Petrol in a Diesel Car in Westcourt: How Worried Should You Be?
Unstarted? Then less anxious than you probably are. Till your ignition primes the pump, your starter turns, or the car is driven, petrol in a diesel tank simply waits there and does no harm. Which makes the truthful reply to the first Westcourt query — "have I wrecked it?" — normally no. Keep it that way: leave your motor off and call Petrol in Diesel. Below, you will find what petrol really does inside a diesel, how far it might have got, and how to stop it happening to you a second time.
Inside the engine: what petrol in a diesel does
Passing through an engine, diesel is doing two things at the same time. It protects to begin with, and after that does it burn. Extremely fine tolerances are built into the injectors and the high-pressure fuel pump, and just your diesel flowing through stops those surfaces grinding together.
Petrol does the first job badly and the second not at all. It is runnier than diesel and takes away the lubrication the system rests on, and 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 is where the clattering comes from.
The shape of the trouble is clear when you put those together. It's circulation that causes the harm, not contact. Petrol in a tank is a fuel fault. 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 the injectors further on.
Petrol in a diesel around Westcourt: how bad is it? Four cases
Filled but never started — the best it gets. That petrol is in the tank and just your tank, and the job is a drain and a flush where your car stands. This is the one situation that can only really take place at a forecourt, as anywhere else your car has been driven to get there.
A brief spell of running, or merely the ignition on. With the system primed, your lines and filter now contain petrol that came from that tank. That's usually still a straightforward task — a drain, a flush, and the filter dealt with.
The pump now spent a few miles on diluted fuel — that is what driving it does. How hard the car was driven counts as much as how far, and the work covers your tank, the fuel lines, your filter and clean fuel through the whole circuit. Driving the children to Westcourt Primary School is one kind of trip. Very different again: a trip to Southend-on-Sea, under 25 miles away, or any miles on the M2, under 3 miles from Westcourt, where the motor kept running hard.
It complained, and only then stopped: smoke, knocking, a throttle gone soft, an idle gone uneven. That's your motor telling you its fuel has stopped acting like diesel. Pull up wherever you are — the verge on Hillside Avenue, a lay-by, a side street — and leave the car where it is. Long-term damage is very rare when a car is stopped quickly, and the drain and flush that still come first deal with it.
Myths Westcourt drivers hear about petrol in a diesel
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. A diesel fuel system does not tolerate petrol by percentage in the way that advice presumes.
Myth: "A current diesel can cope with a bit of petrol." If anything, the opposite. At higher pressure, through finer components: that's how a current diesel moves its fuel, and so the lubrication matters for more, not less.
The myth that catches motorists off guard: if it starts and drives, it must be unharmed. The motorist of a petrol motor fed diesel usually stops, since it will not run, and the damage stops with them. While your pump grinds, a diesel fed petrol usually starts, idles and drives away as though nothing has happened. Running isn't the same as fine.
Myth: "Add some two-stroke oil and drive it home." It is an outdated fix for a separate fault. None of what petrol weakened is put back by it — and afterwards, the tank still holds the petrol.
If the engine has been run, part of the petrol sits in the fuel filter and the fuel lines, not that tank — and your next start sends it right back through the pump. So the myth "drain the tank yourself and you are sorted" doesn't hold. And, a can of petrol drained by the kerbside is genuinely dangerous.
Petrol in a diesel: how does it take place?
Nobody does it on purpose, and it is seldom carelessness. One way only, because of the nozzles: the slimmer petrol one slips inside a diesel filler with almost no resistance, while the diesel one mostly will not fit a petrol vehicle. That's how the forecourt makes it simple.
It occurs when habit and the car stop matching. Any vehicle that is new to you — hired, on loan as a courtesy car, or just bought. A household with one petrol and one diesel on the driveway. Your ordinary forecourt, its pumps suddenly in a different order. Fuelling up in a rush on the way to Gravesend, with a train to catch. Years of petrol cars behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when. Add a back seat full of kids, a phone call or rain, and habit takes over.
Westcourt people: how to prevent petrol in a diesel next time
- Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most usually do. Read the petrol pump's label; the colour is just a hint.
- In a vehicle you do not know, look inside the flap over the filler or at the cap before the first fill: plenty of cars state the fuel type there.
- One of each in the house? Label the key to your diesel — a coloured fob, a sticker — because meaning to remember is not enough.
- Before the nozzle leaves the petrol pump the first time you fill a hired or new vehicle, say "diesel" out loud. Daft, perhaps, yet it works.
- Mistakes like this are simple to make whilst your mind is on something else, so your phone goes away.
- A misfuel inhibitor helps, up to a point. Some diesels come with a filler designed to reject a petrol nozzle, and add-on devices are available for motors without one. They are a safety net, not a reason to stop checking the petrol pump.
- Less petrol means a weaker mixture, and so stop as soon as you realise — while remembering that the next stage is unchanged. It is still not to fire it up.
Put petrol in a diesel around Westcourt already?
The order of things is brief, then. Leave it unstarted, with your ignition off too. Ask the attendants to help you roll it away from the pump if you're still on the forecourt, whether that is Esso or anywhere else. Then phone 0333 366 0103 and tell us what went in, about how much, and whether it's run.
Corrosion and deposits are the issue with AdBlue, whereas petrol means lost lubrication. So if it was AdBlue, say so — and read its own Westcourt page.
Why one petrol in a diesel task in Westcourt costs more than another
The four scenarios above are four different tasks, so no single price for this would be fair. The scenario itself does most of the work of moving your cost. The ratio counts next, meaning how much of that tank is petrol, followed by the location of your car and whether reaching it is safe for a van.
Three questions come first, before quoting, rather than after — what was put in, how much, has it run — and that is the reason. A range becomes a straight figure once those replies are in.
