Should You Worry? Petrol in a Diesel Car in Lower Popeley
Probably less than you already are — as long as nobody has started it. "Have I wrecked it?" is the first question anyone in Lower Popeley asks, and the honest answer is normally no, since petrol left in a diesel tank hurts nothing till it's dragged through the system — by ignition priming, by your starter, or by being driven. To keep it that way, ring Petrol in Diesel and leave the engine alone. The remainder of this page covers what petrol actually does to a diesel, how to tell how far it has got, and how to make sure it doesn't happen to you a second time.
The motor and petrol in a diesel: what happens
Passing through an engine, diesel does two jobs at once. It lubricates to begin with, and after that does it burn. Your high-pressure pump and the fuel injectors are designed to very fine gaps, and the diesel passing through them is what stops those surfaces from wearing down against each other.
The second task petrol doesn't do at all, and the first it does badly. It's runnier than diesel and takes away the lubrication your fuel system hinges on, so a pump running on a petrol mix is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That's where the clattering comes from.
Combined, those leave the shape of the trouble plain. The damage is done by circulation, not by 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 start of a mechanical one, and whatever a worn pump sheds travels on with your fuel to your injectors downstream.
How serious is petrol in a diesel? Four situations our engineers see in Lower Popeley
The best case there is: filled up, not once started. Just your tank has petrol in it, and so the job is clearing your tank and cleaning the system where your car sits. This situation can only truly happen at a forecourt: anywhere else, the car got there by being driven.
Your ignition turned on, or a short start. Petrol has come out of the tank and got to the fuel filter and your lines, since the system has been primed. Usually nothing more than clearing, purging and sorting your filter, and so still straightforward.
Some miles driven, and your pump has spent each of them working on diluted fuel. Miles is only half of that; how hard it was driven counts equally. Either way this work runs to that tank, the lines, the filter and clean fuel through the whole system. On the school run to Millbridge, A Share Primary Academy, the mileage is small. Very different a second time: a run to Bradford, under 10 miles away, or some miles on the M62, under 3 miles from Lower Popeley, where the motor kept labouring hard.
It protested, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone lumpy. That's your engine telling you its fuel no longer is acting like diesel. Whether it is the verge on Fieldhead Way, a lay-by or a side road, stop where you are and leave it. A vehicle pulled over soon very seldom has lasting damage, since the drain and the flush-through, which still come first, sort it out.
Lower Popeley drivers and that petrol in a diesel myths they hear
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 — your tank simply carries more of the same blend. That advice assumes a diesel fuel system tolerates petrol by percentage. It doesn't.
If anything, the opposite holds. Myth: "A newer diesel can cope with a bit of petrol." At higher pressure, through finer components: that is how a modern diesel handles its fuel, so the lubrication matters more, not less.
"It starts, it drives, and so no harm done" — the myth that trips up more drivers than any other. Diesel in a petrol motor generally means a motor that will not run: the motorist stops, and so does the harm. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually does; meanwhile your pump wears. Running isn't the same as fine.
Myth: a two-stroke additive lets you to drive home. It was an old workaround, supposed for another problem. What petrol has weakened remains thinned, and that petrol stays in your tank regardless.
Myth: "Drain that tank yourself and you are sorted." Once the engine has been run, some of that petrol is no longer in your tank: it's in your filter and the fuel lines, and it goes right back through your pump on your next start. And, a can of petrol filled by the roadside is genuinely risky.
Petrol in a diesel: how does it occur?
On purpose? Never. Through carelessness? Rarely, if ever. One way only, because of the nozzles: the smaller petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one mostly won't fit a petrol motor. That's how the forecourt makes it straightforward.
The moment routine stops matching the car is the moment it happens. A new motor, a hire car or a courtesy car. Two motors on one driveway, one petrol, one diesel. A forecourt you know, only with its pumps arranged differently. A rushed fill on the way to Batley with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a driver used to petrol: exactly when it takes place. With rain, a call coming in, or children to deal with, your hand simply does what it always has.
Lower Popeley people: how to prevent petrol in a diesel next time
- The label is what counts, so read the petrol pump rather than the colour: in the UK unleaded handles are usually green and diesel black, yet not on every forecourt.
- Inspect your filler flap. Many vehicles state the fuel inside the flap or on the cap. Look at it on the first fill in any motor you don't know.
- One of each in the house? Label your key to the diesel — a bright fob, a sticker — because intending to remember is not enough.
- It sounds daft and it works: on the first fill in a new or hired car, say "diesel" out loud before you lift the nozzle off the petrol pump.
- Mistakes like this are straightforward to make whilst your mind is on something else, and so your phone goes away.
- A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to refuse a petrol nozzle, and add-on devices are available for vehicles without one. They are a safety net, not a reason to stop checking the pump.
- The moment you notice, stop: less petrol inside your tank makes a weaker mix. What to do next doesn't change, though — still do not fire it up.
Lower Popeley: already put petrol in a diesel?
Short and simple, then, is the order of things. Don't switch your ignition on, and don't start it. Ask the attendants to help you push it clear of the pump if you're still on the forecourt, whether that is Texaco or anywhere else. Next, 0333 366 0103. We'll ask what went in, roughly how much, and if it has been run.
AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a separate problem — Lower Popeley has a page just for it.
Why one petrol in a diesel job around Lower Popeley costs more than another
There is no honest single quote for this, since the four scenarios above are four separate tasks. Chiefly, your cost shifts with which one you are in. Where the vehicle is counts too, and whether our van can safely get to it, after the ratio of petrol to what the tank holds.
What went in, how much, and whether it has run — three questions our engineers ask before costing, not after, for precisely that reason. A range turns into a straight figure once those replies are in.
