What Happens Now: Petrol in a Diesel Car in Oval
Whatever you do, don't switch your motor on, even briefly, to shift the car. Pause; leave the car off. Petrol in a diesel that hasn't been run is normally a drain plus a flush, done right where your vehicle stands, and what you do in the coming few minutes decides that more than anything else. Wherever you happen to be in Oval, this is the order things go from here.
Minute one: petrol in a diesel, engine off
Work through these before anything else, in this sequence.
- Keys out of your ignition. Turning the ignition on can be all it takes to prime the fuel system, and priming pulls petrol out of your tank toward the parts it damages. Keep the vehicle off altogether.
- A fuller tank of the same mix is all adding diesel leaves you, because it removes nothing. So no more diesel.
- Make the car simple to see first — hazards on — if there's moving traffic anywhere near you.
- However short the distance, starting it to shift it is the thing to avoid. On a forecourt, roll the car clear of the petrol pump by hand instead, and ask the staff to help.
- Keep your receipt. It says which fuel was put in and about how much, which is the first thing we will ask.
Realised on the move? Get off at the next exit if you are on the M4, under 10 miles from Oval, and stop somewhere safe — not at the services farther on. Stage one comes after that.
Has it run yet? The fork in each Oval fuel drain
What happens after this rests on one answer, and just one.
Motor not run at all?
- The petrol sits inside that tank, and only there.
- Usually it's drained and flushed right where your car is.
- No place is better, and it's why the first step matters so much.
If your motor has been run, even for a moment:
- Some petrol has left that tank already, gone through the filter, and reached the lines.
- The high-pressure fuel pump as well as your injectors get it on a longer run.
- Mileage is what makes it a bigger job: the lines flushed, a filter seen to, and at times more than that.
Diesel keeps the high-pressure pump and the injectors protected as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. Petrol sitting in a tank harms nothing. Pump the petrol, though, and it wears the very parts doing the moving.
Calling about petrol in a diesel from Oval: what to have ready
Whether the van goes round or finds you depends on a little planning.
- Where you are. A postcode beginning SW8 1 is the ideal place to start.
- Wherever you have pulled up, the road's name helps — whether that is Fentiman Road or somewhere else — and so does the name of a car park.
- Car parks are found most easily by what they serve: tell us the one outside Sainsbury's, and it's straightforward.
- Tell us what your car is — make, model — and check it's diesel.
- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Oval page.
- How long the nozzle was in, or the litres on your receipt — either gives us how much.
- If it's run, how far and how heavily — and if it has run at all.
- Settle who has your car ahead of when our technicians get there: some hire and company contracts want the owner to approve the work, and doing it faster first.
Phone 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use .
Waiting for a fuel drain around Oval: what to do
The wait is where well-intended help does the harm. Hold to these.
- Wait with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- Nobody — however helpful — starts it, whether to see if it runs or to move your car a short way.
- None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
- Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain.
- Not for the radio, not for the windows: the ignition stays off.
Step by step: the fuel drain when our van arrives
- Fuel, amount, whether it's run: the answers decide the job, and that is why we give a price after them rather than before.
- Your tank is cleared. The polluted mixture comes out of the tank.
- Petrol that has shifted beyond that tank travels in the lines if it ran, and your lines are cleaned to shift it.
- Cleared, or changed if your car has a workable one: the filter is sorted next.
- Bleeding your system comes once fresh diesel is in.
- Our engineers start it only after clean diesel has gone in and primed your system, then confirm that it is running correctly.
Only when it's running on fresh diesel do we head off. The vehicle returns to normal driving right away, and lasting damage is very uncommon when it has been noticed soon.
Oval, after your fuel drain: back on the road
- Started on fresh diesel, it asks nothing unusual of you. Simply drive normally.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over then call us back.
- Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was carried out.
- Next time, read the petrol pump. The label, not the colour of its handle.
