Petrol in a Diesel Car in Barton Stacey If it hasn't been started, worry less than you probably are. Till your ignition primes your pump, the starter turns, or the vehicle is driven, petrol in a diesel tank just rests there and does no harm. Which means the truthful reply to that first Barton Stacey query — "have I wrecked it?" — normally no. Keep it like that: leave your motor off and ring Petrol in Diesel. The remainder of this page sets out what petrol really does to a diesel, how to tell how far it has got, and how to make sure it does not happen to you again. ## The motor and petrol in a diesel: what goes on Two jobs fall to diesel on its route round a motor. Before it burns, it lubricates — and then it ignites. Extremely fine tolerances are built into your injectors and your high-pressure pump, and only the diesel flowing through keeps their surfaces from grinding together. Petrol handles the first job badly and the second not at all. Being less viscous than diesel, petrol strips out the protection a fuel system needs, so a pump running on the mixture wearing itself. It's also made to resist igniting under compression — the opposite of what a diesel needs — which is why you get the clattering. Put these together and the shape of the trouble is plain. It's circulation that causes the harm, not contact. A tank with petrol in it is a fuel problem. The start of a mechanical problem is a pump that has been working on that petrol — and whatever a worn pump sheds moves on with the fuel to your injectors beyond it. ## Barton Stacey, petrol in a diesel: four situations, from mild to serious Filled up, and never started: nothing beats it. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With that petrol kept in that tank alone, it's emptied and rinsed on the spot, and nothing more is needed. Ignition on, or started for a second. With the system primed, the lines and filter now contain petrol that has come from your tank. Usually nothing more than draining, rinsing and sorting the filter, and so still easy. Those few miles driven were your pump labouring on fuel thinned by petrol the whole way. Tank, lines, filter, then clean fuel run through the entire system: that is the work, and the way the vehicle was driven counts as much as the miles. On the school run to Barton Stacey Church of England Primary School, the distance is short. Any miles on the M3, under 10 miles from Barton Stacey, means the motor working hard throughout, and a run to Winchester, under 10 miles away, makes a very different job as well. Driven till it complained. Clattering, a lumpy idle, smoke, a throttle that has gone soft. That is your engine telling you its fuel no longer is behaving like diesel. Leave it wherever it has stopped: a lay-by, a side street, the verge on Newton Lane. What goes first is still the drain and flush-through, and that sorts it out, with long-term damage very rare if a car is stopped quickly. ## Myths Barton Stacey people hear about petrol in a diesel Myth: "Fill it the rest of the way with diesel and it will be fine." It will not. A fuller tank of the same mix is all it gives, since topping up takes out nothing. That guidance presumes a diesel fuel system handles petrol by percentage. It does not. Myth: "A current diesel can cope with a bit of petrol." If anything, the reverse. At higher pressure, through finer parts: that's how a modern diesel moves its fuel, and so the lubrication matters more, not less. This is the one that fools drivers. Myth: "If it starts and drives, there's no harm done." A petrol engine fed diesel normally won't run, so the driver stops and the damage stops with them. Whilst the pump wears, a diesel fed petrol normally starts, idles and drives away as if nothing has happened. Fine and running are not the same thing. An old workaround for a distinct fault is behind this one. Myth: "Add some two-stroke oil and drive it home." None of what petrol diluted gets put back by it — and later, that tank still contains that petrol. "Drain it yourself and you are sorted" — a myth, since after it's been running some petrol sits in the fuel filter and lines, waiting to go straight back through your pump at your next start. Also, a can of petrol filled at the kerbside is genuinely risky. ## How petrol ends up: petrol in a diesel A careless moment 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 will not go into a petrol car at all. The forecourt makes it easy, and the slip runs one way. When routine and the vehicle stop matching, it takes place. Any vehicle that is new to you — hired, on loan as a courtesy car, or brand new. Two vehicles on one drive, one petrol, one diesel. A forecourt you know, but with its pumps laid out differently. A rushed fill en route to Whitchurch (Hampshire) with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a motorist accustomed to petrol: exactly when it takes place. With rain, a call coming in, or children to deal with, the hand just does what it always has. ## Avoiding petrol in a diesel next time you fill up around Barton Stacey - The label is what counts, so check the pump rather than the colour: in the UK unleaded handles are usually green and diesel black, yet not on every forecourt. - Check the filler flap. Plenty of vehicles state the fuel type inside the flap or on the cap. Look at it on the first fill in a motor you don't know. - Good intentions do less than a sticker or a fob in a vivid colour on the diesel's key if a household has one of each. So mark it. - Before the nozzle leaves the pump the first time you fuel a hired or new motor, say "diesel" aloud. Daft, perhaps, yet it does the trick. - Tuck the phone away. This is an easy mistake to make whilst you are thinking about something else. - Some diesels come with a filler built to reject a petrol nozzle, and devices you can add exist for motors without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the petrol pump. - Spotting it mid-fill? Stop at once. A weaker mixture results from less petrol in the tank, yet the next stage stays the same: do not start it. ## Petrol already in a diesel in Barton Stacey? Begin here Short and simple, then, is the order of things. Don't turn your ignition on, and do not fire it up. Ask the staff to help you push it clear of the pump if you're still at the forecourt, whether that's Esso or somewhere else. Next, 0333 366 0103. We'll ask what was put in, about how much, and if it has been run. Corrosion and deposits are the problem with AdBlue, whereas petrol brings lost lubrication. So if it was AdBlue, say so — and read its own Barton Stacey page. ## Why one petrol in a diesel task in Barton Stacey costs more than another Four different tasks lie behind the four scenarios above — which is why there's no fair single quote. What moves the cost is chiefly which of them you're in. Beyond that it's the ratio — how much petrol got in against how much your tank holds — and after that where the car is and whether a van can get to it safely. What got in, how much, and whether it has run — three queries our engineers ask before pricing, not after, for exactly that reason. A range turns into a straight figure when the answers are in. ## About Barton Stacey Barton Stacey is a village in Hampshire, situated on the banks of the River Test at an elevation of around 61 metres.

Our engineers drain wherever the vehicle is — your own driveway, a lay-by, a supermarket car park, a forecourt — so it does not have to come to us. ## Barton Stacey: still at the petrol pump? The best spot there is, then — that is where you are. Turned off it remains; then phone.
