Dooish: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch your engine on, even briefly, to move it. Stop; leave the vehicle off. Emptied and rinsed, right where it is: that's usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes ahead more than on everything else. Here is the order of things from here, wherever you're around Dooish.
Minute one: petrol in a diesel, engine off
Work through these first, in this sequence.
- Bleeding the system draws petrol from your tank towards the components it damages, and switching your ignition on can be enough to do that. So your keys get taken out, and your ignition remains off completely.
- Don't top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mixture.
- Hazard lights on. If you are anywhere close to moving traffic, make the car easy to see before you do anything else.
- Off the pump by hand. At a forecourt, ask the staff to help you roll it clear of the petrol pump. Don't start it to move it, however short the distance.
- Which fuel, and roughly how much? The receipt replies both, and that is where our first question starts. Don't bin it.
On the M77, over 50 miles from Dooish, the next exit is the spot to come off; anywhere, the first sensible location to stop. Don't push on to the services. Then go back to stage one.
Dooish fuel drain: has the engine run yet, or not?
Everything after this point depends on one answer.
Engine not run at all?
- Only the tank has petrol in it so far.
- The job is a drain and a flush, normally done where your car stands.
- Being here is the best case — which is the entire point of step one.
If it's been started, even for a second:
- The fuel lines and the fuel filter now hold petrol drawn out of the tank.
- Run it further and the petrol gets to the injectors, having passed through your fuel pump first.
- The job expands with the mileage — lines rinsed, filter dealt with, occasionally more.
The line falls there since diesel protects the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, hurts nothing. Move that petrol, though, and it grinds down the very parts that move it.
Dooish, petrol in a diesel: have these ready before you call
A little preparation is the difference between a technician that finds you and a van that circles.
- BT78 4 plus the remainder of the postcode is the ideal way to start telling us where you are.
- The road or the car park. A road name is a help — Rock Street, or wherever you have pulled up.
- Or the landmark. A car park is quicker to find by what it serves, such as the one outside the local shops.
- The car. Make, model, and that it's a diesel.
- Say which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Dooish.
- Roughly how much — in litres from your receipt, or by how long the nozzle was in.
- Whether it's run. And if it has, how far and how hard.
- The owner may have to authorise this work under some hire and company contracts — which is why it is quicker to settle whose motor it is before we arrive.
Call 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use .
While you wait for a fuel drain around Dooish
During the wait, the harm comes from well-meant help — so these matter.
- Stay with your car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards.
- Anything from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol.
- No home-made draining. Siphoning petrol into a can by the kerbside is hazardous, and it leaves the fuel that has by now gone beyond the tank.
- Ignition stays off. Even for the radio or your windows.
When our van arrives: the fuel drain, step by step
- Three questions. What went in, how much, and whether it's run. Those replies set the job, which is why our quote comes after them but not before.
- Out of that tank comes the polluted blend: your tank is drained.
- Flushing your lines comes next, because a vehicle that ran has petrol past the tank, in the fuel lines themselves.
- Where the car has a usable filter, it's swapped; otherwise, cleared.
- Bleeding your system follows after fresh diesel is in.
- The start. With fresh diesel in and the fuel system primed, it is fired up and checked to confirm it runs properly.
We remain until it's running on fresh diesel. When it has been caught soon, lasting damage is very uncommon, and the car returns to normal driving at once.
Back on the road around Dooish after the fuel drain
- Nothing special is needed after a start with fresh diesel — ordinary driving is all.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and call us once more.
- An insurer, a fleet manager or a hire firm may ask what was done, and so keep the documents.
- Next time, check the pump. The label, not the colour of the handle.
