RAF Coltishall: Put Petrol in a Diesel Car?
With the tank still carrying the petrol and the motor not yet started, nearly every job needs only a drain, so leave the motor off. That result is settled in the minutes immediately after the fill-up, rather than by the amount that got in. Across RAF Coltishall and the rest of Norfolk, Petrol in Diesel drains the car and flushes it where it sits, whether at a roadside, on a private drive or at a forecourt. Just one ring our way will be sufficient: our technicians shall tell you what comes next. Make that first.
Petrol in a diesel: what to try now
- Give a petrol motor diesel and it will usually fail to run at all, and so the driver stops there and so does the harm. Feed a diesel petrol and the engine starts, it ticks over, it moves off — all right for a couple of miles. People have that reversed, which is the thing they get wrong about petrol in a diesel specifically. So do not start the vehicle. And once started, never trust it: that fuel system is wearing down while you drive.
- Two tasks, diesel: it combusts, and on the way through it keeps that high-pressure pump and injectors oiled. Petrol only does the one. Which is why the car's ignition remains off also — flick it on and you commonly prime that system, and that is petrol exiting your tank for just those parts.
- That guidance assumes a diesel fuel system copes with petrol by percentage. It does not. Put diesel on top and nothing at all is removed; what you get is a fuller tank of the same mix. And no, the octane makes no difference — super unleaded is just petrol.
- Wait where you are if you reasonably can. A motor that has never moved is the simplest one to sort out, and we would sooner get to an odd place than have it started. If you are parked on the verge on Church Road, put your hazards on then leave the car there.
- Before you dial, get your location. Anything closest to you with a sign on it, plus a postcode beginning NR10 5 — that's what decides whether the van turns up or circles.
- What went in, roughly how much, plus if the engine has fired — the three replies settle the whole job. Ring 0333 366 0103 then tell us.
Nothing about the time since has lost you anything. Fuel in a tank is idle, and so a diesel Volkswagen Passat sitting at Worstead this morning is no worse at five than it was at nine — what pushed thinned diesel through the pump was the trip in. Phone us before you go to collect the car.
Simple, these ones, and the reason is the mileage: a mile at easy throttle draws hardly any diesel. Petrol into a diesel Renault Clio somewhere in RAF Coltishall, a boot loaded with shopping, and you stuck outside Roys — ring us. Getting out of that bay isn't worth a restart. Your tank gets cleared where it stands, the fuel lines rinsed, clean diesel in, and you head home.
Move it out of the gateway and sort it out later — that is what someone will say, and it's wrong. Parked on the zig-zags outside Swanton Abbott Community Primary School, a wrongly fuelled diesel Audi A4 is a nuisance and nothing worse. Started three more times for courtesy, it is no longer a tank problem but a fuel system one, as priming happens with every start and more petrol goes past the filter towards your pump. Let people complain. Give us a call.
You set off at the end, once our engineers have fired it up and confirmed it runs smoothly on fresh diesel, with the fuel system bled. Before that, in the car park outside The Diplomat, the polluted fuel comes out of the tank, the fuel lines get flushed and the filter comes off where your Ford Focus has a replaceable one. It all begins with three questions when our engineers get to your car: what went in, how much of it, and whether it has been fired up since.
Your filter, your lines, your pump and its rail: that's where the mixture is once a diesel has run, and it doesn't come back out with your tank contents. So that tank is not where most of the trouble rests by this point, and a diesel Vauxhall Astra that got by Saint Edward's Church needs the circuit flushed instead of cleared.
At a forecourt: removing petrol from your diesel
It kicks off at the pump, usually. Quite often the job ends on site too. Still at Esso? Then that's typically where it takes place. Garage forecourts are normal for us, with the agreement of the owner.
No place except a forecourt can it be halted with the engine still unrun. Anywhere else — a car park, a drive, a lay-by — the vehicle was started and moved to get there, which means fuel was drawn from your tank, through the fuel filter then into the high-pressure pump. That is not a calamity, and our engineers can still put it right where it sits. It does mean the fuel lines and your filter need rinsing as well as the tank, and that is decided by the few seconds between seeing the receipt and reaching for the key.
The staff will usually offer to push the car clear of the petrol pump so the next motorist can get past. That's worth doing. Cranking the car just to shift four vehicle lengths isn't.
Areas our vans cover around RAF Coltishall
The same runs take us to Badersfield, Scottow, Lamas, Little Hautbois and Swanton Abbott besides RAF Coltishall, which is a small village.
