How Worried Should You Be? Petrol in a Diesel Car in Dukes Meadow
Unstarted? Then less worried than you probably are. Till the ignition primes the pump, the starter cranks, or your vehicle is driven, petrol in a diesel tank just rests there and does nothing. Which means the honest reply to the first Dukes Meadow question — "have I wrecked it?" — normally no. To keep it that way, ring Petrol in Diesel then leave your motor alone. Keep reading for three things: the effect petrol has inside a diesel motor, the clues of how far it has got, and ways to make sure you never do it again.
The motor and petrol in a diesel: what goes on
Two tasks fall to diesel on its route through a motor. It lubricates first, and after that does it burn. Designed to extremely fine clearances, your injectors and the pump depend on the diesel flowing through them to stop their surfaces wearing against one another.
Poorly at the first, not at all at the second: that is petrol. The clattering comes from petrol being designed not to ignite when compressed, which is precisely the opposite of what a diesel needs. On top of that it is thinner than diesel, it strips out the lubrication the system hinges on, and any pump working on that mixture is wearing itself.
Put those together and the shape of the issue is plain. It's circulation that does the damage, not contact. All a tank with petrol in it amounts to is a fuel problem. The start of a mechanical one is a pump that has been running on that petrol — and whatever a worn pump sheds moves on with the fuel to the injectors beyond it.
How serious is petrol in a diesel? Four scenarios our engineers see in Dukes Meadow
Fuelled, and never started: nothing beats it. That petrol is inside your tank and only the tank, and the job is a drain and a flush where your car sits. This is the one situation that can only truly happen at a forecourt, as anywhere else your car has been driven to get there.
Ignition on, or started for a moment. With your system primed, the fuel lines and filter now contain petrol that has come from your tank. That's usually still a straightforward job — a drain, a flush, and the fuel filter dealt with.
Those few miles on the road meant your pump running on fuel thinned by petrol throughout. Mileage is only half of that; how hard it was driven matters equally. Either way the work runs to your tank, your lines, the fuel filter and fresh fuel through the entire system. Short trips, like the school run to the local primary school, are one thing. A run as far as Newport, under 25 miles away, is a very different job. So is any distance on the M4, under 25 miles from Dukes Meadow, where the motor has been labouring hard throughout.
It protested, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone uneven. What you are hearing is your motor signalling fuel that no longer runs like diesel. Pull up where you are — on the verge on Glanhowy Street, at the kerb, down a side road — and do not move it. The fuel drain and flush still come first, and they take care of it: if a car is pulled over early, lasting damage is very uncommon.
Dukes Meadow drivers and the petrol in a diesel myths they hear
Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Nothing is removed when you top up — your tank simply carries more of the same mixture. A diesel fuel system doesn't accept petrol by percentage in the way that guidance presumes.
Myth: "A current diesel can cope with a bit of petrol." If anything, the opposite. More precise components and higher pressure are the way a newer diesel runs its fuel, and that makes the protection matter more, not less.
"It starts, it drives, so no harm done" — the myth that catches more drivers than any other. The driver of a petrol motor fed diesel usually has no choice but to stop, because it will not run, and the damage stops there. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually will; meanwhile your pump grinds. Being able to run isn't the same as being fine.
Myth: a two-stroke additive makes it safe to drive home. It was an old fix, supposed for another issue. What petrol has weakened stays weakened, and that petrol stays inside your tank anyway.
Once your engine has been run, part of the petrol is in the fuel filter and the lines, not that tank — and your next start sends it straight back through your pump. So the myth "drain your tank yourself and you are sorted" does not hold. It is also really risky to drain petrol into a can at the roadside.
How does petrol in a diesel occur?
Carelessness is rarely the cause, and no one means to do it. A diesel nozzle mostly won't fit a petrol vehicle, yet the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake simple, and just in one direction.
When routine and the car stop matching, it happens. Hire cars, courtesy cars, and cars that are new to you. One petrol and one diesel on the drive of the same household. The pumps in a different order on a familiar forecourt. Filling up in a rush en route to Ebbw Vale Town, with a train to catch. The first fill-up in a diesel Renault Megane after years of driving petrol is precisely the moment it happens. Throw in rain, a phone call or a back seat full of children, and the hand does what it has always done.
Dukes Meadow people: how to prevent petrol in a diesel next time
- The label is what counts, and so read the petrol pump instead of the colour: in the UK unleaded handles are normally green and diesel black, yet not on each forecourt.
- Many motors state the fuel inside the filler flap or on the cap, and so check there on your first fill in a motor you do not know.
- A coloured fob or a sticker on your diesel's key does more than any amount of intending to remember, for a home with one of each.
- "Diesel", aloud, before you pick up the nozzle — each time a new or hired car needs its first tank. It seems daft. It does the trick.
- Mistakes like this are straightforward to make whilst your mind is on something else, so the phone goes away.
- Add-on devices exist for cars without one, and some diesels come with a filler that won't accept a petrol nozzle. Useful — but a backstop at best, never a reason to stop checking the label.
- As soon as you notice, stop: less petrol in the tank means a thinner blend. What to do next doesn't change, though — still do not crank it.
Put petrol in a diesel in Dukes Meadow already?
Short and simple, then, is the order of things. Leave it unstarted, with your ignition off as well. If you're still on the forecourt — Texaco or anywhere else — ask the attendants to help you push the car clear of the pump. What got in, roughly how much, and whether it has run: tell us that when you ring 0333 366 0103.
Say so if it was AdBlue rather than petrol: it's a different issue, with its own page for Dukes Meadow, since AdBlue brings corrosion and deposits instead of lost lubrication.
One petrol in a diesel job around Dukes Meadow costs more than another. Why?
The four situations above are four different tasks, so no single quote for this would be fair. Chiefly, your cost moves with which situation you are in. Where the vehicle is counts too, and whether our van can safely reach it, after the proportion of petrol to what that tank holds.
That is why our engineers ask three questions before costing instead of after: what was put in, how much, and whether it's run. Those replies turn a range into a straight figure.
