Petrol in a Diesel Car in Etruria Less than you likely are, if it hasn't been started. Everyone in Etruria begins with "have I wrecked it?", and the honest answer is normally no: petrol resting in the tank of any diesel remains harmless till priming, cranking or driving draws it into the fuel system. Leave the engine off and phone Petrol in Diesel — that is how you keep it like that. The remainder of this page explains what petrol really does to a diesel, how to tell how far it has got, and how to make sure it doesn't happen to you again. ## The motor and petrol in a diesel: what happens Two jobs fall to diesel on its journey through a motor. It lubricates to begin with, and after that does it burn. What keeps the surfaces inside the high-pressure fuel pump and your injectors from grinding against one another is the diesel flowing through them — they are designed to very fine gaps. Of those two tasks, petrol manages the first badly and the second not at all. A pump working on a petrol mixture is wearing itself out, since petrol is runnier than diesel and takes away the lubrication your fuel system depends on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel needs from its fuel — and that's where any knocking comes. Seen together, they show what shape the issue takes. Contact does not do the damage — movement does. Where that petrol is only in the tank, it is a problem of fuel, nothing more. A pump that has been working on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with the fuel to your injectors further on. ## Four scenarios our engineers see around Etruria: how serious is petrol in a diesel? The best case there can be: filled up, never started. Being at a forecourt is what makes this possible: elsewhere, your car has been driven there to begin with. With that petrol held inside the tank alone, it is cleared and purged on the spot, and nothing more is needed. Ignition on, or started for a moment. Petrol has left that tank and reached the fuel filter and your lines, because the system has been primed. That's usually still a simple job — a drain, a flush, and the filter seen to. Driven a few miles. Now the pump has spent these miles running on thinned fuel. The work is your tank, the fuel lines, the filter and clean fuel through the whole circuit, and how hard your car was driven counts as much as how far. On the school run to Etruscan Primary School, the distance is small. A run as far as Stoke-on-Trent, under a mile away, is a very different task. So is any distance on the M6, under 5 miles from Etruria, where your engine has been running hard throughout. Rattling, a lumpy idle, smoke, a throttle gone soft: driven until it complained. The engine is telling you the fuel is no longer acting like diesel. Whether it is the verge on Ladysmith Road, a lay-by or a side street, stop where you are and leave it. The fuel drain and flush-through still come first, and they take care of it: if a car is stopped early, lasting damage is very unusual. ## Myths Etruria drivers hear about petrol in a diesel Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Nothing comes out when you top up — that tank just carries more of the same mixture. That guidance assumes a diesel fuel system handles petrol by percentage. It does not. Myth: a current diesel copes with a bit of petrol. If anything, the reverse. A newer diesel sends its fuel through more precise components at higher pressure, which makes the protection matter more, not less. "It starts, it drives, so no harm done" — the myth that trips up most drivers than any other. Diesel in a petrol motor normally means a motor that will not run: the driver stops, and so does the damage. A diesel fed petrol usually starts, ticks over and drives away as though nothing has happened, whilst the pump wears. Running isn't the same as fine. An outdated workaround for a different problem lies behind this one. Myth: "Add some two-stroke oil and drive the vehicle home." The petrol is still inside the tank after that, and what it has thinned isn't put back. "Drain it yourself and you are sorted" — a myth, since after it has been running some petrol lies in your filter and lines, ready to go straight back through your pump at the next start. Besides, petrol emptied into a can by the road is genuinely risky. ## How it happens: petrol in a diesel Nobody does it on purpose, and it is seldom carelessness. A diesel nozzle mostly will not go into a petrol motor, but the narrower petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake simple, and only in one direction. The moment routine stops matching the vehicle is the moment it occurs. A new vehicle, a hire car or a courtesy car. One petrol and one diesel on the driveway of the same household. A forecourt you know, but with its pumps laid out differently. Filling up in a rush en route to Stoke-On-Trent, with a train to catch. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is precisely the moment it takes place. Add rain, a phone call or a back seat full of kids, and your hand repeats what it has always done. ## Next time you fill up around Etruria: preventing petrol in a diesel - The label is what counts, so check the pump instead of the colour: in the UK unleaded handles are usually green and diesel black, yet not on every forecourt. - Inspect the filler flap. Plenty of motors state the fuel inside the flap or on the cap. Look at it on the first fill in a car you don't know. - A coloured fob or a sticker on the diesel's key does more than any amount of intending to remember, in a household with one of each. - It seems silly and it works: on your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the pump. - Thinking about something else is when this becomes an easy mistake to make, and so put your phone away then keep your mind on the pump. - Add-on devices are available for motors without one, and some diesels come with a filler that won't take a petrol nozzle. Useful — but a safety net at best, never a reason to stop checking the label. - As soon as you realise, stop: less petrol inside your tank makes a thinner mixture. What to do next does not change, though — still don't crank it. ## Etruria: already put petrol in a diesel? Then, there is just a short order of things. Don't fire it up, and don't turn the ignition on. Ask the staff to help you roll it clear of the pump if you are still on the forecourt, whether that's Tesco or anywhere else. Ring 0333 366 0103 next, with three facts — the fuel, the rough amount, and if it's run. AdBlue, not petrol? Then say so. Corrosion and deposits, not lost protection, make it a different problem — Etruria has a page just for it. ## Etruria petrol in a diesel tasks: why one costs more than another An honest single quote doesn't exist here: four situations, four separate tasks. Mostly, the cost shifts with which situation you are in. The proportion counts next, meaning how much of your tank is petrol, followed by the position of the car and whether getting to it is safe for a van. That is why we ask three questions before costing rather than after: what went in, how much, and whether it's run. Those answers turn a range into a straight figure. ## About Etruria, for a moment Etruria is a suburban area located on the outskirts of Stoke-on-Trent in Staffordshire, situated near the River Trent at an elevation of around 129 metres.
