Petrol in a Diesel Car in Burscough Bridge Not started? Then less anxious than you probably feel. Till the ignition primes the pump, your starter turns, or the car is driven, petrol in a diesel tank just rests there and does nothing. Which means the honest reply to the first Burscough Bridge question — "have I wrecked it?" — normally no. To leave the car like that, call Petrol in Diesel then leave your engine switched off. Further down, this page sets out what petrol really does inside a diesel, how far it might have gone, and how to stop it happening to you again. ## Petrol in a diesel: what does it do to the engine? Two jobs fall to diesel on its route round a motor. It lubricates first, and only then does it burn. Extremely fine clearances are built into your injectors and your high-pressure pump, and just your diesel running through stops their surfaces grinding together. Poorly at the first, not at all at the second: that is petrol. A pump working on a petrol mix is wearing itself out, because petrol is runnier than diesel and strips out the lubrication your fuel system depends 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 rattling comes. Taken together, they make clear what shape the problem takes. Contact does not do the harm — movement does. Where the petrol is only in your tank, it is an issue of fuel, nothing more. A pump that has been labouring on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds moves on with the fuel to your injectors further on. ## How serious is petrol in a diesel? Four situations we see in Burscough Bridge Fuelled but never started — as good as it gets. That petrol is inside that tank and just your tank, and the job is a drain and a flush where your car stands. This is the one scenario that can only really occur at a forecourt, because anywhere else the vehicle has been driven to get there. A brief spell of running, or merely your ignition on. With your system primed, the lines and filter already contain petrol that came from that tank. Drain, flush, deal with your filter: still usually simple. Driven a few miles. Now the pump has spent those miles working on weakened fuel. Tank, lines, filter, then fresh fuel run through the whole circuit: that's the work, and the way the vehicle was driven counts as much as the distance. Short trips, like the school run to Burscough Bridge St John's Church of England Primary School, are one matter. Getting as far as Preston, under 15 miles away, makes a very different job — as does any mileage on the M58, under 5 miles from Burscough Bridge, with your engine working hard all the way. Driven on until it complained — clattering, smoke, an uneven idle, a dead throttle. The fuel isn't behaving like diesel any more, and the motor is saying so. Pull up where you are — on the verge on Liverpool Road North, at the kerb, down a side road — and don't move it again. The drain and flush-through still come first, and they sort it out: when a vehicle is pulled over quickly, lasting damage is very unusual. ## Burscough Bridge motorists and the petrol in a diesel myths they hear "Top it up the rest of the way with diesel and it will be fine" — a myth. It won't. Nothing is removed by topping up — you are left with a bigger tank, still the same mix. Percentage isn't how a diesel fuel system copes with petrol, however much that guidance supposes. If anything, the opposite holds. Myth: "A modern diesel can cope with a bit of petrol." Smaller parts and higher pressure are how a current diesel runs its fuel, and that makes the protection count more, not less. One myth that catches people off guard: if it starts and drives, it must be unharmed. The driver of a petrol engine fed diesel usually has no choice but to stop, because it will not run, and the damage stops with them. Feed petrol to a diesel and it normally starts, ticks over and pulls away like nothing happened — all the while its pump wears. Being able to run isn't the same as being fine. Not so: a two-stroke additive lets you to drive home. It was an old workaround, supposed for another issue. It doesn't put back what petrol has thinned, and that petrol is still inside your tank later. The next start draws petrol back round your pump from the fuel lines and the fuel filter, where some of that sits once the engine has run. That is why draining your tank yourself doesn't leave you sorted — a myth. On top of that, petrol emptied into a can by the road is truly dangerous. ## How petrol ends up: petrol in a diesel On purpose? Never. Through carelessness? Seldom, if ever. A diesel nozzle mostly will not go into a petrol car, but the slimmer petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one error straightforward, and just in one direction. Routine and the car getting out of step is how it occurs. Any car 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 the nearest station and fuelling up en route. Exactly the moment it takes place: after years of driving petrol, someone fills a diesel Volkswagen Golf for the first time. Add rain, a phone call or a back seat full of children, and the hand does what it has always done. ## Preventing petrol in a diesel next time you fill up in Burscough Bridge - The label is what counts, so read the pump rather than the colour: in the UK unleaded handles are normally green and diesel black, but not on each forecourt. - The first fill in a new car is the time to check the filler flap — on it, or on the cap, many cars state the fuel to use. - A coloured fob or a sticker on your diesel's key achieves more than any amount of intending to remember, in a household with one of each. - It sounds daft and it works: on the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump. - Thinking about something else is when this becomes an easy mistake to make, so put the phone away and keep your mind on the pump. - Some diesels have a filler designed to block a petrol nozzle, and devices you can add are available for cars without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop checking the petrol pump. - Spotting it mid-fill? Stop there and then. A weaker blend results from less petrol in the tank, yet your next stage remains the same: don't start it. ## Put petrol in a diesel around Burscough Bridge already? The order of things is brief, then. Never start the car, and do not switch the ignition on. Yet on the forecourt, at Esso or anywhere else? Ask the staff to help you roll the vehicle clear of the petrol pump. Next, 0333 366 0103. We'll ask what got in, roughly how much, and if it has been run. AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a separate problem — Burscough Bridge has a page just for it. ## One petrol in a diesel job around Burscough Bridge costs more than another. Why? The four scenarios above are four different tasks, so no single price for this would be fair. Which of them you're in is chiefly what moves the cost. Next it's the share — how much petrol got in against how much the tank holds — and after that where the vehicle is and whether a van can reach it safely. What got in, how much, and if it has run — three questions we ask before quoting, not after, for exactly that reason. A range becomes a straight figure once those replies are in. ## About Burscough Bridge, briefly Burscough Bridge is a village situated on the banks of the Leeds and Liverpool Canal in Lancashire, with a mix of semi-detached housing and local amenities.
