Petrol in a Diesel Car in Outwood Gate If it hasn't been started, you can worry less than you probably are. Everyone in Outwood Gate starts with "have I wrecked it?", and the fair answer is generally no: petrol resting inside your tank of a diesel remains harmless till priming, cranking or driving draws it into your fuel system. Leave your engine off then call Petrol in Diesel — that is how you keep it like that. The remainder of this page covers what petrol really does to a diesel, how to judge how far it has got, and how to make sure it doesn't happen to you a second time. ## The engine and petrol in a diesel: what happens Passing through a motor, diesel is doing two things at the same time. Before it ignites, it lubricates — then it combusts. What stops the surfaces inside the high-pressure pump and your injectors from wearing against each other is the diesel passing through them — they're made to extremely fine gaps. The second task petrol doesn't do at all, and the first it does poorly. The knocking comes from petrol being designed not to ignite when compressed, which is precisely the opposite of what a diesel needs. On top of that it is thinner than diesel, it strips away the protection the fuel system hinges on, and any pump running on such a mixture is wearing itself. The shape of the issue is clear when you put those together. Not contact but movement is what does the damage. A tank with petrol in it is a fuel issue. A pump that has been running on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with the fuel to the injectors downstream. ## How bad is petrol in a diesel? Four scenarios our technicians see around Outwood Gate Filled up, and never started: nothing beats it. Being at a forecourt is what makes this the case: elsewhere, the car has been driven there to begin with. With the petrol kept inside that tank alone, it's drained and cleaned right where it stands, and nothing more is needed. Your ignition switched on, or a brief start. With the system primed, the fuel lines and filter already hold petrol that came from the tank. That is generally still an easy job — a drain, a flush, and your filter dealt with. Driven a couple of miles. Now your pump has spent these miles running on weakened fuel. How hard the car was driven counts as much as how far, and this work takes in your tank, the fuel lines, your filter and clean fuel through the whole circuit. Driving the children to St John's Church of England Primary School, Radcliffe is one kind of trip. Any miles on the M60, under 3 miles from Outwood Gate, means the motor working hard throughout, and a run to Salford, under 5 miles away, makes a very different job as well. Knocking, an uneven idle, smoke, a throttle gone soft: driven till it complained. The fuel isn't acting like diesel any more, and your motor is saying so. Whether it is the verge on Wood Green Drive, a lay-by or a side road, stop there and leave it. A car stopped early very seldom has lasting damage, because the drain and the flush, which still come first, sort it out. ## Outwood Gate drivers and that petrol in a diesel stories they hear "Top it up the rest of the way with diesel and it will be fine" — a myth. It won't. Topping up removes nothing; it gives you a bigger tank of the same mixture. The idea behind that guidance — that diesel fuel systems tolerate petrol by percentage — is wrong. "Current diesels can handle a little petrol" — a myth, and closer to the reverse. A current diesel runs its fuel through smaller components at higher pressure, which makes the protection matter more, not less. One myth that catches people out: if it starts and drives, it must be unharmed. Feed diesel to a petrol engine and it generally won't run, and so the motorist stops — and the damage stops with them. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually will; meanwhile your pump wears. Fine and running aren't the same at all. Myth: "Add some two-stroke oil and drive the car home." It's an old fix for a distinct problem. It doesn't put back what petrol has thinned, and that petrol is still in that tank after that. Myth: "Drain that tank yourself and you are sorted." Once your engine has run, some of that petrol is no longer inside your tank: it's in the filter and the lines, and it goes straight back through the pump at your next start. Besides, petrol emptied into a can by the road is truly hazardous. ## How petrol ends up: petrol in a diesel It's seldom carelessness, and no one does it on purpose. One way only, since of the nozzles: the smaller petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one mostly won't fit a petrol car. That's how the forecourt makes it straightforward. Routine and the car falling out of step is how it occurs. Hire cars, courtesy cars, and vehicles that are new to you. Households running one of each, petrol and diesel. A forecourt you know, only with its pumps arranged differently. A hurried fill en route to Clifton with a train to catch. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is exactly the moment it happens. The hand repeats what it has always done when you add rain, a phone call or a back seat full of kids. ## Avoiding petrol in a diesel next time you fill up in Outwood Gate - The label is what counts, so check the pump rather than the colour: in the UK unleaded handles are normally green and diesel black, but not on every forecourt. - The first fill in an unfamiliar car is the time to check your filler flap — inside it, or on the cap, plenty of cars state the fuel to use. - A coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember, for a house with one of each. - Before the nozzle comes off the petrol pump the first time you fuel a hired or new car, say "diesel" out loud. Silly, perhaps, yet it works. - Thinking about something else is when this becomes an easy mistake to make, so tuck the phone away then keep your mind on the pump. - Some diesels come with a filler designed to reject a petrol nozzle, and devices you can add are available for vehicles without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop reading the petrol pump. - Stop the moment you notice. Less petrol in your tank means a thinner mix. It does not change what to do next, which is still not to crank it. ## Petrol already in a diesel in Outwood Gate? Start here The order of things is brief, then. Leave it unstarted, with the ignition switched off as well. Still on the forecourt, at Asda or anywhere else? Ask the staff to help you push it away from the pump. Then ring 0333 366 0103 and tell us what got in, about how much, and whether it has run. Say so if it was AdBlue instead of petrol: it is a different fault, with its own page for Outwood Gate, since AdBlue brings corrosion and deposits instead of lost protection. ## Why one petrol in a diesel task in Outwood Gate costs more than another The four scenarios above are four different jobs, so no single quote for this would be honest. The scenario itself does most of the work of moving your cost. The ratio counts next, meaning how much of the tank is petrol, and then the location of the car and whether reaching it is safe for a technician. Three questions come first, before quoting, rather than after — what was put in, how much, has it run — and that is the reason. A range becomes a straight figure once the replies are in. ## About Outwood Gate Outwood Gate is a suburban area situated on the outskirts of Salford, near the lakeside in Greater Manchester.
