Should You Worry? Petrol in a Diesel Car in Garden Village
Unstarted? Then less worried than you likely feel. Till your ignition primes the pump, the starter turns, or the vehicle is driven, petrol in a diesel tank just sits there and does no harm. Which makes the truthful reply to that first Garden Village query — "have I wrecked it?" — normally no. Leave the motor off and call Petrol in Diesel — that keeps it that way. The rest of this page covers what petrol actually 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.
What petrol in a diesel does to the engine
On its way through an engine, diesel does two jobs. Lubricating comes before burning; it does both. What stops the surfaces inside the high-pressure fuel pump and the fuel injectors from wearing against each other is your diesel flowing through them — they are built to extremely fine gaps.
Petrol does the first job poorly and the second not at all. Being less viscous than diesel, petrol strips away the protection a fuel system needs, leaving a pump on that mixture to wear itself. It is equally made to resist igniting under compression — the reverse of what a diesel needs — which is why you get the clattering.
Put those together and the shape of the issue is clear. The damage is done by circulation, not by contact. All a tank with petrol in it amounts to is a fuel fault. After the pump has been working on that petrol, a mechanical issue has started: anything shed by a pump that is wearing down travels onward to the injectors with your fuel.
Petrol in a diesel around Garden Village: how serious is it? Four cases
Fuelled, and not started: no case is better. That petrol is in that tank and just that tank, and the job is a drain and a flush where the car stands. This is the one situation that can only truly take place at a forecourt, as anywhere else the vehicle has been driven to get there.
Started for a moment, or just your ignition on. Your system has been primed, so petrol has left the tank and reached your filter and the fuel lines. Normally nothing more than clearing, flushing and sorting your filter, and so still straightforward.
Those few miles driven were your pump labouring on fuel diluted by petrol throughout. Tank, lines, filter, then clean fuel put through the whole circuit: that is this work, and the way the vehicle was driven matters as much as the distance. On the school run to Weston Rhyn Primary School, the miles is small. Getting as far as Wrexham, under 10 miles away, makes a very different task — as does any distance on the M53, under 25 miles from Garden Village, with your engine labouring hard all the way.
Driven until it protested. Knocking, an uneven idle, smoke, a throttle that has gone soft. What you are hearing is your motor reporting fuel that no longer acts like diesel. Whether it is the verge on Ifton Fields, a lay-by or a side street, stop where you are then leave it. What goes first is still the drain and flush, and that takes care of it, with long-term damage very unusual when a car is pulled over quickly.
What Garden Village people get told about petrol in a diesel — and the myths in it
It will not be fine. The myth: "Fill it the rest of the way with diesel and it'll be." Nothing comes out when you top up — that tank just carries more of the same mixture. The assumption behind the guidance — that diesel fuel systems tolerate petrol by percentage — is wrong.
Not so: a modern diesel copes with a bit of petrol. If anything, the opposite. Finer components and higher pressure are how a modern diesel runs its fuel, and that makes the protection count more, not less.
Myth: "If it starts and drives, there's no harm done." This is the one that catches people. Feed diesel to a petrol engine and it generally will not run, and so the motorist stops — and the harm 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 the pump wears. Being able to run is not proof of being fine.
An outdated fix for a different issue is behind this one. Myth: "Add some two-stroke oil and drive the car home." What petrol has weakened remains thinned, and that petrol stays inside the tank regardless.
"Drain it yourself and you're sorted" — a myth, since after it's been running some petrol sits in your filter and lines, waiting to go right back through your pump at the next start. Besides, petrol emptied into a can by the road is genuinely dangerous.
Petrol in a diesel: how does it take place?
No one does it on purpose, and it's rarely carelessness. A diesel nozzle generally will not fit a petrol motor, yet the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one error straightforward, and just in that direction.
It occurs when habit and the car stop matching. Courtesy car, hire car, or a motor that is new. Two vehicles on one drive, one petrol, one diesel. The pumps in a different order on a well-known forecourt. Filling up in a hurry on the way to Gobowen, with a train to catch. Precisely the moment it occurs: after years of driving petrol, someone fills a diesel Volkswagen Golf for the first time. Throw in rain, a phone call or a back seat full of kids, and your hand repeats what it has always done.
Garden Village drivers: how to prevent petrol in a diesel next time
- Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most generally do. Read the petrol pump's label; the colour is only a clue.
- Plenty of cars state the fuel inside the filler flap or on the cap, so check there on your first fill in any car you don't know.
- A coloured fob or a sticker on your diesel's key does more than any amount of meaning to remember, for a household with one of each.
- "Diesel", aloud, before you lift the nozzle — each time a new or hired car gets its first tank. It sounds daft. It does the trick.
- Mistakes like this are straightforward to make while your mind is on something else, so your phone goes away.
- Some diesels come with a filler designed to refuse a petrol nozzle, and devices you can add exist for vehicles without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the pump.
- Less petrol makes a weaker mix, so stop the moment you notice — while remembering that the next stage is unchanged. It's still not to crank it.
Petrol already in a diesel around Garden Village? Start here
The order of things is brief, then. Starting it is out, and so is switching on the ignition. Still at the forecourt, at Texaco or anywhere else? Ask the attendants to help you push it away from the petrol pump. Then phone 0333 366 0103 and tell us what was put in, about how much, and whether it has run.
Corrosion and deposits form the issue with AdBlue, whereas petrol brings lost protection. So if it was AdBlue, say so — and see its own Garden Village page.
What makes one Garden Village petrol in a diesel job cost more than the next
There is no fair single quote for this, since the four situations above are four different jobs. Which of them you are in is chiefly what moves your cost. Where the vehicle is matters too, and whether a van can safely get to it, after the ratio of petrol to what the tank holds.
That's why we ask three questions before costing instead of after: what went in, how much, and if it has run. Those replies change a range into a straight figure.
