Side of the Moor: Put Petrol in a Diesel Car?
If you have not fired up your engine yet, don't. A drain and nothing else is almost always what a motor needs while the fuel is still inside the tank and your engine has not yet turned over, which is why it's the coming few minutes that count, not how much got in. Petrol in Diesel comes to the car wherever it has stopped in Side of the Moor or the remainder of Greater Manchester, on the forecourt, by the roadside or on a driveway, and drains and cleans it there. A single call our way will be enough: our team can show you what comes from here. Try that first.
Petrol in a diesel: what to try next
- Whenever you drive, your pump and the fuel injectors wear. This is why you don't fire it up, and why you don't depend on it once it has started. The thing about petrol in a diesel especially — the part motorists get wrong — is that it drives away normally for the first mile or two. Diesel in a petrol engine usually cannot run at all, which stops the driver and stops the harm with them. This one lets you drive on.
- Leave the car's ignition off also. Diesel does two tasks: it combusts, and before it combusts it lubricates your high-pressure fuel pump and those injectors. Petrol handles the first and not the second. Turning your ignition on is frequently enough to prime your system, which draws this petrol out of the tank then into just those components.
- That guidance presumes a diesel fuel system tolerates petrol by percentage. It doesn't. Add diesel on top and nothing at all is taken out; what you get is a bigger tank of the same mix. And no, the type makes no difference — super unleaded is still petrol.
- We'd sooner drive to a difficult place than have it started — so if you sensibly can, sit tight. Nothing is easier to deal with than a vehicle that has not moved. On the verge on Riding Gate Mews, that means hazards on then leave it.
- Before you dial, get your whereabouts. Anything closest to you with a name on it, plus a postcode starting BL2 4 — that is what decides whether the van shows up or circles.
- Three replies settle the entire visit: the stuff you poured in, the approximate volume involved, plus if it has been turning since. Our number is 0333 366 0103.
Quarter past eight. A hurried fill-up on the trip in. At about eleven it occurs to you, and by then your diesel Volkswagen Passat has sat at Bromley Cross for three hours. Ring us and keep it where it stands. What is key is the trip in, because diesel both ignites and — before that — protects the pump and the injectors, while petrol only ever ignites. Those couple of miles ran your pump on a fuel drained of a lot of its protection, and no volume of sitting in a car park gives any of that back. Hence the thing we ask about miles instead of hours standing, and hence the instruction to leave your keys be till our technicians arrive.
A passer-by will advise you to move the vehicle out of that gateway and sort it out later. Don't. A wrongly fuelled diesel Mercedes C-Class on the zig-zags outside St Maxentius CofE Primary School is a nuisance; the same car started three more times to be polite is a fuel system instead of a tank. Every restart primes the lines and pulls more petrol through your filter and into the pump. Stay put, let them complain, and call us.
The components that should be getting oiled are grinding instead, and the vehicle gives no sign of it: a diesel on a thinned tank fires up and drives off perfectly well. Chance the drive home from Grey Mare Inn? Not a chance. Phone and leave the Dacia Duster where it is.
Pulled off the forecourt, read the till receipt, and parked your diesel Ford Kuga up near Longsight Methodist Church Hall a few hundred yards later? That's about as well as this goes once your engine has turned. Phone us then leave it off. The short distance genuinely assists, but it was still a start and a drive, so thinned fuel has arrived at the fuel filter and your pump — which is why we purge the fuel lines rather than only clearing your tank.
The fuel filter, your lines, the pump and its rail: that is where the blend is once a diesel has run, and it does not come back out with your tank contents. So that tank isn't where most of the damage waits by this point, and a diesel Peugeot 208 that made it near St Brendans RC Church needs your circuit flushed instead of drained.
Draining petrol from a diesel on the forecourt
A big share of this work is done at a forecourt, because that is where it mostly kicks off. We work on garage forecourts regularly, with the owner's consent, and so if you're still at Morrisons that's typically where this drain gets done.
Nowhere but a forecourt can the mistake be caught with the motor still untouched. Anywhere else — a car park, a driveway, a lay-by — your car was started and driven to get there, which means fuel was pulled from your tank, through the filter and into the high-pressure pump. That's not a calamity, and we can still put it right where it stands. It does mean the lines and the fuel filter need cleaning as well as your tank, and that is decided by the few seconds between checking the till receipt and going for the key.
Staff will usually pitch in pushing it out from the petrol pump, which lets the next motorist get through. Accept the help. Moving it four lengths doesn't warrant firing the motor.
