Holy Cross School A Catholic Voluntary Academy. They always do. From the driver's seat there's nothing to alert you about, so nothing alerts you. Phone us with about how far you travelled, and how hard; the second answer counts more than the first. ## Whitwick: stuck where you parked Some drivers find no safe spot to pull in at all. Set off, then realised? Ended up by the verge of Vicarage Street, or stuck in some lay-by with the hazards going? That's a normal call here. Not an unusual one. Fine where you are? Sit with it. Not okay? Get out and away from it. Never restart it to get to a nicer spot. It will go — a diesel on petrol normally obliges — and each mile of obliging draws that blend deeper into your fuel system. Carrying on does the car far more harm than our van heading out to a difficult spot, and that's no trouble for us. ## Run it already? Pull over, and check below This is where the M1 comes in — under 5 miles from Whitwick. Lost power, a rough idle, some smoke: those are the symptoms when they come, instead of a clean stop — and a misfuelled diesel will frequently take you onto it and some way along before anything feels wrong at all. Take the first exit that's sensible, pull up there, and never start the vehicle to move it. Long trip? Anything close to the under 15 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of that got to by the contamination. Say that on the phone, since it changes what goes in our van. Here is the entire process. Diesel needs enough body to seal the close clearances it goes through, and petrol takes that away. That's it. Which accounts for the ordinary Whitwick Football Pitches call — a diesel BMW 1 Series, out there without a murmur and back down on power, uneven 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 rather than building, and delivery comes weaker, later, less even than your engine was engineered round. Not a failing motor, though. Fuel that has stopped acting like diesel. Put that right and it stops. ## Where is Whitwick? Whitwick is a village in Leicestershire, situated near lakes and surrounded by other communities such as New Swannington and Thringstone. Whitwick sits at an elevation of 144 metres, approximately 11.8 miles northwest of Leicester. Whitwick has a population of around 1727 people, predominantly living in semi-detached housing. Whitwick is located in the East Midlands region, about 99.8 miles north of London. ## What our technicians do when our engineers get to you around Whitwick - Three things get asked before any quote — your fuel that was put in, the amount, and if anything has been run since. Each answer changes the work. - Away goes the polluted fuel. - Lines purged, filter cleared. Whatever remains after that isn't the thing that created the issue. - New diesel goes in, and then the fuel system gets bled. - Once it is fired up, we confirm it runs properly on new diesel. From that point, you are ready to set off. There is no need to go to a garage at any stage, as the work is all done where the vehicle is, and when it is noticed quickly, long-term damage is very unusual. Pulled off the forecourt, read the till receipt, and parked the diesel Vauxhall Astra up by Whitwick Methodist Church a couple of hundred yards later? That is about as well as this goes once the engine has turned. Call us and leave it off. The short distance truly assists, but it was still a start and a drive, so weakened fuel has arrived at your filter and the pump — which is why our technicians clean your lines instead of only draining the tank. ## A separate problem: AdBlue in a diesel tank around Whitwick If what was put in was AdBlue instead of petrol, the first step is unchanged — do not fire it up — yet the issue isn't. Petrol does two things to diesel: dilutes it, and strips out the lubrication the system depends on. AdBlue is urea dissolved in water, and in a diesel tank it causes corrosion and build-up instead. Both are ours. There's a separate Whitwick page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two. The narrower petrol nozzle goes into a newer diesel filler neck with almost no resistance at all, which makes this mechanical not slapdash. Unfamiliar spots see most of that for that reason. So: topped up close to Hermitage Leisure Centre without thinking, in a diesel Ford Kuga you have had for two days? Ring us where you are. Hire and courtesy cars tend to get driven further before anybody notices, and distance decides how much petrol ends up at the fuel injectors. ## Budgeting for a petrol-in-diesel fuel drain around Whitwick What moves the price is listed below, since the job is not one job and our technicians can't truthfully put a single figure on this page. - Has it been started or driven? Nothing else counts for as much. - Wrong fuel in, against what the tank takes — that ratio. - Whether it's petrol or AdBlue. - Where your car is, and whether a technician can safely reach and work on it. A straight answer rather than a range is what you get for telling us three things: your car, the quantity, and whether it has run. Motor at home, going nowhere, nothing time-critical about it — is ideal for that. ## Petrol in diesel questions from Whitwick drivers ## At a petrol station around Whitwick, can you do a fuel drain there? Plenty of what we do happens nowhere else. So yes. Our engineers visit Morrisons and the other forecourts locally regularly, with the site's consent — tell us which one you are at when you ring and we will tell you whether we can work there. ## A couple of litres of petrol in a diesel — too much? It depends on the proportion rather than the litres, and a lot more on whether the motor has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that blend been pulled right through, or has it not? ## Already driven it with petrol in your diesel? What now? Pull in somewhere sensible, switch off, and keep the car off. It's fixable much more often than drivers assume, even though driving is what shifts the trouble from that tank into your pump and injectors — and the single most helpful thing you can do now is not restart it. ## Fuel drains and manufacturer warranties A drain then flush carried out properly isn't an alteration and doesn't cancel a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off. ## Can I just add two-stroke oil and drive home? What petrol has diluted isn't restored by two-stroke oil, which is an old remedy for a separate problem. So no. Afterwards? Still petrol in your tank, and a pump that has to put up with the stuff. ## Do I need a main dealer for petrol in a diesel? You don't need one. The car is drained and cleaned wherever it is, with no need to bring it to a dealership. ## You, and the vehicle, still together? That engine remains off. Already driven it? Then pull in somewhere safe, turn off, and let the car remain that way. A still, cold car is the best place to be in, and this is recoverable from far more commonly than people expect. Throughout Leicestershire and in Whitwick: call-out fuel draining, at home or on the forecourt or at the kerbside.
