Petrol in a Diesel Car in Pole Elm: How Worried Should You Be?
Probably less than you are now — provided no one has started the car. Until your ignition primes the pump, the starter cranks, or your car is driven, petrol in a diesel tank just rests there and does no harm. Which makes the honest reply to that first Pole Elm query — "have I wrecked it?" — usually no. To keep the vehicle that way, phone Petrol in Diesel and leave your motor switched off. Keep reading for three things: the effect petrol has inside a diesel engine, the clues of how far it has spread, and the way to make sure you never repeat it.
The motor and petrol in a diesel: what happens
On its way through a motor, diesel has two tasks. Oiling comes before burning; it does both. Made to very fine gaps, your injectors and the pump depend on the diesel moving through them to stop their surfaces wearing against one another.
Petrol handles the first task poorly and the second not at all. The rattling comes from petrol being made not to ignite when compressed, which is exactly the reverse of what a diesel needs. On top of that it is thinner than diesel, it strips away the protection the system rests on, and any pump running on that blend is wearing itself.
The shape of the issue is plain when you put those together. Not contact but movement is what does the harm. Any tank with petrol in it is a fuel fault. A pump that has been working 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.
Four scenarios our technicians see in Pole Elm: how bad is petrol in a diesel?
The best case there can be: filled up, not once started. Being at a forecourt is what makes this possible: elsewhere, the vehicle has been driven there to begin with. With the petrol held in the tank alone, it's cleared and rinsed on the spot, and nothing more is needed.
Started for a second, or only the ignition on. Petrol has come out of that tank and reached the fuel filter and the fuel lines, because the fuel system has been bled. Usually little more than clearing, purging and sorting the fuel filter, so still straightforward.
The pump has worked a couple of miles on weakened fuel — that is what driving it does. Distance is only half of it; how hard it was driven matters just as much. Either way this work includes that tank, your lines, the filter and clean fuel through the whole circuit. Short trips, like the school run to Callow End CofE Primary School, are one thing. Very different again: a trip to Worcester, under 5 miles away, or any distance on the M5, under 3 miles from Pole Elm, where the motor kept running hard.
Rattling, a ragged idle, smoke, a throttle gone soft: driven till it complained. The fuel is not acting like diesel any more, and your engine is saying so. Pull up on the spot — on the verge on Lower Ferry Lane, at the kerb, down a side road — and do not move it again. What goes first is still the fuel drain and flush-through, and that takes care of it, with lasting damage very unusual if a car is pulled over quickly.
Pole Elm motorists and that petrol in a diesel myths they hear
Myth: topping up to full with diesel makes it fine. It doesn't. Nothing is removed by topping up — you are left with a fuller tank, still the same mix. The assumption behind that guidance — that diesel fuel systems tolerate petrol by percentage — is wrong.
Myth: "A modern diesel can cope with a bit of petrol." If anything, the reverse. At higher pressure, through more precise parts: that is how a current diesel moves its fuel, and so the protection matters for more, not less.
Myth: "If it starts and drives, there's no harm done." This is the one that catches motorists. Diesel in a petrol motor normally leaves a motor that won't 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 will; meanwhile the pump grinds. Being able to run isn't proof of being fine.
Myth: "Add some two-stroke oil and drive the car home." It is an old fix for a different fault. It doesn't put back what petrol has weakened, and the petrol is still inside the tank after that.
"Drain it yourself and you are sorted" — a myth, because after it has been running some petrol lies in the filter and lines, waiting to go right back through the pump on the next start. On top of that, petrol cleared into a can by the road is truly dangerous.
How does petrol in a diesel take place?
It's rarely carelessness, and no one does it on purpose. One way only, since of the nozzles: the smaller petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one generally will not fit a petrol motor. That's how the forecourt makes it simple.
The moment routine stops matching the vehicle is the moment it happens. Courtesy car, hire car, or a vehicle that's brand new. One petrol and one diesel on the driveway of the same household. A well-known forecourt with the pumps in a different order. Filling up in a rush on the way to Worcester Foregate Street, with a train to catch. Years of petrol motors behind you, a diesel Volkswagen Golf in front of you on the forecourt for its first tank — that's when. Throw in rain, a phone call or a back seat full of children, and your hand repeats what it has always done.
How to prevent petrol in a diesel on your next fill-up around Pole Elm
- The label is what counts, and so read the 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. Plenty of cars state the fuel inside the flap or on the cap. Look at it on your first fill in a car you do not know.
- One of each in the household? Label your key to the diesel — a coloured fob, a sticker — since intending to remember isn't enough.
- Before the nozzle leaves the pump the first time you fuel a hired or new vehicle, say "diesel" out loud. Daft, yes, yet it works.
- Put your phone away. This is an easy mistake to make whilst you are thinking about something else.
- Add-on devices are available for motors without one, and some diesels come with a filler that will not accept a petrol nozzle. Helpful — but a backstop at best, never a reason to stop checking the label.
- Less petrol means a weaker mix, so stop the moment you notice — while remembering that your next step is unchanged. It's still not to crank it.
Pole Elm: already put petrol in a diesel?
Then the order of things is short. Starting it is out, and so is turning on your ignition. The staff at the forecourt — whether at JET itself or wherever you filled up — will normally help roll it clear of the pump if you ask. Then ring 0333 366 0103 and tell us what got in, about how much, and if it has run.
Say so if it was AdBlue rather than petrol: it's a different problem, with its own page for Pole Elm, because AdBlue brings corrosion and deposits instead of lost protection.
Pole Elm petrol in a diesel tasks: why one costs more than another
There's no honest single price for this, because the four scenarios above are four different tasks. Which of them you're in is mostly what shifts the cost. Two things come after that: the petrol that was put in as a share of what your tank takes, then the place your car is in and whether our van can reach it safely.
Ahead of any quote, not after, we ask three questions: your fuel that was put in, its amount, and whether it has run. That is why. A range turns into a straight figure when those answers are in.
