Not started? Then less anxious than you likely are. Till your ignition primes your pump, your starter cranks, or your car is driven, petrol in a diesel tank simply waits there and does no harm. Which means the truthful reply to that first Kirkhill question — "have I wrecked it?" — normally no. Keep it that way: leave your engine off and phone Petrol in Diesel. Read on for three things: the effect petrol has inside a diesel engine, the signs of how far it has got, and ways to make sure you never do it again. ## Inside the engine: what petrol in a diesel does Passing through an engine, diesel is doing two jobs at the same time. Lubricating comes before burning; it does both. Made to very fine tolerances, the injectors and your pump depend on the diesel flowing through them to keep their surfaces from wearing against one another. Of these two tasks, petrol handles the first badly and the second not at all. Being less viscous than diesel, petrol strips away the lubrication a fuel system needs, leaving a pump on the mixture to wear itself. It's also made to resist igniting under compression — the opposite of what a diesel needs — which is why you get the clattering. Together, those leave the shape of the issue clear. It's movement that causes the harm, not contact. Petrol in a tank is a fuel problem. The beginning of a mechanical problem is a pump that has been working on that petrol — and whatever a worn pump sheds travels on with your fuel to the injectors downstream. ## Petrol in a diesel in Kirkhill: how serious is it? Four situations Fuelled but not once started — as good as it gets. That petrol is in your tank and just your tank, and the job is a drain and a flush where the vehicle stands. This is the one scenario that can only truly happen at a forecourt, since anywhere else the car has been driven to get there. A moment's running, or merely the ignition on. Once primed, the system has pulled petrol out of the tank up to the fuel filter and your lines. That's normally still a straightforward task — a drain, a flush, and the filter dealt with. Your pump has spent a couple of miles on weakened fuel — that is what driving the vehicle does. Miles is only half of that; how hard it was driven matters equally. Either way the work runs to the tank, your lines, your filter and clean fuel through the entire system. The school run to the local primary school is one thing. Any distance on the M77, under 3 miles from Kirkhill, means the engine working hard throughout, and a run to Glasgow, under 10 miles away, is a very different task too. Driven on until it complained — clattering, smoke, a ragged idle, a dead throttle. The engine is telling you the fuel is no longer acting like diesel. Pull up on the spot — on the verge on The Dell, at the kerb, down a side road — and don't move it again. A car pulled over early very rarely has long-term damage, since the drain and the flush, which still come first, sort it out. ## Petrol in a diesel myths Kirkhill people hear False: topping up to full with diesel makes it fine. It doesn't. Nothing is removed by topping up — you're left with a fuller tank, still the same mix. Percentage isn't how a diesel fuel system tolerates petrol, however much that guidance presumes. Myth: a newer diesel copes with a bit of petrol. If anything, the reverse. At higher pressure, through finer parts: that's how a modern diesel handles its fuel, and so the protection matters more, not less. The myth that catches people out: if it starts and drives, it must be unharmed. Any petrol engine fed diesel usually will not run, and so the driver stops and the damage stops with them. While the pump wears, a diesel fed petrol usually starts, ticks over and drives away as if nothing has happened. Running isn't the same as fine. Not so: a two-stroke additive lets you to drive home. It was an old fix, supposed for another problem. The petrol is still inside your tank after that, and what it has diluted isn't put back. Myth: "Drain that tank yourself and you're sorted." Once the motor has run, some of that petrol is no longer inside that tank: it is in your filter and the fuel lines, and it goes straight back through the pump on the next start. Also, a can of petrol filled at the kerbside is genuinely hazardous. ## Petrol in a diesel: how does it take place? It is seldom carelessness, and no one does it on purpose. The petrol nozzle is the narrower of the two and slips into a diesel filler with almost no resistance; a diesel nozzle generally will not go into a petrol motor at all. The forecourt makes it easy, and the slip runs one way. Habit and the vehicle getting out of step is how it happens. Courtesy car, hire car, or a motor that is brand new. One petrol and one diesel on the drive of the same household. The pumps in a different order on a familiar forecourt. A train to catch, and a hurried fill on the way to Whitecraigs. A new-to-you diesel Renault Megane, its first fuelling, and a motorist accustomed to petrol: precisely when it occurs. Throw in rain, a phone call or a back seat full of kids, and the hand repeats what it has always done. ## Next time you fill up in Kirkhill: avoiding petrol in a diesel - The label is what matters, so check the petrol pump instead of the colour: in the UK unleaded handles are normally green and diesel black, yet not on each forecourt. - Check your filler flap. Many vehicles state the fuel inside the flap or on the cap. Look at it on your first fill in any vehicle you don't know. - Mark your key. In a household with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember. - It sounds daft and it works: on your first fill in a new or hired car, say "diesel" aloud before you lift the nozzle off the petrol pump. - While you are thinking about something else, this is an easy mistake to make — so tuck your phone away. - A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to block a petrol nozzle, and add-on devices are available for vehicles without one. They are a safety net, not a reason to stop checking the pump. - As soon as you realise, stop: less petrol in the tank means a thinner blend. What to do next does not change, though — still do not fire it up. ## Already put petrol in a diesel in Kirkhill? Then the order of things is short. Starting it is out, and so is turning on your ignition. Ask the attendants to help you push it clear of the pump if you're still on the forecourt, whether that's Whitecraigs BP or anywhere else. Call 0333 366 0103 next, with three facts — your fuel, the approximate quantity, and whether it has run. AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a separate fault — Kirkhill has a page just for it. ## Kirkhill petrol in a diesel jobs: why one costs more than another A fair single price doesn't exist here: four scenarios, four separate tasks. Which of them you're in is mostly what moves your cost. Two things follow that: the petrol that was put in as a proportion of what the tank holds, then the place the vehicle is in and whether a van can get to it safely. Three questions come first, before quoting, instead of after — what got in, how much, has it run — and this is the reason. A range turns into a straight figure when the answers are in. ## About Kirkhill Kirkhill is a suburban area situated on the riverside in East Renfrewshire, with a mix of detached housing and other residential properties.
