What Happens Now: Petrol in a Diesel Car in Overstone
Stop. Engine off. Leave the car like that — no moment on, no shifting it at all. Drained then cleaned, just where it is: that is generally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes ahead more than on anything else. Wherever you happen to be in Overstone, here is the order things run from here.
Petrol in a diesel, motor off — the first minute
Do these before anything else, in this sequence.
- The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of your tank towards the components it damages.
- No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same mixture.
- Visibility comes first near moving traffic: switch your hazards on, and only then deal with everything else.
- Off the petrol pump by hand. At a forecourt, get the staff to help you roll it clear of the pump. Don't fire it up to shift it, however short the way.
- Which fuel, and about how much? Your receipt replies that, and that's where our questions start. Don't throw it away.
On the M1, under 10 miles from Overstone, the next exit is the location to come off; elsewhere, the first safe spot to stop. Do not press on to the services. Then go back to step one.
The fork in each Overstone fuel drain: has it run yet?
Everything after this point rests on one answer.
If it has not once been started:
- Nowhere but your tank: that's where that petrol yet is.
- Normally it is drained and cleaned just where your car stands.
- Being here is the best case — which is the entire point of stage one.
Motor run, even briefly?
- Out of that tank, past your filter, into your lines: that is how far the petrol has travelled.
- The high-pressure pump as well as the injectors see it too on a longer run.
- Flushing the lines, your filter dealt with, and sometimes more: this job grows as the distance does.
Why the line falls there: diesel protects the high-pressure fuel pump as well as the injectors as it passes through them, and petrol doesn't. Petrol sitting in a tank damages nothing. As soon as it is pumped, petrol begins wearing down whatever moves it.
What to have prepared when you call about petrol in a diesel from Overstone
Whether the van goes round or finds you depends on a little planning.
- Where you are. A postcode beginning NN6 0 is the ideal start.
- A road name helps: Sywell Road, say, or whatever street you have stopped in. A car park works too.
- Car parks are found more easily by what they serve: tell us the one at ALDI, and it is easy.
- The vehicle. Make, model, plus that it is a diesel.
- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has its own Overstone page.
- How much. Litres from the receipt, or how long the nozzle was in the filler.
- The mileage it did, and how heavily, if it ran at all.
- Hire or company car? Some agreements need the owner's go-ahead for this work, and sorting it before our engineers turn up is quicker than after.
Call 0333 366 0103 next. Writing to works as well if it can wait, with the car parked at home, going nowhere.
Overstone fuel drain on its way? While you wait
Help, however well meant, is the thing that does the damage while you wait. So hold to these.
- Stay with your car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it.
- Nobody — however kind — starts it, whether to see if it runs or to move your car a short way.
- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that takes the petrol back out.
- A DIY drain misses your fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous besides.
- Even your radio or your windows are not worth turning the ignition on for.
The fuel drain, step by step, once the van arrives
- Three questions. What got in, how much, and whether it has run. Those answers decide the job, which is why the quote comes after them and not before.
- Your tank is cleared. The polluted mix comes from the tank.
- If it ran, the lines are carrying petrol that has moved beyond your tank — so they're flushed.
- Cleared, or replaced if the car has a serviceable one: the fuel filter is dealt with next.
- Fresh diesel goes in, then your system is primed.
- Our engineers fire it up only after fresh diesel has gone in and primed your system, then confirm that it is running properly.
Only when it is running on fresh diesel do our engineers leave. It's very unusual for a car caught soon to be left with lasting damage, and normal use resumes straight away.
After the fuel drain is done: driving around Overstone a second time
- Nothing unusual is needed after a start with clean diesel — normal driving will do.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle stumbling: pull over then call us back.
- An insurer, a fleet manager or a hire firm may ask what was done, and so hold on to the documents.
- Next time, read the petrol pump. The label, not the colour of the handle.
