Not started? Then less worried than you likely are. Everyone around Raygill begins with "have I ruined it?", and the honest answer is normally no: petrol resting inside that tank of any diesel stays harmless until priming, cranking or driving pulls it into your fuel system. Leave the engine off then phone Petrol in Diesel — that is how you keep it that way. Further down, this page sets out what petrol really does inside a diesel, how far it may have gone, and how to stop it happening to you again. ## The engine and petrol in a diesel: what goes on Two jobs fall to diesel on its route round a motor. It protects first, and only then does it burn. What keeps the surfaces inside the high-pressure pump and your injectors from grinding against one another is the diesel flowing through them — they are built to extremely fine gaps. Badly at the first, not at all at the second: that's petrol. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, so a pump on the blend wearing itself. It's equally made to resist igniting under compression — the opposite of what a diesel needs — which is where you hear the knocking. The shape of the problem is plain once you put those together. It's circulation that does the harm, not contact. All a tank with petrol in it amounts to is a fuel issue. A pump that has been working on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds travels on with the fuel to your injectors downstream. ## Raygill, petrol in a diesel: four cases, from mild to significant Fuelled up, not once started. The best case there can be. That petrol is inside the tank and only your tank, and the task is a drain and a flush where the vehicle sits. This is the one scenario that can only truly take place at a forecourt, because anywhere else your car has been driven to get there. A brief spell of running, or just the ignition on. Your system has been bled, so petrol has left the tank and reached the fuel filter and the fuel lines. Normally nothing more than draining, flushing and seeing to the fuel filter, so still straightforward. The pump has worked a few miles on weakened fuel — that's what driving the vehicle does. The work is that tank, your lines, the filter and fresh fuel through the whole circuit, and how hard your car was driven counts as much as how far. A school run to Lothersdale Primary School is one matter. Very different once more: a run to Bradford, under 25 miles away, or some distance on the M65, under 10 miles from Raygill, where the motor never stopped labouring hard. Driven on until it protested — clattering, smoke, an uneven idle, a soft throttle. That's your motor telling you its fuel has stopped behaving like diesel. Leave it wherever it has stopped: a lay-by, a side street, the verge on Winter Gap Lane. A vehicle pulled over quickly very seldom has long-term damage, because the fuel drain and the flush-through, which still go first, sort it out. ## Petrol in a diesel stories Raygill people hear Myth: topping up to full with diesel makes it fine. It doesn't. Nothing is removed by topping up — you are left with a fuller tank, still the same mixture. Percentage isn't how a diesel fuel system copes with petrol, whatever that advice assumes. Myth: a modern diesel copes with a bit of petrol. Rather, the reverse. A modern diesel runs its fuel through smaller parts at higher pressure, which makes the lubrication count more, not less. "It starts, it drives, and so there is no harm" — the myth that trips up more motorists than any other. The driver of a petrol motor fed diesel normally stops, since it will not run, and the damage stops with them. Feed petrol to a diesel and it generally fires up, idles and drives away as if nothing happened — all the while its pump wears. Being able to run isn't proof of being fine. Myth: a two-stroke additive lets you to drive home. It was an old fix, supposed for another problem. The petrol is still inside your tank afterwards, and whatever it has thinned isn't put back. The next start sends petrol back round the pump out of your lines and the fuel filter, where some of it ends up once the engine has been run. That's why draining the tank yourself doesn't sort it — a myth. It is also truly risky to drain petrol into a can by the roadside. ## Petrol in a diesel: how does it take place? No one does it on purpose, and it's rarely carelessness. One way only, because of the nozzles: the narrower petrol one slips inside a diesel filler with almost no resistance, while the diesel one generally will not fit a petrol vehicle. That's how the forecourt makes it straightforward. When routine and the car stop matching, it occurs. A motor that is new to you — hired, on loan as a courtesy car, or just bought. A household with one petrol and one diesel on the driveway. A forecourt you know, but with its pumps arranged differently. A hurried fill en route to Cononley with a train to catch. Years of petrol cars behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when. Your hand does what it has always done once you add rain, a phone call or a back seat full of kids. ## Avoiding petrol in a diesel next time you fill up around Raygill - Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most usually do. Check the pump's label; the colour is just a clue. - In a vehicle you do not know, look inside the flap over the filler or at the cap before your first fill: plenty of motors state the fuel there. - One of each in the house? Label the key to your diesel — a coloured fob, a sticker — because meaning to remember is not enough. - "Diesel", aloud, before you pick up the nozzle — every time a new or hired car gets its first tank. It seems silly. It does the trick. - Put your phone away. This is an easy mistake to make whilst you're thinking about something else. - Up to a point, a misfuel inhibitor helps: some diesels have a filler built to reject a petrol nozzle, and aftermarket devices exist for the remainder. Treat it as a safety net, then keep reading the pump. - Noticing it mid-fill? Stop at once. A thinner mixture results from less petrol in that tank, yet the next stage stays the same: do not fire it up. ## Already put petrol in a diesel in Raygill? The order of things is brief, then. Don't turn your ignition on, and don't crank it. If you are still at the forecourt — Total or anywhere else — ask the staff to help you push it clear of the pump. Ring 0333 366 0103 next, with three facts — your fuel, the rough amount, and if it's run. If it was AdBlue and not petrol, say so. That is a separate fault — corrosion and deposits instead of lost protection — and it has its own page for Raygill. ## Raygill petrol in a diesel jobs: why one costs more than another The four scenarios above are four different jobs, so no single quote for this would be fair. The scenario itself does most of the work of moving the cost. After that it's the ratio — how much petrol was put in against how much the tank takes — and after that where the vehicle is and whether a technician can get to it safely. Ahead of any quote, not after, come three queries: your fuel that went in, its volume, and whether it's run. That is why. Their answers are what change a range into one firm number. ## About Raygill and its setting Raygill is a locality in North Yorkshire, situated on the riverside at an elevation of 228 metres, with detached housing being the predominant type of accommodation.
