Everton: Petrol in a Diesel Car? How Worried to Be
Probably less than you already are — as long as nobody has started the vehicle. Petrol sitting in a diesel tank does nothing to your motor until something draws it through your fuel system — your ignition priming the pump, the starter, or driving itself. So the honest answer to the first question anyone around Everton asks, "have I ruined it?", is usually no. To leave it like that, ring Petrol in Diesel then leave the engine alone. Further down, this page sets out what petrol really does inside a diesel, how far it might have got, and how to stop it happening to you again.
Inside the motor: what petrol in a diesel really does
Diesel has two jobs on its way through an engine. It combusts, and before it ignites it lubricates. Made to extremely fine gaps, the fuel injectors and the pump depend on the diesel flowing through them to keep their surfaces from wearing against one another.
Poorly at the first, not at all at the second: that is petrol. The knocking comes from petrol being made 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 fuel system rests on, and any pump running on such a mixture is wearing itself.
Put these together and the shape of the issue is plain. It is movement that does the harm, not contact. All a tank with petrol in it amounts to is a fuel problem. A pump that has been labouring on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds moves on with your fuel to your injectors further on.
Petrol in a diesel around Everton: how serious is it? Four situations
Fuelled up, not once started. The best case there can be. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With the petrol held inside the tank alone, it is emptied and flushed right where it stands, and nothing more is needed.
Started for a moment, or only the ignition on. Petrol has left the tank and reached your filter and your lines, since the fuel system has been bled. Usually nothing more than clearing, cleaning and sorting the filter, so still simple.
A few miles driven, and the pump has spent each of them labouring on weakened fuel. Tank, lines, filter, then fresh fuel put through the whole circuit: that's the work, and the way your car was driven matters as much as the miles. Short trips, like the school run to Milford-on-Sea Church of England Primary School, are one matter. Any mileage on the M27, under 15 miles from Everton, means the motor has worked hard throughout, and a run to Southampton, under 15 miles away, is a very different task too.
Rattling, a lumpy idle, smoke, a throttle gone soft: driven until it complained. What you are hearing is your engine signalling fuel that no longer acts like diesel. Stop where you are — on the verge on Frys Lane, at the kerb, down a side road — and don't move it again. What comes first is still the fuel drain and flush, and that deals with it, with permanent damage very unusual if a car is stopped soon.
Petrol in a diesel stories Everton drivers hear
It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Nothing is removed by topping up — you're left with a bigger tank, still the same mixture. That advice supposes a diesel fuel system tolerates petrol by percentage. It doesn't.
"Modern diesels can handle a little petrol" — a myth, and closer to the reverse. Smaller components and higher pressure are the way a current diesel runs its fuel, and that makes the protection count more, not less.
One myth that catches motorists out: if it starts and drives, it must be unharmed. Diesel in a petrol motor generally leaves a motor that will not run: the motorist stops, and so does the damage. Feed petrol to a diesel and it normally starts, idles and drives away as if nothing happened — all the while its pump wears. Running does not mean fine.
Myth: "Add some two-stroke oil and drive the vehicle home." It's an old workaround for a different problem. None of what petrol thinned is put back by it — and afterwards, the tank still holds that petrol.
The next start sends petrol back round the pump from the lines and your filter, where some of it sits after the motor has been run. That is why a DIY tank drain doesn't leave you sorted — a myth. Also, a can of petrol filled at the roadside is truly risky.
How petrol ends up: petrol in a diesel
Nobody does it on purpose, and it's rarely carelessness. A diesel nozzle mostly won't fit a petrol vehicle, yet the slimmer petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake simple, and only in that direction.
When routine and your car stop matching, it occurs. Any motor that's new to you — hired, on loan as a courtesy car, or brand new. A household with one petrol and one diesel on the drive. A well-known forecourt with the pumps in a different order. Filling up in a hurry on the way to Lymington 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 takes place. Throw in rain, a phone call or a back seat full of children, and the hand repeats what it has always done.
How to avoid petrol in a diesel at your next fill-up around Everton
- Not every forecourt in the UK follows green for unleaded and black for diesel, though most usually do. Read the pump's label; the colour is only a hint.
- Check your filler flap. Plenty of vehicles state the fuel type inside the flap or on the cap. Look at it on your first fill in a car you do not know.
- Good intentions do less than a sticker or a fob in a bright colour on your diesel's key when a home has one of each. So label it.
- Say it before you lift it. On your first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump. It seems silly and it works.
- Put your phone away. This is an easy mistake to make whilst you are thinking about something else.
- Some diesels come with a filler built to block 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 reading the petrol pump.
- As soon as you realise, stop: less petrol in the tank means a weaker mixture. What to do next doesn't change, though — still do not start it.
Everton: already put petrol in a diesel?
Then the order of things is short. Do not turn the ignition on, and don't crank it. If you are still on the forecourt — Shell or anywhere else — ask the attendants to help you roll the car clear of the pump. What got in, about how much, and whether it's run: tell us that when you call 0333 366 0103.
Corrosion and deposits form the issue with AdBlue, whereas petrol brings lost protection. So if it was AdBlue, say so — and see its own Everton page.
Everton petrol in a diesel tasks: why one costs more than another
An honest single price doesn't exist here: four situations, four separate tasks. Which of them you're in is mostly what shifts the cost. The ratio counts next, meaning how much of the tank is petrol, followed by the location of the car and whether getting to it is safe for our van.
That's why our technicians ask three questions before costing instead of after: what went in, how much, and whether it has run. Those replies are what turn a range into one firm number.