Coverage near Side of the Moor
These same rounds take us to Harwood Lee, Bradshaw Chapel, Bradshaw, Affetside and Bottom o th Moor as well as Side of the Moor, which is a residential suburb.
If yours isn't on this list it does not mean we never come — there are pages for nearly all towns across Greater Manchester, and the ones named above are merely the closest neighbours. Close to a border, or anywhere a satnav struggles with? Ring us to check rather than guessing.
This map shows the patch the page includes. The lot is territory our technicians serve: a roadside, a forecourt, a driveway, a car park. You don't drive your car anywhere.
Stranded by the kerbside somewhere in Side of the Moor?
A chance to stop somewhere suitable does not come to everybody. Set off, then noticed? Finished up by the verge on Seaford Road, or parked in some lay-by with your hazards going? That is a routine call here. Not an unusual one.
Whether you stay beside your car or move clear of it turns on whether staying nearby looks safe. Every mile a diesel obliges you for on petrol draws the mixture further into the system — and oblige it frequently will, which is why your motor doesn't get restarted to limp somewhere better. We will bring the van to a difficult spot without any bother, and for your car that's much better than driving on.
Petrol in a diesel, and the vehicle has rolled
This is where the local M66 counts, under 5 miles from Side of the Moor. It will usually take you onto it, and some way along, before you spot a thing. Then it is some smoke, a rough idle and power ebbing away — not a neat stop. Misfuelled diesels seldom give you one of those.
Never start it to move it. Get off at the next sensible exit then switch off. Long run? Anything approaching the under 10 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the phone, because it changes what goes in the van.

The call-out around Side of the Moor, step by step
- Our engineers ask first, quote after. What went in? How much? Has your motor run? Those responses alter what the work actually is.
- Out comes the tainted mixture.
- We rinse your fuel lines and clean the filter, and so what's left in your system is not what started the trouble.
- Your system gets bled, on clean diesel.
- We start the engine and confirm it runs properly on fresh diesel.
After that it's ready to drive away. Permanent damage is very rare when it has been caught early, and as everything is done where your car is, it never needs to go to a garage.
AdBlue in a diesel tank around Side of the Moor is a different problem
The problem isn't the same, though the opening step is — do not fire it up — if what got in was AdBlue rather than petrol. Petrol thins your diesel and removes the protection your fuel system depends on. AdBlue? Urea dissolved in water. Put that in with the diesel and you get rust instead, plus build-up.
Often the more significant of the two, AdBlue — and the detail lives on its own Side of the Moor page. Both are ours to deal with.
Side of the Moor costs for a petrol-in-diesel fuel drain
One figure wouldn't be fair here, because this isn't one job. These are the things that move it:
- Whether your engine has been started or driven. This is the big one.
- How much of the wrong fuel went in, set against how much that tank holds.
- The kind of liquid in the tank, petrol or AdBlue.
- Where your vehicle is, and if a van can safely reach and work on it.
Tell us what the vehicle is, how much went in, and if the engine has run. A clear answer comes back, not a range. For the car at home that's going nowhere and isn't time-critical, is fine too.
Side of the Moor drivers ask us these about petrol in diesel
Can you do a fuel drain at a petrol station in Side of the Moor?
Yes — forecourts are where a fair share of this takes place. Our engineers work at Shell and the other forecourts around town routinely, with the site's permission — tell us which one you're at when you call and we will tell you if our technicians can work there.
A few litres of petrol in a diesel — too much?
Litres aren't the measure. Proportion is, and far more than either, it matters if anything has been run. A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, definitely. Either way, the work required comes down to one thing, which is whether the fuel system has had that mixture drawn through it.
Already driven it with petrol in the diesel? Now what?
Stop somewhere safe, switch off, then leave the car off. Driving moves the issue along — out of your tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one genuinely useful thing left to you isn't restarting the car.
Will a fuel drain void my warranty?
A drain and flush carried out properly isn't a modification and doesn't void a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another good reason to leave the vehicle switched off.
Two-stroke oil in that tank, and then home?
What petrol has weakened is not replaced by two-stroke oil, which is an old fix for a different issue. So no. Your tank still has petrol in it later, and your pump still has to put up with it.
Does petrol in a diesel have to go to a main dealer?
There is no need to bring it to a franchised dealer, since we drain and flush the car wherever it is.
Waiting next to it?
Do not turn the car on again.
Turn it off somewhere safe and leave it off, if you have already driven it. Cold and stationary, a motor is in the best position available — and motorists fear this far more than the recovery rate warrants.
