Petrol in a Diesel Car in Meopham Far less than you probably are, if it has not been started. "Have I ruined it?" is the first question anyone in Meopham asks, and the truthful answer is generally no, since petrol left in a diesel tank harms nothing till it is drawn through the fuel system — by ignition priming, by your starter, or by being driven. Keep it that way: leave your engine off and ring Petrol in Diesel. Read on for three things: the effect petrol has inside a diesel motor, the clues of how far it has got, and the way to make sure you don't repeat it. ## Inside the motor: what petrol in a diesel does Two tasks 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 wearing against each other is the diesel flowing through them — they're built to very fine tolerances. The second task petrol doesn't do at all, and the first it does badly. It is runnier than diesel and strips away the lubrication the system depends on, and so a pump running on a petrol mix is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That's where the knocking comes from. The shape of the trouble is clear once you put those together. Contact doesn't do the harm — circulation does. All a tank with petrol in it amounts to is a fuel fault. 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 your fuel to the injectors further on. ## How serious is petrol in a diesel? Four scenarios our engineers see in Meopham The best case there can be: filled up, never started. The petrol is in that tank and only your tank, and the task is a drain and a flush where the car stands. This is the one scenario that can only truly take place at a forecourt, as anywhere else the car has been driven to get there. A brief spell of running, or just your ignition on. With your system primed, the fuel lines and filter already hold petrol that has come from the tank. Drain, flush, deal with the fuel filter: still usually easy. Those few miles on the road were the pump working on fuel thinned by petrol throughout. How hard your car was driven matters as much as how far, and this work takes in that tank, your lines, the filter and fresh fuel through the whole system. Driving the children to Meopham Community Academy is one sort of trip. A run as far as Southend-on-Sea, under 25 miles away, is a very different task. So is any distance on the M2, under 5 miles from Meopham, where your engine has been working hard throughout. It complained, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone ragged. That's your engine telling you its fuel has stopped behaving like diesel. Whether it is the verge on Meadfield Road, a lay-by or a side road, stop there then leave it. A car stopped soon very seldom has permanent damage, as the fuel drain and the flush-through, which still go first, take care of it. ## Stories Meopham drivers hear about petrol in a diesel Myth: topping up to full with diesel makes it fine. It does not. Topping up removes nothing; it gives you a fuller tank of the same mix. Percentage is not how a diesel fuel system tolerates petrol, whatever that advice assumes. Not so: a newer diesel copes with a bit of petrol. If anything, the reverse. Protection counts more on newer diesels, not less, since their fuel passes through finer parts at higher pressure. The myth that catches motorists off guard: if it starts and drives, it must be unharmed. Diesel in a petrol motor generally means a motor that won't run: the driver stops, and so does the harm. Feed petrol to a diesel and it usually fires up, ticks over and pulls away as if nothing has happened — all while its pump wears. Running isn't the same as fine. "A drop of two-stroke oil and drive it home" — a myth, taken from a fix from years ago, for a distinct issue. It does not put back what petrol has diluted, and the petrol is still inside that tank after that. Myth: "Drain the tank yourself and you're sorted." Once the engine has been run, some of the petrol is no longer in that tank: it is in the filter and the fuel lines, and it goes straight back through the pump on your next start. It's also really hazardous to drain petrol into a can at the kerbside. ## How does petrol in a diesel occur? Carelessness is rarely the cause, and no one means to do it. The petrol nozzle is the narrower of the two and slides into a diesel filler with almost no resistance; a diesel nozzle mostly won't go into a petrol motor at all. The forecourt makes it simple, and the error runs one way. Routine and your car getting out of step is when it takes place. Hire cars, courtesy cars, and motors that are new to you. Households running one of each, petrol and diesel. A forecourt you know, but with its pumps arranged differently. A rushed fill on the way to the nearest station with a train to catch. Exactly the moment it happens: after years of driving petrol, a driver fills a diesel Renault Clio for the first time. The hand does what it has always done when you add rain, a phone call or a back seat full of children. ## Preventing petrol in a diesel next time you fill up around Meopham - Read the pump, not the colour. In the UK unleaded handles are generally green and diesel black, but not on each forecourt. The label is what counts. - The first fill in an unfamiliar vehicle is the time to check the filler flap — on it, or on the cap, plenty of motors state the fuel to use. - A coloured fob or a sticker on your diesel's key achieves more than any amount of meaning to remember, for a house with one of each. - Say it before you lift it. On your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the pump. It seems daft and it does the trick. - Put your phone away. This is an easy mistake to make whilst you are thinking about something else. - A misfuel inhibitor helps, up to a point. Some diesels have a filler built to reject a petrol nozzle, and add-on devices exist for cars without one. They are a safety net, not a reason to stop checking the pump. - Stop the moment you realise. Less petrol in the tank makes a thinner blend. It does not change what to do next, which is still not to start it. ## Petrol already in a diesel around Meopham? Start here The order of things is brief, then. Don't turn the ignition on, and do not start it. The staff on the forecourt — whether at Texaco itself or wherever you filled up — will usually help roll it away from the pump if you ask. Next, 0333 366 0103. We'll ask what got in, roughly how much, and if it has been run. Corrosion and deposits form the issue with AdBlue, whereas petrol brings lost protection. So if it was AdBlue, say so — and read its own Meopham page. ## What makes one Meopham petrol in a diesel job cost more than the next The four scenarios above are four different jobs, so no single quote for this would be fair. Which of them you are in is chiefly what moves the cost. Two things follow that: the petrol that was put in as a share of what the tank holds, then the spot the car is in and whether a van can get to it safely. That's why our engineers ask three queries before costing rather than after: what went in, how much, and whether it has run. With those answers, you get a straight figure instead of a range. ## About Meopham itself Meopham is a village in Kent, situated inland at an elevation of around 133 metres, and is characterized by its predominantly detached housing stock.
