How Worried Should You Be? Petrol in a Diesel Car in Rugeley
Likely less than you are now — as long as no one has started the car. Until your ignition primes the pump, your starter cranks, or your vehicle is driven, petrol in a diesel tank simply waits there and does no harm. Which makes the honest reply to that first Rugeley question — "have I wrecked it?" — usually no. To keep it like that, ring Petrol in Diesel and leave your motor switched off. Further down, you will find what petrol actually does inside a diesel, how far it might have got, and how to stop it happening to you a second time.
Your engine and petrol in a diesel: what happens
Passing through a motor, diesel does two things at the same time. Before it combusts, it protects — then it ignites. The high-pressure fuel pump and the fuel injectors are made to very fine clearances, and the diesel passing through them is what stops those surfaces from wearing against one another.
Badly at the first, not at all at the second: that is petrol. A pump working on a petrol blend is wearing itself out, since petrol is runnier than diesel and strips out the protection the fuel system relies on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel needs from its fuel — and that's where any clattering starts.
Put those together and the shape of the trouble is clear. It is movement that does the damage, not contact. Where the petrol is only in that tank, it's an issue of fuel, nothing more. 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.
Rugeley, petrol in a diesel: four situations, from mild to significant
Fuelled but not once started — as good as it gets. The petrol is inside the tank and just your tank, and the task is a drain and a flush where your car stands. This is the one scenario that can only truly occur at a forecourt, since anywhere else the vehicle has been driven to get there.
Ignition on, or started for a second. With the fuel system primed, the lines and filter now hold petrol that came from that tank. Still usually straightforward: drain, flush, and the fuel filter seen to.
Driven a few miles. Now your pump has spent those miles labouring on weakened fuel. The work is the tank, the lines, your filter and fresh fuel through the whole circuit, and how hard the car was driven matters as much as how far. A school run to Chancel Primary School is one thing. Any miles on the M6 Toll, under 10 miles from Rugeley, means your engine has worked hard throughout, and a run to Lichfield, under 10 miles away, is a very different job too.
Driven until it protested. Clattering, an uneven idle, smoke, a throttle that has gone soft. That's the engine telling you its fuel no longer is acting like diesel. Pull up where you are — on the verge on Anson Street, at the kerb, down a side road — and don't move it. Lasting damage is very uncommon if a vehicle is pulled over soon, and the fuel drain and flush that still come first take care of it.
Petrol in a diesel myths Rugeley people hear
False: topping up to full with diesel makes it fine. It does not. Topping up removes nothing; it gives you a fuller tank of the same mix. That guidance supposes a diesel fuel system handles petrol by percentage. It doesn't.
If anything, the reverse holds. Myth: "A current diesel can cope with a bit of petrol." Smaller components and higher pressure are the way a newer diesel runs its fuel, and that makes the lubrication count more, not less.
Myth: "If it starts and drives, there is no damage done." This is the one that catches motorists. Feed diesel to a petrol motor and it usually will not run, and so the motorist stops — and the harm stops with them. Feed petrol to a diesel and it generally fires up, ticks over and pulls away like nothing happened — all while its pump is wearing. A running engine does not mean fine.
Not so: a two-stroke additive lets you to drive home. It was an old workaround, meant for another problem. None of what petrol weakened is put back by it — and afterwards, the tank still contains the petrol.
If the engine has been run, part of that petrol is in the fuel filter and the lines, not the tank — and the next start pulls it right back through your pump. So the myth "drain the tank yourself and you are sorted" does not hold. On top of that, petrol cleared into a can by the road is truly dangerous.
Petrol in a diesel: how does it take place?
It's seldom carelessness, and nobody does it on purpose. One way only, since of the nozzles: the narrower petrol one slides inside a diesel filler with almost no resistance, while the diesel one mostly will not fit a petrol car. That's how the forecourt makes it simple.
Habit and your car falling out of step is how it happens. Courtesy car, hire car, or a vehicle that is brand new. One petrol and one diesel on the drive of the same household. Your normal forecourt, its pumps now in a different order. A train to catch, and a hurried fill en route to Rugeley Town. Precisely the moment it happens: after years of driving petrol, someone fills a diesel Renault Megane for the first time. The hand does what it has always done once you add rain, a phone call or a back seat full of kids.
Preventing petrol in a diesel next time you fill up around Rugeley
- Check the petrol pump, not the colour. In the UK unleaded handles are generally green and diesel black, but not on every forecourt. The label is what matters.
- The first fill in a strange car is the time to check the filler flap — on it, or on the cap, plenty of vehicles state which fuel to use.
- Good intentions count for less than a sticker or a fob in a vivid colour on the diesel's key if a home has one of each. So label it.
- Before the nozzle leaves the petrol pump the first time you fuel a hired or new vehicle, say "diesel" aloud. Silly, perhaps, yet it works.
- Tuck the phone away. This is an easy mistake to make whilst you are thinking about something else.
- Add-on devices exist for motors without one, and some diesels are built with a filler that won't take a petrol nozzle. Useful — but a backstop at best, never a reason to stop checking the label.
- Noticing it halfway? Stop there and then. A thinner mixture follows from less petrol inside that tank, but your next step remains the same: do not crank it.
Put petrol in a diesel around Rugeley already?
Short and simple, then, is the order of things. Starting it is out, and so is switching on the ignition. Ask the attendants to help you roll it away from the petrol pump if you're still on the forecourt, whether that is Shell or anywhere else. What was put in, about how much, and whether it has run: tell us those when you phone 0333 366 0103.
AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a separate fault — Rugeley has a page just for it.
One petrol in a diesel task in Rugeley costs more than another. Why?
There's no honest single quote for this, because the four situations above are four separate tasks. Chiefly, your cost shifts with which one you are in. Next it is the share — how much petrol went in against how much your tank takes — and then where the car is and whether a technician can reach it safely.
What was put in, how much, and whether it has run — three questions our engineers ask before costing, not after, for exactly that reason. Given the answers, you get a straight figure instead of a range.
