How Worried Should You Be? Petrol in a Diesel Car in Ouzlewell Green
Less than you probably are, if it hasn't been started. "Have I wrecked it?" is the first thing anyone around Ouzlewell Green asks, and the honest answer is usually no, because petrol resting in a diesel tank harms nothing until it is drawn through the fuel system — by ignition priming, by the starter, or by being driven. Leave your engine off and phone Petrol in Diesel — that keeps it like that. Keep reading for three things: the effect petrol has inside a diesel engine, the clues of how far it has got, and ways to make sure you never do it again.
The engine and petrol in a diesel: what goes on
Two tasks fall to diesel on its route round a motor. It combusts, and before it burns it protects. Extremely fine tolerances are built into the injectors and the high-pressure pump, and just the diesel running through keeps those surfaces from grinding together.
Badly at the first, not at all at the second: that's petrol. The clattering comes from petrol being designed not to ignite when compressed, which is precisely the reverse of what a diesel needs. On top of that it is runnier than diesel, it strips out the protection your system rests on, and any pump working on such a mix is wearing itself.
Put these together and the shape of the issue is clear. The harm is done by circulation, not by contact. Any tank with petrol in it is a fuel issue. Whatever a worn pump sheds travels on, borne by the fuel, into the injectors downstream, which is why a pump that has worked on that petrol is where a mechanical issue begins.
Petrol in a diesel in Ouzlewell Green: how bad is it? Four situations
The best case there can be: filled up, never started. Being on a forecourt is what makes this possible: elsewhere, the vehicle has been driven there to begin with. With that petrol kept in that tank alone, it is emptied and rinsed on the spot, and nothing more is needed.
Ignition on, or started for a moment. With the system primed, your lines and filter now contain petrol that has come from your tank. Drain, flush, deal with the fuel filter: still normally easy.
The pump has spent a few miles on diluted fuel — that's what driving the car meant. Tank, lines, filter, then clean fuel put through the whole system: that is this work, and the way the vehicle was driven matters as much as the mileage. A school run to Carlton Primary School is one matter. A run as far as Wakefield, under 5 miles away, is a very different job. So is any mileage on the M62, under a mile from Ouzlewell Green, where your engine has been working hard the whole time.
It complained, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone ragged. The motor is telling you your fuel is no longer acting like diesel. Leave it where it stops: a lay-by, a side street, the verge on Greenmoor Court. Permanent damage is very rare when a vehicle is pulled over soon, and the fuel drain and flush-through that still come first sort it out.
Myths Ouzlewell Green motorists hear about petrol in a diesel
Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Topping up takes out nothing; it gives you a bigger tank of the same mixture. Percentage is not how a diesel fuel system tolerates petrol, however much that advice assumes.
Myth: "A modern diesel can cope with a bit of petrol." If anything, the reverse. A modern diesel runs its fuel through finer components at higher pressure, which makes the protection count more, not less.
This is the one that fools people. Myth: "If it starts and drives, there's no damage done." Diesel in a petrol motor normally means a motor that will not run: the driver stops, and so does the damage. A diesel fed petrol normally starts, ticks over and drives away as though nothing has happened, while the pump wears. A running engine does not mean fine.
Myth: "Add some two-stroke oil and drive the vehicle home." It is an outdated workaround for a different problem. It does not put back what petrol has diluted, and the petrol is still inside that tank later.
"Drain it yourself and you are sorted" — a myth, since after it's been running some petrol sits in the filter and lines, ready to go straight back through your pump at the next start. Draining petrol into a can at the roadside is also really risky.
Why petrol in a diesel takes place at all
Carelessness is rarely the cause, and no one means to do it. One way only, since of the nozzles: the narrower petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one mostly will not fit a petrol car. That is how the forecourt makes it simple.
When habit and the car stop matching, it takes place. A new vehicle, a hire car or a courtesy car. One petrol and one diesel on the driveway of the same household. A forecourt you know, only with its pumps arranged differently. A hurried fill en route to Outwood with a train to catch. The first fill-up in a diesel Volkswagen Golf after years of driving petrol is precisely the moment it occurs. Add a back seat full of kids, a phone call or rain, and the hand takes over.
Avoiding petrol in a diesel next time you fill up around Ouzlewell Green
- Green for unleaded and black for diesel is normal in the UK — yet not on each forecourt. Trust the label on the pump, not the colour.
- Many vehicles state the fuel inside the filler flap or on the cap, so check it on your first fill in a vehicle you do not know.
- One of each in the household? Mark your key to your diesel — a bright fob, a sticker — because intending to remember is not enough.
- "Diesel", out loud, before you lift the nozzle — every time a new or hired car gets its first tank. It seems silly. It works.
- While you're thinking about something else, this is an easy mistake to make — so put the phone away.
- Some diesels come with a filler built to reject a petrol nozzle, and devices you can add are available for motors without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop checking the pump.
- The moment you notice, stop: less petrol inside that tank makes a thinner mixture. What to do next doesn't change, though — still don't start the vehicle.
Ouzlewell Green: already put petrol in a diesel?
Then, there's only a short order of things. Don't switch the ignition on, and don't crank it. If you're still at the forecourt — Robin Hood Service Station or anywhere else — ask the attendants to help you push it away from the petrol pump. Then call 0333 366 0103 and tell us what went in, roughly how much, and whether it's run.
AdBlue, not petrol? Then say so. Corrosion and deposits, not lost lubrication, make it a different problem — Ouzlewell Green has a page all for it.
Why one petrol in a diesel task in Ouzlewell Green costs more than another
Four separate tasks sit behind the four scenarios above — which is why there's no fair single quote. What shifts your cost is chiefly which of them you are in. Where the vehicle is counts too, and whether our van can safely get to it, after the proportion of petrol to what your tank holds.
That is why our engineers ask three queries before pricing rather than after: what went in, how much, and whether it's run. Their answers are what change a range into one firm number.
