Petrol in a Diesel Car in Abbey Field Likely less than you already are — provided no one has started the car. "Have I ruined it?" is the first thing everyone in Abbey Field asks, and the truthful answer is generally no, since petrol left in a diesel tank harms nothing until it's drawn through the system — by ignition priming, by the starter, or by driving. Keep it like that: leave the motor off and ring Petrol in Diesel. What petrol really does to a diesel, how to judge how far it's travelled, and how to stop it from happening again: that's the rest of this page. ## What petrol in a diesel does to the motor Passing through an engine, diesel does two jobs at once. It protects to begin with, and after that does it burn. What stops the surfaces inside the high-pressure fuel pump and the injectors from wearing down against each other is your diesel passing through them — they are designed to very fine tolerances. The second job petrol does not do at all, and the first it does poorly. The knocking comes from petrol being made not to ignite when compressed, which is exactly the reverse of what a diesel needs. On top of that it is thinner than diesel, it strips away the protection your system hinges on, and any pump running on that blend is wearing itself. The shape of the trouble is clear when you put those together. It's circulation that causes 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 further on. ## Abbey Field, petrol in a diesel: four cases, from mild to serious Filled but not once started — as good as it gets. Only that tank has petrol in it, so the task is draining the tank and flushing the system where your car stands. This situation can only really occur on a forecourt: anywhere else, the vehicle got there by being driven. A moment's running, or merely the ignition on. Petrol has left that tank and got to the filter and the lines, because your system has been bled. Still normally straightforward: drain, flush, and the filter sorted. A couple of miles driven, and the pump has spent every one of them working on diluted fuel. The work is the tank, the lines, the filter and fresh fuel through the entire system, and how hard the car was driven matters as much as how far. On the school run to St John's Green Primary School, the distance is small. Any miles on the M11, under 50 miles from Abbey Field, means the engine has worked hard throughout, and a run to Colchester, under a mile away, makes a very different job too. Driven on till it protested — rattling, smoke, an uneven idle, a soft throttle. The fuel is not acting like diesel any more, and the engine is telling you. Leave it wherever it stops: a lay-by, a side street, the verge on Roman Circus Walk. Long-term damage is very rare if a vehicle is pulled over quickly, and the drain and flush-through that still come first take care of it. ## Stories Abbey Field motorists hear about petrol in a diesel It will not be fine. The myth: "Fill it the rest of the way with diesel and it'll be." Nothing is removed by topping up — you're left with a fuller tank, still the same mix. The assumption behind the advice — that diesel fuel systems tolerate petrol by percentage — is wrong. Myth: "A modern diesel can cope with a bit of petrol." If anything, the opposite. A newer diesel sends its fuel through smaller parts at higher pressure, which makes the lubrication count more, not less. This is the one that fools drivers. Myth: "If it starts and drives, there is no damage done." Diesel in a petrol motor generally means a motor that will not run: the motorist stops, and so does the damage. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually will; meanwhile the pump wears. Being able to run isn't the same as being fine. An old workaround for a separate problem is behind this one. Myth: "Add some two-stroke oil and drive the vehicle home." The petrol is still inside that tank after that, and whatever it has diluted is not put back. "Drain it yourself and you're sorted" — a myth, because after it's been running some petrol sits in the filter and lines, waiting to go right back through the pump on the next start. It is also truly risky to drain petrol into a can by the roadside. ## How does petrol in a diesel happen? On purpose? Never. Through carelessness? Seldom, if ever. The forecourt makes it simple: the petrol nozzle is the smaller of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol vehicle at all. So the mistake runs one way. The moment routine stops matching your car is the moment it occurs. A new motor, a hire car or a courtesy car. A household with one petrol and one diesel on the drive. A well-known forecourt with the pumps in a different order. A train to catch, and a rushed fill on the way to Colchester Town. A new-to-you diesel Volkswagen Golf, its first fuelling, and a driver accustomed to petrol: exactly when it takes place. Your hand does what it has always done when you add rain, a phone call or a back seat full of kids. ## Abbey Field drivers: how to avoid petrol in a diesel next time - The label is what matters, and so read the pump rather than the colour: in the UK unleaded handles are normally green and diesel black, yet not on every forecourt. - Many cars state the fuel type inside your filler flap or on the cap, and so check it on your first fill in any car you do not know. - One of each in the home? Label your key to the diesel — a coloured fob, a sticker — since intending to remember isn't enough. - Say it before you lift it. On the 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. - Mistakes like this are easy to make whilst your mind is on something else, and so the phone goes away. - Up to a point, a misfuel inhibitor helps: some diesels have a filler designed to reject a petrol nozzle, and add-on devices are available for the remainder. Count it as a safety net, and keep checking the petrol pump. - Less petrol means a weaker blend, so stop as soon as you realise — while remembering that the next stage is unchanged. It's still not to fire it up. ## Put petrol in a diesel around Abbey Field already? Short and simple, then, is the order of things. Do not crank it, and do not turn the ignition on. The attendants at the forecourt — whether at Texaco itself or wherever you filled up — will usually help push it away from the pump if you ask. Next, 0333 366 0103. We will ask what was put in, roughly how much, and if it's been run. AdBlue, not petrol? Then say so. Corrosion and deposits, not lost protection, make it a separate issue — Abbey Field has a page just for it. ## What makes one Abbey Field petrol in a diesel task cost more than the next The four scenarios above are four different tasks, so no single quote for this would be fair. What moves your cost is chiefly which of them you're in. Next it's the proportion — how much petrol was put in against how much the tank holds — and after that where your car is and whether a van can reach it safely. That's why we ask three queries before quoting rather than after: what went in, how much, and whether it has run. Given the answers, there is a straight figure rather than a range. ## About Abbey Field and where it is Abbey Field is a locality situated near the city of Colchester in Essex, lying at an elevation of 38 metres above sea level.
