Should You Worry? Petrol in a Diesel Car in Clayton Hill
Provided it has not been started, you can worry far less than you probably are. Petrol resting in a diesel tank does nothing to your motor until something pulls it through the system — the ignition priming your pump, the starter, or driving itself. So the honest answer to the first query everyone in Clayton Hill asks, "have I wrecked it?", is generally no. To leave the car that way, ring Petrol in Diesel then leave your engine switched off. The remainder of this page explains what petrol actually does to a diesel, how to judge how far it has got, and how to make sure it doesn't happen to you a second time.
Petrol in a diesel: what does it do to the motor?
On its way through a motor, diesel has two tasks. It ignites, and before it burns it lubricates. What keeps the surfaces inside the high-pressure fuel pump and the fuel injectors from wearing against one another is the diesel flowing through them — they are built to extremely fine gaps.
Badly at the first, not at all at the second: that's petrol. It's runnier than diesel and takes away the lubrication your fuel system rests on, so a pump running on a petrol mix is a pump wearing itself. And petrol is made to resist igniting under compression, which is the opposite of what a diesel needs from its fuel. That is where the clattering comes from.
Taken together, they show the shape the trouble takes. It's circulation that does the harm, not contact. Any tank with petrol in it is a fuel issue. The start of a mechanical one is a pump that has been running on that petrol — and whatever a worn pump sheds moves on with the fuel to your injectors beyond it.
Clayton Hill, petrol in a diesel: four cases, from mild to major
The best case there is: filled up, not once started. At a forecourt, and really only there, the petrol is still confined to that tank — because everywhere else the vehicle was driven to reach it. The job is emptying and cleaning on the spot.
Ignition on, or started for a second. Once primed, your system has drawn petrol from the tank up to the fuel filter and the lines. That is generally still a simple task — a drain, a flush, and the filter dealt with.
Those few miles on the road were the pump working on fuel diluted by petrol throughout. How hard your car was driven counts as much as how far, and this work covers the tank, the lines, the fuel filter and clean fuel through the entire system. Driving the kids to Wakefield Lawefield Primary School is one kind of trip. A run as far as Wakefield, under a mile away, is a very different job. So is any distance on the M1, under 3 miles from Clayton Hill, where the motor has been labouring hard throughout.
Rattling, an uneven idle, smoke, a throttle gone soft: driven till it complained. What you are hearing is your engine reporting fuel that no longer behaves like diesel. Leave it where it stops: a lay-by, a quiet street, the verge on Claremont Terrace. A car stopped soon very rarely has permanent damage, since the fuel drain and the flush-through, which still go first, deal with it.
Clayton Hill drivers and that petrol in a diesel myths they hear
"Top it up the rest of the way with diesel and it'll be fine" — a myth. It will not. Nothing comes out when you top up — that tank just holds more of the same mixture. That guidance supposes a diesel fuel system tolerates petrol by percentage. It does not.
Not so: a current diesel copes with a bit of petrol. If anything, the opposite. Protection matters more on newer diesels, not less, because their fuel passes through smaller components at higher pressure.
"It starts, it drives, and so no harm done" — the myth that trips up most drivers than any other. The motorist of a petrol engine fed diesel normally has no choice but to stop, since it will not run, and the damage stops with them. A diesel fed petrol generally starts, idles and drives away as if nothing has happened, while your pump wears. Running is not the same as fine.
Myth: "Add some two-stroke oil and drive the car home." It is an outdated workaround for a separate fault. What petrol has thinned stays diluted, and the petrol stays inside the tank regardless.
The next start sends petrol back round the pump from the fuel lines and the filter, where some of it sits once your engine has been run. That's why draining the tank yourself does not leave you sorted — a myth. It's also genuinely hazardous to drain petrol into a can by the roadside.
How petrol ends up: petrol in a diesel
On purpose? Never. Through carelessness? Seldom, if ever. A diesel nozzle mostly will not go into a petrol vehicle, yet the slimmer petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake straightforward, and only in one direction.
Habit and your car getting out of step is how it occurs. A new motor, a hire car or a courtesy car. One petrol and one diesel on the drive of the same household. Your ordinary forecourt, its pumps suddenly in a different order. Rushing for a train at Wakefield Westgate and filling up en route. Precisely the moment it happens: after years of driving petrol, someone fills a diesel Volkswagen Golf for the first time. Throw in a back seat full of children, a phone call or rain, and the hand takes over.
How to avoid petrol in a diesel at your next fill-up in Clayton Hill
- Read the petrol pump, not the colour. In the UK unleaded handles are usually green and diesel black, but not on each forecourt. The label is what counts.
- Plenty of motors state the fuel type inside the filler flap or on the cap, and so check there on your first fill in a motor you do not know.
- Label your key. In a household with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember.
- It seems silly and it works: on your first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the petrol pump.
- While you are thinking about something else, this is an easy mistake to make — so put the phone away.
- Up to a point, a misfuel inhibitor helps: some diesels come with a filler built to block a petrol nozzle, and add-on devices are available for the rest. Treat it as a safety net, then keep checking the pump.
- The moment you notice, stop: less petrol inside your tank means a weaker blend. What to do next does not change, though — still don't fire it up.

Short and simple, then, is the order of things. Never fire it up, and don't turn the ignition on. Ask the attendants to help you roll it away from the petrol pump if you're still at the forecourt, whether that's Sainsbury's or somewhere else. Next, 0333 366 0103. We will ask what got in, about how much, and if it has been run.
Corrosion and deposits form the trouble with AdBlue, whereas petrol means lost protection. So if it was AdBlue, say so — and see its own Clayton Hill page.
One petrol in a diesel task around Clayton Hill costs more than another. Why?
Four separate tasks sit behind the four situations above — which is why there is no fair single price. What shifts your cost is chiefly which of them you are in. Two things follow that: the petrol that was put in as a share of what the tank takes, then the spot your car is in and whether our van can reach it safely.
What was put in, how much, and if it's run — three questions we ask before pricing, not after, for exactly that reason. Given those answers, there is a straight figure rather than a range.
