Rushington: Petrol in a Diesel Car? How Worried to Be
Provided it has not been started, you can worry far less than you likely are. Petrol resting in a diesel tank does nothing to your motor till something pulls it through the system — the ignition priming the pump, your starter, or the drive itself. So the fair answer to the first question everyone in Rushington asks, "have I wrecked it?", is generally no. To keep it that way, ring Petrol in Diesel then leave your motor switched off. 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.
What petrol in a diesel does to the motor
Two jobs fall to diesel on its route round a motor. It protects first, and only then does it burn. The high-pressure pump and your injectors are designed to very fine clearances, and your diesel passing through them is what stops those surfaces from wearing against one another.
Of these two jobs, petrol handles the first poorly and the second not at all. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, so a pump running on the blend to wear itself. It's also made to resist igniting under compression — the opposite of what a diesel needs — which is why you hear the rattling.
Seen together, they make clear the shape the trouble has. Contact does not do the harm — movement does. All a tank with petrol in it amounts to is a fuel fault. A pump that has been running on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with the fuel to the fuel injectors further on.
Rushington, petrol in a diesel: four cases, from mild to serious
The best case there can be: filled up, not once started. That petrol is in your tank and only that tank, and the job is a drain and a flush where the car stands. This is the one scenario that can only really occur at a forecourt, as anywhere else the vehicle has been driven to get there.
Started for a moment, or just the ignition on. Once primed, the fuel system has drawn petrol out of the tank up to the filter and the lines. Normally little more than draining, cleaning and seeing to the filter, so still simple.
Driven a few miles. Now your pump has spent those miles working on thinned fuel. The work is the tank, the fuel lines, the fuel filter and clean fuel through the entire system, and how hard the car was driven counts as much as how far. Driving the kids to Lydlynch Infant School is one sort of trip. Any miles on the Nursling Spur Motorway, under 3 miles from Rushington, means the engine working hard throughout, and a run to Southampton, under 5 miles away, is a very different task as well.
Knocking, an uneven idle, smoke, a throttle gone soft: driven till it complained. The fuel is not acting like diesel any more, and the motor is saying so. Stop where you are — on the verge on Rushington Lane, at the kerb, down a side road — and do not move it. Permanent damage is very unusual when a car is stopped quickly, and the fuel drain and flush-through that still go first sort it out.
Petrol in a diesel myths Rushington motorists hear
"Top it up the rest of the way with diesel and it will be fine" — a myth. It will not. A fuller tank of the same mix is all you get, because topping up removes nothing. Percentage is not how a diesel fuel system tolerates petrol, whatever that advice supposes.
If anything, the opposite is true. Myth: "A newer diesel can cope with a bit of petrol." At higher pressure, through finer parts: that's how a newer diesel moves its fuel, so the lubrication counts more, not less.
"It starts, it drives, and so no harm done" — the myth that trips up more motorists than any other. The motorist of a petrol engine fed diesel usually stops, since it will not run, and the harm stops with them. A diesel fed petrol generally starts, idles and drives away as though nothing has happened, whilst your pump grinds. Running isn't the same as fine.
Myth: a two-stroke additive makes it safe to drive home. It is an old workaround, supposed for another fault. It doesn't put back what petrol has weakened, and the petrol is still in that tank afterwards.
"Drain it yourself and you are sorted" — a myth, because after it's been running some petrol lies in the fuel filter and lines, waiting to go right back through the pump at your next start. Emptying petrol into a can by the roadside is also really risky.
Why petrol in a diesel occurs so easily
On purpose? Never. Through carelessness? Seldom, if ever. The petrol nozzle is the smaller of the two and slides into a diesel filler with almost no resistance; a diesel nozzle generally won't go into a petrol motor at all. The forecourt makes it simple, and the error runs one way.
Habit and your car getting out of step is when it takes place. A new car, a hire car or a courtesy car. A household with one petrol and one diesel on the driveway. A forecourt you know, but with its pumps laid out differently. A train to catch, and a hurried fill en route to Totton. Years of petrol motors behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when. The hand repeats what it has always done when you add rain, a phone call or a back seat full of kids.
Next time you fill up around Rushington: preventing petrol in a diesel
- The label is what counts, so check the petrol pump rather than the colour: in the UK unleaded handles are usually green and diesel black, yet not on each forecourt.
- Inspect the filler flap. Plenty of motors state the fuel inside the flap or on the cap. Look at it on your first fill in any motor you do not know.
- A coloured fob or a sticker on your diesel's key achieves more than any amount of meaning to remember, for a house with one of each.
- It seems daft and it does the trick: on your first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump.
- Thinking about something else is when this becomes an easy mistake to make, and so tuck your phone away then keep your mind on the pump.
- Some diesels have a filler built to reject a petrol nozzle, and devices you can add exist for cars without one. Such an inhibitor helps up to a point — as a backstop, not a reason to stop checking the petrol pump.
- The moment you realise, stop: less petrol in your tank makes a weaker mix. What to do next doesn't change, though — still don't crank it.

Then, there is just a short order of things. Never start the car, and do not turn the ignition on. If you are still on the forecourt — Esso or anywhere else — ask the attendants to help you push it away from the petrol pump. Then call 0333 366 0103 and tell us what went in, about how much, and if it has run.
Corrosion and deposits are the problem with AdBlue, whereas petrol brings lost lubrication. So if it was AdBlue, say so — and read its own Rushington page.
What makes one Rushington petrol in a diesel job cost more than the next
The four scenarios above are four separate jobs, so no single price for this would be honest. The scenario itself does most of the work of moving your cost. After that it is the proportion — how much petrol was put in against how much the tank holds — and then where the vehicle is and whether our van can reach it safely.
What went in, how much, and if it has run — three queries our technicians ask before quoting, not after, for precisely that reason. Those answers are what turn a range into one firm number.
