Ash Vale: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Leave it that way — no moment on, no shifting it anywhere. Has not been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and no other factor settles that more than the next few minutes do. What follows is the sequence from here, anywhere around Ash Vale you are.
Motor off: minute one with petrol in a diesel
In this sequence, and before anything else:
- Priming the fuel system draws petrol from the tank towards the parts it harms, and turning your ignition on can be all it takes to do that. So your keys come out, and the ignition stays off altogether.
- Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture.
- Being seen comes before the rest near moving traffic: switch your hazards on, and only then think about anything else.
- However short the distance, starting it to move it is the mistake. At a forecourt, roll the vehicle away from the petrol pump by hand instead, and ask the attendants to help.
- Hold on to the receipt: the fuel and roughly how much are printed on it, and they're what we ask for first.
On the M3, under 5 miles from Ash Vale, the next exit is the place to come off; elsewhere, the first sensible place to stop. Do not push on to the services. Then go back to step one.
The fork in every Ash Vale fuel drain: has it run yet?
Everything after this stage rests on one answer.
If it has not once been started:
- The petrol sits in that tank, and only there.
- A drain and flush, on the spot, is normally the whole job.
- Step one counts for precisely this reason: it is the best place to be in.
If it has been started, even for a moment:
- From that tank, past the fuel filter, into the lines: that's how far that petrol has got.
- The high-pressure fuel pump as well as the fuel injectors see it too on a longer run.
- The farther it went, the bigger the job — the fuel lines, your filter, and sometimes more besides.
That line falls there because diesel protects the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't. In the tank, sitting still, petrol harms nothing. The parts that move it are wearing the moment petrol is being pumped.
What to have prepared when you call about petrol in a diesel from Ash Vale
Whether the technician circles or finds you depends on a little planning.
- GU12 5 and the remainder of the postcode makes the best way to start telling us where you are.
- Give the street — Vale Road or wherever you have pulled up — or the car park.
- Or the nearest landmark. A car park is easier to find by what it serves, like the one at Family Shopper.
- The make and model of your car, and the fact it is a diesel.
- Tell us which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Ash Vale.
- How much. Litres from your receipt, or how long the nozzle was in the filler.
- Whether it's run. Then if it has, how far plus how heavily.
- Hire or company car? Some contracts want the owner's go-ahead for the work, and getting it before our technicians turn up is quicker than afterwards.
Call 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use .
The wait for a Ash Vale fuel drain, and what to do in it
Hold to these: well-intended help causes the harm during the wait.
- Safety before your car. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it sits, stay with it.
- Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it.
- Anything from the boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.
- No home-made clearing. Siphoning petrol into a can at the roadside is dangerous, and it leaves the fuel that has already gone beyond the tank.
- Not for your radio, not for the windows: your ignition remains off.
Step by step: your fuel drain when the van arrives
- Three queries. What got in, how much, and if it has run. Those answers decide this job, which is why the price comes after them and not before.
- Clearing it is how the blend gets taken out of that tank.
- Cleaning your lines comes next, since a car that ran has petrol past the tank, in your lines themselves.
- Cleared, or replaced if your car has a serviceable one: your filter is dealt with next.
- Bleeding the system comes once clean diesel is in.
- Starting up. Once the fuel system is bled with fresh diesel, our technicians start the car and make sure it runs properly.
Your car has clean diesel running through it before our engineers go. If it has been spotted quickly, long-term damage is very rare, and the car returns to normal use straight away.
Once the fuel drain is done: driving in Ash Vale a second time
- Started on clean diesel, it needs nothing unusual of you. Simply drive normally.
- Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
- The work may matter later with a hire company, an insurer or a fleet manager. Keep the documents.
- Next time, read the petrol pump. The label, not the colour of its handle.
