Likely less than you are now — as long as no one has started it. Until the ignition primes your pump, your starter turns, or your vehicle is driven, petrol in a diesel tank simply sits there and does no harm. Which makes the truthful reply to that first Sturton by Stow query — "have I ruined it?" — normally no. Leave the engine off and phone Petrol in Diesel — that keeps it like that. The remainder of this page sets out what petrol really does to a diesel, how to judge how far it has got, and how to make sure it does not happen to you a second time. ## Petrol in a diesel: what does it do to your engine? On its way through a motor, diesel does two jobs. It protects to begin with, and after that does it burn. Built to very fine tolerances, your injectors and your pump rely on your diesel flowing through them to stop their surfaces wearing against one another. Of these two jobs, petrol handles the first badly and the second not at all. The rattling comes from petrol being designed not to ignite when compressed, which is exactly the reverse of what a diesel needs. On top of that it is runnier than diesel, it strips out the lubrication your system rests on, and any pump running on such a mix is wearing itself. Put these together and the shape of the problem is plain. It is movement that does the harm, not contact. Where that petrol is only in the tank, it's a problem of fuel, nothing more. The beginning of a mechanical one is a pump that has been running on that petrol — and whatever a worn pump sheds travels on with your fuel to your injectors beyond it. ## Sturton by Stow, petrol in a diesel: four cases, from mild to serious Filled up, never started. The best case there is. That petrol is inside your tank and just the tank, and the job is a drain and a flush where your car sits. This is the one scenario that can only truly occur on a forecourt, because anywhere else the vehicle has been driven to get there. Started for a moment, or just your ignition on. Petrol has come out of that tank and reached your filter and the lines, since the fuel system has been primed. Drain, flush, deal with the filter: still usually straightforward. Those few miles on the road meant the pump running on fuel weakened by petrol throughout. Mileage is only half of it; how hard it was driven counts just as much. Either way the work runs to the tank, the lines, your filter and fresh fuel through the entire circuit. On the school run to Sturton by Stow Primary School, the miles is short. A run as far as Lincoln, under 10 miles away, is a very different job. So is any miles on the M180, under 25 miles from Sturton by Stow, where the motor has been labouring hard throughout. Clattering, an uneven idle, smoke, a throttle gone soft: driven until it complained. The fuel is not behaving like diesel any more, and your engine is telling you. Stop where you are — on the verge on Fleets Road, at the kerb, down a side road — and do not move it. The fuel drain and flush still come first, and they take care of it: when a vehicle is stopped early, permanent damage is very uncommon. ## Stories Sturton by Stow motorists hear about petrol in a diesel 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. The assumption behind the guidance — that diesel fuel systems tolerate petrol by percentage — is wrong. Myth: a newer diesel copes with a bit of petrol. Rather, the reverse. Smaller parts and higher pressure are the way a newer diesel runs its fuel, and that makes the protection count more, not less. The myth that catches motorists off guard: if it starts and drives, it must be unharmed. Feed diesel to a petrol engine and it generally will not run, and so the motorist stops — and the harm stops with them. A diesel fed petrol generally starts, idles and drives away as if nothing has happened, whilst the pump wears. A running engine doesn't mean fine. Not so: a two-stroke additive makes it safe to drive home. It is an old workaround, supposed for another fault. What petrol has weakened stays thinned, and the petrol remains in your tank regardless. The next start draws petrol back round your pump out of your lines and your filter, where some of it ends up once your engine has run. That is why draining the tank yourself doesn't sort it — a myth. On top of that, petrol cleared into a can by the road is genuinely risky. ## How petrol ends up: petrol in a diesel A careless moment is seldom the cause, and nobody means to do it. One way only, because of the nozzles: the smaller petrol one slides inside a diesel filler with almost no resistance, whereas the diesel one mostly won't fit a petrol motor. That is how the forecourt makes it straightforward. It takes place when habit and the vehicle stop matching. Any vehicle that's new to you — hired, on loan as a courtesy car, or brand new. Households running one of each, petrol and diesel. Your usual forecourt, its pumps suddenly in a different order. Filling up in a hurry on the way to Saxilby, with a train to catch. Precisely the moment it takes place: after years of driving petrol, a driver fills a diesel Volkswagen Tiguan for the first time. Your hand repeats what it has always done when you add rain, a phone call or a back seat full of kids. ## Avoiding petrol in a diesel next time you fill up around Sturton by Stow - Green for unleaded and black for diesel is normal in the UK — yet not on each forecourt. Trust the label on the petrol pump, not the colour. - Many vehicles state the fuel inside the filler flap or on the cap, and so check there on the first fill in a motor you don't know. - A coloured fob or a sticker on your diesel's key does more than any amount of meaning to remember, in a home with one of each. - Say it before you lift it. On your first fill in a new or hired car, say "diesel" aloud before you lift the nozzle off the pump. It sounds silly and it does the trick. - Thinking about something else is when this becomes an easy mistake to make, so tuck your phone away and keep your mind on the pump. - A misfuel inhibitor helps, up to a point. Some diesels come with a filler built to block a petrol nozzle, and add-on devices exist for vehicles without one. They are a backstop, not a reason to stop reading the pump. - Noticing it halfway? Stop there and then. A weaker blend follows from less petrol in your tank, but your next stage stays the same: don't fire it up. ## Petrol already in a diesel around Sturton by Stow?

Why? A fair single quote does not exist here: four situations, four separate tasks. Which of them you are in is chiefly what shifts the cost. The proportion counts next, meaning how much of the tank is petrol, followed by the position of your car and whether getting to it is safe for a technician. That's why our technicians ask three questions before quoting rather than after: what went in, how much, and if it has run. Those answers change a range into a straight figure. ## About Sturton by Stow Sturton by Stow is a village in Lincolnshire, situated near the city of Lincoln and the village of Stow.
