Should You Worry? Petrol in a Diesel Car in East Malling Heath
If it hasn't been started, worry less than you probably are. Till the ignition primes your pump, the starter turns, or your car is driven, petrol in a diesel tank simply rests there and does no harm. Which makes the truthful reply to the first East Malling Heath query — "have I wrecked it?" — usually no. To leave the car that way, ring Petrol in Diesel then leave your motor switched off. Keep reading for three things: the effect petrol has inside a diesel motor, the clues of how far it has got, and ways to make sure you never do it again.
Inside your engine: what petrol in a diesel does
On its way through an engine, diesel does two jobs. Lubricating comes before burning; it does both. Your high-pressure pump and the fuel injectors are designed to extremely fine gaps, and the diesel passing through them is what keeps those surfaces from wearing against one another.
Badly at the first, not at all at the second: that's petrol. The rattling comes from petrol being designed 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 away the protection the fuel system depends on, and any pump running on such a mixture is wearing itself.
The shape of the trouble is plain when you put those together. It's movement that causes the harm, not contact. Any tank with petrol in it is a fuel issue. After the pump has been running on that petrol, a mechanical issue has started: whatever is shed by a pump that is wearing down is carried onward to the fuel injectors with your fuel.
How bad is petrol in a diesel? Four scenarios we see around East Malling Heath
Filled up, and never started: nothing beats it. At a forecourt, and genuinely only there, the petrol is still confined to your tank — since everywhere else the vehicle was driven to reach it. The job is emptying and rinsing on the spot.
A brief spell of running, or merely your ignition on. Petrol has come out of your tank and reached your filter and the lines, since the system has been primed. Still usually easy: drain, flush, and your filter dealt with.
The pump has worked a couple of miles on weakened fuel — that is what driving it does. The work is the tank, the fuel lines, the fuel filter and clean fuel through the whole circuit, and how hard the vehicle was driven counts as much as how far. The school run to The Discovery School is one thing. Any miles on the M20, under 3 miles from East Malling Heath, means your engine working hard throughout, and a run to Southend-on-Sea, under 25 miles away, makes a very different job too.
Driven on until it complained — knocking, smoke, a ragged idle, a soft throttle. The fuel isn't acting like diesel any more, and your motor is saying so. Whether it's the verge on Wateringbury Road, a lay-by or a side road, stop where you are then leave it. A car stopped soon very rarely has permanent damage, because the drain and the flush-through, which still come first, take care of it.
Petrol in a diesel stories East Malling Heath motorists hear
It will not be fine. The myth: "Fill it the rest of the way with diesel and it'll be." Nothing is removed when you top up — that tank just carries more of the same blend. That advice supposes a diesel fuel system handles petrol by percentage. It does not.
Myth: "A newer diesel can cope with a bit of petrol." If anything, the opposite. At higher pressure, through more precise components: that is how a modern diesel handles its fuel, so the lubrication counts for more, not less.
This is the one that catches drivers. Myth: "If it starts and drives, there's no damage done." The motorist of a petrol motor fed diesel normally stops, since it will not run, and the damage stops with them. Whilst your pump grinds, a diesel fed petrol normally starts, idles and drives away as though nothing has happened. Fine and running are not the same thing.
Myth: "Add some two-stroke oil and drive it home." It is an outdated workaround for a separate issue. It does not put back what petrol has weakened, and the petrol is still in the tank later.
Myth: "Drain the tank yourself and you're sorted." Once the motor has run, some of that petrol is no longer inside that tank: it is in the fuel filter and the lines, and it goes straight back through your pump on the next start. And, a can of petrol drained at the kerbside is truly risky.
Petrol in a diesel: how does it happen?
Carelessness is rarely the cause, and no one means to do it. A diesel nozzle mostly will not go into a petrol vehicle, yet the smaller petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one error easy, and only in one direction.
Routine and the car falling out of step is when it happens. Hire cars, courtesy cars, and motors that are new to you. Households running one of each, petrol and diesel. Your usual forecourt, its pumps suddenly in a different order. A rushed fill on the way to East Malling with a train to catch. Precisely the moment it takes place: after years of driving petrol, someone fills a diesel Volkswagen Golf for the first time. Add a back seat full of kids, a phone call or rain, and the hand takes over.
Preventing petrol in a diesel next time you fill up in East Malling Heath
- Green for unleaded and black for diesel is normal in the UK — but not on every forecourt. Trust the label on the petrol pump, not the colour.
- Check your filler flap. Plenty of motors state the fuel inside the flap or on the cap. Look at it on your first fill in a car you don't know.
- One of each in the house? Label the key to your diesel — a bright fob, a sticker — since intending to remember is not enough.
- "Diesel", out loud, before you pick up the nozzle — every time a new or hired car gets its first tank. It seems silly. It works.
- Thinking about something else is when this becomes an easy mistake to make, and so put the phone away then keep your mind on the pump.
- Some diesels have a filler designed to refuse a petrol nozzle, and devices you can add are available for cars without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop checking the petrol pump.
- Noticing it halfway? Stop there and then. A thinner mixture results from less petrol in your tank, but your next stage remains the same: do not crank it.
Put petrol in a diesel around East Malling Heath already?
In that case, there is just a short order of things. Starting it is out, and so is switching on the ignition. Yet on the forecourt, at JET or anywhere else? Ask the staff to help you push the car clear of the petrol pump. What was put in, about how much, and if it has run: tell us those when you phone 0333 366 0103.
If it was AdBlue and not petrol, say so. That's a separate fault — corrosion and deposits rather than lost protection — and it has its own page for East Malling Heath.
Why one petrol in a diesel job around East Malling Heath costs more than another
Four different tasks lie behind the four situations above — which is why there is no fair single quote. What shifts the cost is mostly which of them you are in. Beyond that it's the share — how much petrol was put in against how much that tank holds — and after that where the car is and whether a van can reach it safely.
That's why we ask three queries before quoting instead of after: what went in, how much, and whether it has run. Those replies are what turn a range into one firm number.
