A drain and nothing more is almost always what a vehicle requires while the fuel is still inside your tank and your engine has not yet been started, which is why it is the next few minutes that count, not how much was put in. Petrol in Diesel comes to your car wherever it has stopped in Stonequarry or the remainder of West Sussex, on the forecourt, at the roadside or on a private drive, and drains and flushes it there. Our technicians shall tell you what your next stage will be. Phone — it goes before anything else. ## Petrol in a diesel: what to do first - Feed a petrol engine diesel and it will normally refuse to run at all, so the motorist stops there and so does the harm. Give a diesel petrol and the engine starts, it idles, it moves off — fine enough for several miles. Motorists have that muddled, which is the part they get wrong about petrol in a diesel specifically. So do not fire it up. And if started, do not rely on it: the fuel system is grinding while you drive. - Flicking your ignition on often primes that system, and priming is what pulls petrol out of that tank and into your pump and injectors. Those are the components diesel keeps oiled on its way through, before it combusts. Petrol manages the burning and none of the protecting. Leave the car's ignition off. - That guidance supposes a diesel fuel system copes with petrol by percentage. It does not. Pour diesel on top and nothing at all is taken out; what you get is a fuller tank of the same blend. And no, the type makes no difference — super unleaded is simply petrol. - Wait where you are if you safely can. A motor that hasn't shifted is the quickest one to sort, and we would much rather get to an awkward place than have it started. If you are pulled up on the verge on Wilderwick Road, put your hazards on and keep it there. - The van turning up instead of circling rests on two things: a postcode beginning RH19 3, and whatever is next to you with a label on it. Keep both prepared before you phone. - Three facts decide your whole job: the fuel you put in, the approximate amount involved, plus whether it has been turning since. The line is 0333 366 0103. ## Clearing petrol from your diesel on a forecourt It begins at a forecourt, generally. Often enough the work ends at one too. If you are still at the forecourt at JET, that is usually where the drain gets done — we work on station forecourts regularly, with the station's agreement. A forecourt is the single location it can be caught before the motor has fired. Fuel sucked out of the tank and through the fuel filter, right to the high-pressure fuel pump, is what occurs when the engine is started and the vehicle 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 your filter and your lines along with your tank. That's still not a calamity, and we sort it out where your car is. What decides it is whether the ignition was turned in the seconds after the receipt was read. Clear of the pump, the next motorist can get past — so yes, let the staff help you roll the vehicle. Well worth doing. Cranking it just for four car lengths? Not a chance. ## Places we reach in Stonequarry Being a residential suburb, Stonequarry sees a regular call, while the places nearby come along on the same trip: Blackwell and Dormans Park, East Grinstead and Baldwins Hill, Hammerwood. Not on this list? It tells you nothing. The names above are just the closest few, and the majority of places around West Sussex have a page of their own somewhere on our site. Assuming is the mistake to skip, especially on the border or somewhere a satnav fails. Ring us to check. That map shows the patch the page spans. All of that is ground we cover: a roadside, a forecourt, a driveway, a car park. You do not bring your car anywhere. Someone will urge you to shift it out of that gateway and deal with it later. Don't. A wrongly fuelled diesel Skoda Octavia on the zig-zags at Blackwell Primary School is an inconvenience; the same motor restarted three more times to be polite is a fuel system instead of a tank. Each restart primes your lines and pulls more petrol through the filter then into your pump. Leave it there, let people complain, and phone us. ## Stuck by the kerbside somewhere around Stonequarry? Some drivers get no safe spot to stop at all. Set off, then realised? Ended up on the verge beside Sandhawes Hill, or sat in some lay-by with your hazards flashing? That is a routine call here. Not a rare one. Okay there? Remain beside it. Not okay? Move out and away from it. Do not fire it up to get to a safer spot. It will go — a diesel on petrol usually obliges — and each mile of obliging pulls the mixture deeper into the system. A technician driving to an awkward spot is no problem for us, and it's far better for your car than carrying on. Three replies determine much of the work: what was put in, about how much, and whether the motor has run since. We ask for those answers as soon as we get to the vehicle in the car park at the pub in the village. Then the tainted blend comes out of that tank, the lines are rinsed, and where your Peugeot 308 has a replaceable filter, it comes off. After new diesel is in and the system primed, we start it and confirm it runs properly before you drive away. ## Driven it already? Pull in, then see this This is where the local M23 comes into it — under 10 miles from Stonequarry. It will usually get you onto it, and some way along, before you notice a thing. Then it's some smoke, an uneven idle and power ebbing away — not a tidy stop. Wrongly fuelled diesels seldom give you one of those. Never start it to reposition. Come off at the first