Rickleton: Petrol in a Diesel Car? How Worried to Be
Far less than you likely are, provided it has not been started. "Have I wrecked it?" is the first thing anyone around Rickleton asks, and the honest answer is generally no, since petrol left in a diesel tank hurts nothing until it's drawn through the system — by ignition priming, by your starter, or by driving. Leave the motor off and call Petrol in Diesel — that is how you keep it that way. 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 a second time.
What petrol in a diesel does to the engine
Diesel has two tasks on its way through a motor. Before it ignites, it protects — and then it ignites. Your high-pressure pump and the fuel injectors are designed to very fine clearances, and the diesel passing through them is what keeps those surfaces from grinding against one another.
Badly at the first, not at all at the second: that is petrol. Being less viscous than diesel, petrol strips away the lubrication a fuel system needs, so a pump on the blend to wear itself. It is equally made to resist igniting under compression — the reverse of what a diesel needs — which is where you hear the rattling.
Taken together, they show the shape the trouble has. Contact doesn't do the damage — movement does. Petrol in the tank is a fuel fault. After the pump has been working on that petrol, a mechanical issue has begun: anything shed by a pump that is grinding is carried downstream to the fuel injectors with the fuel.
Petrol in a diesel in Rickleton: how serious is it? Four cases
Filled but not once started — the best it gets. Being on a forecourt is what makes this the case: elsewhere, the vehicle has been driven there to begin with. With that petrol held in your tank alone, it's emptied and flushed on the spot, and nothing more is needed.
Started for a second, or just your ignition on. With the system primed, your lines and filter now contain petrol that has come from that tank. That's generally still a simple job — a drain, a flush, and the filter seen to.
Driven a few miles. Now your pump has spent these miles running on diluted fuel. Tank, lines, filter, then fresh fuel run through the entire system: that's this work, and the way the vehicle was driven matters as much as the distance. A school run to Rickleton Primary School is one matter. Very different again: a trip to Sunderland, under 10 miles away, or any mileage on the Western Highway, under a mile from Rickleton, where the motor never stopped working hard.
Driven till it complained. Clattering, an uneven idle, smoke, a throttle that has gone soft. That is the motor telling you its fuel has stopped acting like diesel. Stop on the spot — on the verge on The Chase, at the kerb, down a side road — and do not move it again. Permanent damage is very uncommon when a vehicle is stopped early, and the drain and flush-through that still come first sort it out.
What Rickleton people get told about petrol in a diesel — and the myths in it
"Top it up the rest of the way with diesel and it will be fine" — a myth. It won't. Nothing is removed when you top up — your tank simply carries more of the same blend. The assumption behind the advice — that diesel fuel systems accept petrol by percentage — is wrong.
"Current diesels can handle a little petrol" — a myth, and closer to the opposite. A current diesel runs its fuel through more precise components at higher pressure, which makes the protection matter more, not less.
This is the one that catches motorists. Myth: "If it starts and drives, there's no damage done." Any petrol motor fed diesel normally will not run, so the driver stops and the harm stops with them. A diesel fed petrol generally starts, idles and drives away as though nothing has happened, whilst the pump wears. Fine and running are not the same at all.
Myth: "Add some two-stroke oil and drive it home." It's an outdated workaround for a different fault. The petrol is still in your tank afterwards, and what it has thinned isn't put back.
Myth: "Drain the tank yourself and you are sorted." Once the motor has been run, some of the petrol is no longer in that tank: it's in the filter and your lines, and it goes straight back through your pump on your next start. And, a can of petrol drained at the kerbside is truly risky.
How petrol ends up: petrol in a diesel
On purpose? Never. Through carelessness? Rarely, if ever. A diesel nozzle mostly won't go into a petrol motor, but the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake straightforward, and only in one direction.
Routine and the vehicle falling out of step is how it occurs. A new motor, a hire car or a courtesy car. Households running one of each, petrol and diesel. A familiar forecourt with the pumps in a different order. Rushing for a train outside Chester-Le-Street and filling up en route. Years of petrol motors behind you, a diesel Renault Megane in front of you on the forecourt for its first tank — that is when. Your hand repeats what it has always done once you add rain, a phone call or a back seat full of kids.
Rickleton people: how to avoid petrol in a diesel next time
- Read the petrol pump, not the colour. In the UK unleaded handles are usually green and diesel black, but not on every forecourt. The label is what matters.
- In a vehicle you do not know, look inside the flap over the filler or at the cap before the first fill: plenty of motors state the fuel there.
- Mark your key. In a home with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of intending to remember.
- It sounds silly and it does the trick: on your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the pump.
- While you are thinking about something else, this is an easy mistake to make — so tuck your phone away.
- A misfuel inhibitor helps, up to a point. Some diesels come with a filler designed to block a petrol nozzle, and add-on devices are available for cars without one. They are a safety net, not a reason to stop reading the petrol pump.
- As soon as you notice, stop: less petrol inside that tank makes a weaker mixture. What to do next does not change, though — still don't fire it up.
Rickleton: already put petrol in a diesel?
The order of things is brief, then. Starting it is out, and so is turning on your ignition. Yet at the forecourt, at BP or anywhere else? Ask the staff to help you push the vehicle away from the petrol pump. Next, 0333 366 0103. We will ask what got in, roughly how much, and if it has been run.
Corrosion and deposits are the trouble with AdBlue, where petrol means lost protection. So if it was AdBlue, say so — and see its own Rickleton page.
One petrol in a diesel task around Rickleton costs more than another. Why?
Four different tasks lie behind the four scenarios above — which is why there is no honest single quote. Mostly, your cost moves with which situation you're in. Two things follow that: the petrol that got in as a share of what that tank takes, then the spot the vehicle is in and whether a technician can reach it safely.
What was put in, how much, and if it's run — three questions our engineers ask before costing, not after, for precisely that reason. A range becomes a straight figure once the answers are in.
