How Worried to Be Not started? Then less worried than you probably feel. Until the ignition primes your pump, your starter turns, or your car is driven, petrol in a diesel tank simply rests there and does no harm. Which means the truthful reply to that first Hove query — "have I wrecked it?" — usually no. Petrol in Diesel is who to phone, with your engine kept off, and so it remains that way. What petrol really does to a diesel, how to gauge how far it's gone, and how to stop it from happening again: that's the rest of this page. ## Petrol in a diesel: what does it do to the motor? Two tasks fall to diesel on its route through a motor. Before it combusts, it protects — then it combusts. What keeps the surfaces inside your high-pressure pump and your injectors from grinding against one another is your diesel passing through them — they're made to very fine clearances. Petrol does the first job badly and the second not at all. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, leaving a pump on the mixture wearing itself. It is also made to resist igniting under compression — the reverse of what a diesel needs — which is why you hear the clattering. Put those together and the shape of the issue is plain. It's circulation that does the harm, not contact. Any tank with petrol in it is a fuel issue. Once the pump has been running on that petrol, a mechanical issue has begun: anything shed by a pump that's wearing down is carried onward to the fuel injectors with your fuel. ## Hove, petrol in a diesel: four situations, from mild to significant Fuelled but not once started — as good as it gets. That petrol is inside the tank and only that tank, and the task is a drain and a flush where the car stands. This is the one situation that can only truly occur on a forecourt, since anywhere else the vehicle has been driven to get there. A moment's running, or merely your ignition on. The fuel system has been bled, and so petrol has left the tank and reached the fuel filter and the lines. Still normally straightforward: drain, flush, and the fuel filter sorted. Some miles driven, and your pump has spent each of them labouring on diluted fuel. Mileage is only half of that; how hard it was driven counts equally. Either way the work includes the tank, your lines, the filter and fresh fuel through the entire circuit. Driving the kids to St Andrew's CofE (Aided) Primary School is one kind of trip. Any miles on the M23, under 25 miles from Hove, means the engine has worked hard throughout, and a run to Brighton and Hove, under 3 miles away, makes a very different job as well. Driven on till it complained — knocking, smoke, a lumpy idle, a soft throttle. The engine is telling you your fuel is no longer behaving like diesel. Pull up wherever you are — the verge on Church Road, a lay-by, a side street — and leave the car there. What comes first is still the drain and flush, and that sorts it out, with permanent damage very unusual when a car is stopped soon. ## What Hove people get told about petrol in a diesel — and the stories in it "Top it up the rest of the way with diesel and it'll be fine" — a myth. It will not. Topping up takes out nothing; it gives you a bigger tank of the same mixture. The idea behind that advice — that diesel fuel systems accept petrol by percentage — is wrong. "Newer diesels can handle a little petrol" — a myth, and closer to the reverse. Finer components and higher pressure are how a modern diesel runs its fuel, and that makes the protection matter more, not less. This is the one that catches drivers. Myth: "If it starts and drives, there's no damage done." Feed diesel to a petrol motor and it generally will not run, and so the driver stops — and the damage stops with them. A diesel fed petrol normally starts, ticks over and drives away as if nothing has happened, while the pump wears. Fine and running aren't the same at all. "A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a separate problem. The petrol is still inside the tank afterwards, and whatever it has thinned isn't put back. "Drain it yourself and you are sorted" — a myth, because after it has been running some petrol lies in the fuel filter and lines, waiting to go right back through the pump at your next start. Draining petrol into a can at the roadside is also genuinely hazardous. ## Petrol in a diesel: how does it occur? No one does it on purpose, and it's rarely carelessness. A diesel nozzle mostly will not go into a petrol car, yet the narrower petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake easy, and just in that direction. When habit and your car stop matching, it occurs. A motor that's new to you — hired, on loan as a courtesy car, or just bought. Two cars on one drive, one petrol, one diesel. A well-known forecourt with the pumps in a different order. A rushed fill on the way to the nearest station with a train to catch. Years of petrol vehicles behind you, a diesel Renault Clio in front of you on the forecourt for its first tank — that's when. Throw in a back seat full of kids, a phone call or rain, and the hand takes over. ## Hove drivers: how to avoid petrol in a diesel next time - Read the pump, not the colour. In the UK unleaded handles are normally green and diesel black, but not on each forecourt. The label is what matters. - Plenty of vehicles state the fuel inside the filler flap or on the cap, so check it on your first fill in any vehicle you don't know. - Label your key. In a home with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember. - Before the nozzle comes off the petrol pump the first time you fuel a hired or new car, say "diesel" aloud. Daft, perhaps, but it works. - Put your phone away. This is an easy mistake to make whilst you are 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 are available for the remainder. Count it as a safety net, then keep reading the pump. - Noticing it halfway? Stop there and then. A weaker mix follows from less petrol in the tank, yet your next step remains the same: don't crank it. ## Hove: already put petrol in a diesel? Short and simple, then, is the order of things. Do not switch the ignition on, and don't start it. The staff on the forecourt — whether at Esso itself or wherever you filled up — will usually help push it away from the pump if you ask. What got in, about how much, and if it has run: tell us that when you ring 0333 366 0103. If it was AdBlue and not petrol, say so. That is a separate fault — corrosion and deposits and not lost lubrication — and it has its own page for Hove. ## Hove petrol in a diesel tasks: why one costs more than another A fair single quote doesn't exist here: four situations, four separate tasks. What moves the cost is chiefly which of them you're in. The ratio counts next, meaning how much of the tank is petrol, followed by the location of the car and whether reaching it is safe for a van. What was put in, how much, and if it has run — three questions our technicians ask before quoting, not after, for exactly that reason. A range becomes a straight figure once those answers are in. ## About Hove, for a moment Hove is a coastal locality in East Sussex, situated approximately 1.2 miles west of Brighton city centre.