safe exit then turn off. It changes what our engineers bring, and so tell us when you phone: on a longer trip — anything approaching the under 25 miles to the closest city — assume the contamination has been through the filter, your pump and the injectors. Out there happy, back sluggish. If that was the trip to Swites Wood, look at the tank. Diesel gets thinned by petrol, and thin fuel leaks past the tight gaps meant to build injection pressure — so every further mile the diesel Mercedes E-Class covered, the less pressure it held onto. Somewhere sensible, switch off, ring us. ## Where is Stonequarry? Stonequarry is a suburban area in West Sussex, situated inland at an elevation of 132 metres, and forms part of the commuter belt around London and Brighton. Stonequarry lies near several other communities, including Blackwell, Dormans Park, and East Grinstead, and is characterized by its predominantly detached housing stock. Stonequarry is home to a population of approximately 2829 residents, who enjoy its relatively rural setting within easy reach of larger urban centres. ## When our engineers reach you around Stonequarry: what happens - Our technicians establish what was put in, how much, and whether the engine has run. The replies change the work, which is why our technicians ask before pricing. - Our technicians empty the tank of the polluted mixture. - What is remaining in the fuel system should not be what created the problem, so the lines get rinsed and the filter cleaned. - Fresh diesel goes in, and then the system gets primed. - It is fired up with fresh diesel in it, and our technicians confirm that it is running smoothly. The vehicle is then ready for you to drive away. Our technicians do all of it wherever the vehicle has stopped, which means it never needs to go to a garage, and when it has been spotted early, it is very unusual for there to be long-term damage. ## AdBlue in a diesel tank in Stonequarry is a distinct matter If what was put in was AdBlue rather than petrol, the first step is unchanged — never start the vehicle — yet this fault isn't. Petrol thins the diesel and takes away the protection your fuel system depends on. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and deposits in its place. AdBlue removal in Stonequarry has a page of its own with the detail on it, including why it's often the more significant of the two. Our technicians deal with both. Rattling, a lumpy idle, white smoke, a throttle gone limp. That is a misfilled diesel BMW 1 Series telling you what's wrong. Turn off where you have stopped, close to East Grinstead WWII Memorial or anywhere else, and never restart it to find a better location. ## What a petrol-in-diesel fuel drain will cost in Stonequarry What shifts the figure is set out below, as the job isn't one job and we can't honestly put a single price on this page. - This is the main one: whether your motor has been run, or driven. - The tank's capacity, set against how much of the wrong fuel got into it. - AdBlue or petrol, whichever was put in. - Where is it? And can our van get to it and work there sensibly? Tell us the car, the amount and whether it has run, and you'll get a firm answer instead of a range. For the car at home that is going nowhere and isn't urgent, works too. By this point that tank is not where most of the trouble is. Once a diesel has run, that blend is in the fuel filter, the lines, the pump and the rail — and it doesn't come back out with your tank contents. A diesel Citroen C3 that got close to Jubilee Community Center Food Bank needs your system purged, not cleared. ## Stonequarry motorists ask us these about petrol in diesel ## At a petrol station in Stonequarry, can you do a fuel drain there? Yes — forecourts are where a fair share of this happens. Tell us which one you are at when you call and we'll tell you whether our technicians can work there. With the station's permission our technicians visit Esso and the other forecourts around town regularly. ## How much petrol is too much for a diesel? Litres are not the measure. Ratio is, and much more than either, it counts if anything has been run. An almost empty tank with five litres in it, against a full one with the same five: separate scenarios, certainly. Either way, the work needed comes down to one thing, which is if the system has had that blend pulled through it. ## I drove the car after putting petrol in my diesel. What now? Stop sensibly. Off. Nothing after that. Driving takes the trouble along — out of the tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one genuinely helpful thing left to you isn't restarting the car. ## Fuel drains and manufacturer warranties A drain then flush carried out properly is not a modification 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 turned off. ## Can I just add two-stroke oil and drive home? No. Two-stroke oil is an old fix for a different issue and it doesn't put back what petrol has diluted. That tank still has petrol in it afterwards, and the pump still has to put up with it. ## Does petrol in a diesel have to go to a main dealer? You do not need one. The car is drained and cleaned wherever it is, with no need to take it to a franchised dealer. ## You, and the vehicle, still together? Shut off is the way it stays. If you have already driven the vehicle, pull over somewhere safe, switch it off then leave it off. A parked, cold motor is the best position to be in, and this is recoverable from much more frequently than motorists assume. Call-out fuel draining around Stonequarry and across West Sussex — at the kerbside, on the forecourt or at home.