There are separate pages for nearly all towns in Norfolk, and the ones listed above are simply the immediate neighbours — so yours being left off the list tells you nothing whatsoever about if we come. Phone and check instead of presuming — county lines particularly, and wherever your phone may get wrong.
This map shows the area this page includes. Every bit of that is territory our engineers work: a roadside, a forecourt, a drive, a car park. You never drive the car anywhere.
Kerbside stops in RAF Coltishall
Not everyone gets the opportunity to pull in somewhere suitable. Hazards flashing at a lay-by somewhere, or pulled onto the verge beside Lamas Lane because you noticed after setting off — we take that call regularly enough that it's the usual kind.
Whether you wait with the vehicle or step clear of it turns on if sitting nearby seems wise. Do not restart your engine to nurse the car somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the blend further into your fuel system. Our van driving to a difficult location is no problem for us, and it's much better for the car than carrying on.
So you've run it? Petrol in a diesel over some miles
Here is where your M11 matters, over 50 miles out of RAF Coltishall. It will usually get you onto it, and some way along, before you notice a thing. Then it is some smoke, an uneven idle and power draining away — not a tidy stop. Wrongly fuelled diesels rarely give you one of those.
Take the first junction that's safe, pull up there, and don't restart the vehicle to reposition. Assume the worst of it on a long drive. Anything approaching the under 10 miles to the nearest city, and the petrol has been through your filter, through your pump, through your injectors. Say so when you ring. What we bring differs.

Our call-out around RAF Coltishall, step by step
- Three things get asked before any price — your fuel that was put in, the amount, and if anything has been run since. Each answer changes the work.
- Away goes the contaminated mixture.
- Fuel lines are cleaned through and the fuel filter cleaned, leaving nothing in your system that caused any of this.
- Bleeding your system follows, once new diesel is in.
- After it's fired up, our technicians check it runs smoothly on fresh diesel.
That has the car ready to set off. Lasting damage is very rare when it has been noticed quickly, and because everything is done where your car is, it never needs to go to a garage.
AdBlue in a diesel tank in RAF Coltishall is a separate job
The issue is not the same, though the opening step is — do not crank it — if what was put in was AdBlue rather than petrol. Petrol dilutes your diesel and takes away the protection the system depends on. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and build-up instead.
Usually the more significant of the two, AdBlue — and the detail sits on its own RAF Coltishall page. Both are ours to deal with.
What a petrol-in-diesel drain will cost around RAF Coltishall
Our engineers cannot put one price on this page honestly, as the job isn't one job. What changes it:
- This is the key one: whether your engine has been run, or driven.
- Wrong fuel in, against what that tank takes — that ratio.
- Which got in: unleaded or AdBlue.
- Whether a technician can safely get to the vehicle and work on it, which rests on where your car is.
Tell us the car, the quantity and whether it has run, and you will get a firm answer instead of a range. For the car at home that is going nowhere and is not urgent, is fine too.
Petrol in diesel queries from RAF Coltishall drivers
At a petrol station around RAF Coltishall, can you do a fuel drain there?
A large share of this work takes place there, so yes. Permission from the site is the condition. Given that, a forecourt like BP is somewhere we are frequently, along with the rest of them locally — so name yours on the phone and you will hear whether working there's possible.
A couple of litres of petrol in a diesel — too much?
Proportion decides it instead of litres — and more than either, whether the engine has run. What decides how much work is required is whether that blend has been pulled through your fuel system — because though five litres in an almost empty tank is a different matter from five in a full one, either way that's the question.
Already driven it with petrol in the diesel? What then?
Stop safely. Off. Nothing after that. It's recoverable a lot more frequently than people fear, even though driving is what takes the issue from the tank into your pump and injectors — and the single most useful thing you can do now is not restart it.
My warranty — does a fuel drain void it?
A drain and flush carried out correctly isn't a change and does not void a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one.
Could I put some two-stroke in and just drive?
No. Two-stroke oil is an old remedy for a different fault and it does not replace what petrol has thinned. Petrol remains in that tank afterwards, whatever else goes in, and the pump gets no reprieve from it.
A main dealer for petrol in a diesel — necessary?
Wherever the vehicle is, our engineers drain and flush it there, so a visit to the main dealer doesn't come into it.
Standing next to it?
Your engine stays off.
If you have already driven the car, pull in somewhere safe, turn it off and keep it off. A parked, cold motor is the best place to be in, and this is recoverable from much more commonly than drivers assume.
