Less than you likely are, provided it has not been started. Everyone around Scotts Green begins with "have I wrecked it?", and the honest answer is normally no: petrol left in your tank of a diesel stays harmless till priming, cranking or driving draws it into the system. Keep it that way: leave your engine off and call Petrol in Diesel. Keep reading for three things: the effect petrol has inside a diesel engine, the clues of how far it has spread, and ways to make sure you don't do it again. ## What petrol in a diesel does to the motor Diesel has two jobs on its way through a motor. Before it burns, it lubricates — and then it ignites. Your high-pressure pump and your injectors are made to extremely fine tolerances, and the diesel passing through them is what stops those surfaces from grinding against one another. Petrol does the first job badly and the second not at all. A pump running on a petrol mixture is wearing itself out, since petrol is runnier than diesel and strips out the lubrication your fuel system relies on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that is where any clattering comes. The shape of the trouble is clear once you put those together. It's movement that does the harm, not contact. Petrol in the tank is a fuel issue. Once your pump has been running on that petrol, a mechanical issue has begun: whatever is shed by a pump that is grinding travels downstream to your injectors with your fuel. ## Scotts Green, petrol in a diesel: four cases, from mild to major Filled but not once started — as good as it gets. On a forecourt, and truly only there, the petrol is still limited to your tank — since anywhere else the vehicle was driven to get to it. The job is emptying and flushing on the spot. A moment's running, or just the ignition on. With your system primed, the lines and filter already hold petrol that has come from the tank. Drain, flush, deal with the fuel filter: still usually simple. Your pump has worked a few miles on weakened fuel — that's what driving the vehicle meant. How hard the car was driven counts as much as how far, and this work takes in that tank, the fuel lines, the fuel filter and fresh fuel through the entire system. Driving the children to Blowers Green Primary School is one sort of trip. Very different a second time: a run to Wolverhampton, under 10 miles away, or any mileage on the M5, under 5 miles from Scotts Green, where the engine never stopped running hard. It complained, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone ragged. What you are hearing is your motor signalling fuel that no longer behaves like diesel. Whether it is the verge on Clee Road, a lay-by or a side road, stop where you are and leave it. The drain and flush-through still go first, and they deal with it: when a vehicle is stopped soon, lasting damage is very rare. ## Scotts Green motorists and that petrol in a diesel myths they hear Myth: topping up to full with diesel makes it fine. It does not. A fuller tank of the same mix is all you get, because topping up removes nothing. The assumption behind the advice — that diesel fuel systems tolerate petrol by percentage — is wrong. Myth: a modern diesel copes with a bit of petrol. Rather, the reverse. A current diesel runs its fuel through finer components at higher pressure, which makes the protection matter more, not less. This is the one that catches drivers. Myth: "If it starts and drives, there is no harm done." The driver of a petrol engine fed diesel normally has no choice but to stop, because it will not run, and the harm stops there. Whilst your pump wears, a diesel fed petrol usually starts, idles and drives away as though nothing has happened. Running is not the same as fine. Myth: "Add some two-stroke oil and drive it home." It is an old workaround for a different problem. It doesn't put back what petrol has weakened, and the petrol is still in the tank after that. The next start sends petrol back round the pump from the fuel lines and your filter, where some of that sits after the engine has run. That's why draining the tank yourself does not sort it — a myth. It is also truly hazardous to drain petrol into a can at the kerbside. ## Why petrol in a diesel happens so easily It's seldom carelessness, and no one does it on purpose. The forecourt makes it easy: the petrol nozzle is the narrower of the two, and it slides into a diesel filler with almost no resistance, whilst a diesel nozzle mostly will not go into a petrol car at all. So the mistake runs one way. The moment routine stops matching the car is the moment it takes place. A vehicle that's new to you — hired, on loan as a courtesy car, or brand new. Households running one of each, petrol and diesel. The pumps in a different order on a familiar forecourt. Racing for a train at Cradley Heath and filling up en route. A new-to-you diesel Renault Megane, its first fuelling, and a driver used to petrol: precisely when it occurs. Your hand does what it has always done when you add rain, a phone call or a back seat full of children. ## Next time you fill up in Scotts Green: preventing petrol in a diesel - The label is what counts, so check the petrol pump rather than the colour: in the UK unleaded handles are normally green and diesel black, but not on every forecourt. - Plenty of cars state the fuel inside your filler flap or on the cap, and so check there on your first fill in any car you don't know. - Good intentions count for less than a sticker or a fob in a vivid colour on your diesel's key when a household has one of each. So label it. - Say it before you lift it. On the 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 works. - Put the phone away. This is an easy mistake to make while you're thinking about something else. - Add-on devices are available for motors without one, and some diesels are built with a filler that won't accept a petrol nozzle. Useful — but a safety net only, never a reason to stop checking the label. - Spotting it mid-fill? Stop at once. A thinner mixture results from less petrol inside that tank, yet the next step remains the same: don't fire it up. ## Put petrol in a diesel in Scotts Green already? Short and simple, then, is the order of things. Do not turn your ignition on, and do not crank it. Still at the forecourt, at Texaco or anywhere else? Ask the attendants to help you roll the car clear of the pump. Phone 0333 366 0103 next, with three answers — the fuel, the rough volume, and whether it's run. Corrosion and deposits form the problem with AdBlue, where petrol means lost protection. So if it was AdBlue, say so — and see its own Scotts Green page. ## What makes one Scotts Green petrol in a diesel task cost more than the next There's no honest single price for this, because the four situations above are four separate tasks. The scenario itself does most of the work of moving your cost. Where the car is counts too, and whether our van can safely reach it, after the ratio of petrol to what that tank holds. Before any quote, not after, we ask three queries: your fuel that got in, its volume, and whether it's run. That is why. Those replies turn a range into a straight figure. ## About Scotts Green itself Scotts Green is a suburban area located on the outskirts of Wolverhampton, near the riverside and surrounded by other local neighbourhoods such as Springs Mire and Blowers Green.
