Coley: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not for moving it: your engine stays off. Stop there. The coming few minutes settle it far more than anything else: petrol in a diesel still unrun generally amounts to draining and purging, on the spot. From now on, step by step, for anywhere around Coley:
Petrol in a diesel? What to do in minute one
Work through these before anything else, in this sequence.
- Pull the keys out. Even the ignition on its own can prime your fuel system, drawing petrol out of the tank to precisely the components it harms, and so leave it off completely.
- Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mix.
- Close to moving traffic? Then the hazards come on before anything else, and so the car is easy to spot.
- Off the pump by hand. On a forecourt, ask the attendants to help you push it away from the petrol pump. Don't crank it to move it, however short the way.
- Hold on to the till receipt. It says which fuel got in and about how much, which is the first thing we will ask.
Realised on the move? Get off at the next junction if you are on the M4, under 3 miles from Coley, and stop somewhere safe — not at the services further on. Step one starts after that.
Has it run yet? The fork in each Coley fuel drain
What happens after this rests on one answer, and just one.
Engine never run at all?
- Only the tank has petrol in it so far.
- Normally it is drained and flushed just where your car is.
- This is the best case — which is the whole point of stage one.
If it's been started, even for a second:
- From the tank, through the filter, into the lines: that is how far that petrol has got.
- A longer run carries it all the way to the high-pressure fuel pump and the injectors.
- Flushing your lines, the fuel filter sorted, and sometimes more: the job expands as the mileage does.
The line falls there because diesel protects the high-pressure fuel pump and the injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, hurts nothing. Petrol being pumped is wearing the components that shift the car.
Before you call about petrol in a diesel around Coley: what our engineers need
Get ready a little, and the technician finds you rather than circling.
- Where you have stopped. A postcode beginning RG1 6 is the ideal place to start.
- A road name helps: Garnet Street, say, or whichever street you've stopped in. A car park does the trick too.
- What a car park serves is the quickest way to find it, so mention the landmark — like the one at The Food Warehouse.
- Tell us what the car is — make, model — and confirm it's diesel.
- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Coley page.
- How much. Litres from the receipt, or how long the nozzle was in the filler.
- Has it run? If so, say how far it went, and the way it was driven.
- The owner may have to authorise this work under some hire or company agreements — which is why it's quicker to settle whose car it is before our technicians arrive.
Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works as well.
The wait for a Coley fuel drain, and what to do in it
Help, however well meant, is the thing that does the harm whilst you wait. So stick to these.
- Wait with the vehicle if it is safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it.
- Nobody — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way.
- None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives.
- No home-made clearing. Siphoning petrol into a can at the roadside is hazardous, and it leaves the fuel that has already gone beyond the tank.
- Not for your radio, not for the windows: your ignition remains off.
The fuel drain, step by step, after our van arrives
- First, three questions: which fuel got in, the quantity, and has it run? Those replies decide this job, and so the price follows them.
- Out of the tank comes the polluted blend: that tank is drained.
- Petrol that has shifted beyond your tank travels in the lines once it ran, and the lines are cleaned to shift it.
- Where the vehicle has a usable filter, it is changed; otherwise, cleared.
- Bleeding the system comes once fresh diesel is in.
- Starting the car. Once the fuel system is primed with fresh diesel, our engineers fire it up and check it runs smoothly.
Only when it is running on fresh diesel do our engineers head off. Long-term damage is very uncommon if it has been spotted soon, so the car can go right back to normal driving.
Back on the road around Coley after your fuel drain
- Nothing special is needed after a start with clean diesel — normal driving will do.
- Pull over and call us back if anything looks wrong early on — a light on the dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot.
- The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to the documents.
- Check the label on the pump next time, not the colour of its handle.
