Stanmer: Petrol in a Diesel Car? Here Is What Happens
Pause, and leave the motor off — not on, and not for a second to shift it. Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the vehicle has stopped — and no other factor settles that more than these next few minutes do. What follows is the sequence from this point, anywhere around Stanmer you happen to be.
Petrol in a diesel, motor off — the first minute
Do these before anything else, in this sequence.
- The keys out of the ignition. Turning your ignition on can be all it takes to prime the fuel system, and priming draws petrol out of the tank toward the parts it damages. Leave the vehicle off completely.
- Do not top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mixture.
- Close to passing traffic? Then the hazard lights go on before everything else, so your car is easy to see.
- By hand, not on your engine: that is how it comes off the pump. Ask the forecourt staff to help you roll, however short the mileage.
- Keep the receipt. It says which fuel got in plus about how much, which is the first thing we will ask.
If you were still driving when you realised, pull over somewhere sensible instead of pushing on for the services — on the M23, under 25 miles from Stanmer, that means the next exit. Stage one follows.
The fork in every Stanmer fuel drain: has it run yet?
Everything after this point depends on one answer.
If it has not once been started:
- Nowhere but that tank: that is where that petrol yet is.
- The job is a drain and a flush, normally done where your car stands.
- Step one counts for exactly this reason: it is the best place to be in.
Motor run, even briefly?
- Some petrol has left the tank by now, passed through your filter, and got into the fuel lines.
- Run it further and that petrol gets to your injectors, having passed through your fuel pump first.
- Lines flushed, the fuel filter sorted, occasionally more: this job grows as the mileage does.
That line falls there because diesel lubricates the high-pressure pump and your injectors on its way through them — and petrol does not. Petrol sitting in a tank damages nothing. Move the petrol, though, and it grinds down the very parts doing the moving.
Stanmer, petrol in a diesel: have these ready before you call
Prepare a little, and the van finds you rather than circling.
- BN1 9 plus the rest of the postcode makes the best way to begin telling us where you are.
- A road name is a help: A27, say, or whatever street you've stopped in. A car park works too.
- Name a car park by what it serves — the one at Taj, for instance — and it is much easier to find.
- The car. Make, model, and that it's a diesel.
- Tell us which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Stanmer.
- About how much — in litres from your receipt, or by how long the nozzle was in.
- The mileage it did, and how heavily, if it ran at all.
- Sort who has your car ahead of when we arrive: some hire and company agreements want the owner to authorise the work, and doing it faster beforehand.
Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too.
Whilst you wait for a fuel drain around Stanmer
The wait is where well-meant help does the harm. Hold to these.
- Stay with the 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.
- None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives.
- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains put regardless.
- Ignition remains off. Even for your radio or the windows.
Van arrived? The fuel drain, one step at a time
- Our quote comes after three queries, not before them — what was put in, how much, and if it has run — because those answers shape this job.
- Then the tank is drained, and the contaminated fuel comes out.
- Cleaning the lines follows, since a vehicle that ran has petrol past the tank, in the lines themselves.
- The filter is dealt with. Cleared, or swapped where your car has a usable one.
- Fresh diesel goes in, and your system is primed.
- The start-up. With clean diesel in and your system primed, it's fired up and tested to make sure it runs properly.
Only once it is running on clean diesel do we head off. If it has been spotted quickly, lasting damage is very rare, and your car goes back to normal driving right away.
Back on the road in Stanmer after the fuel drain
- Nothing special is needed after a start with fresh diesel — normal driving will do.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and ring us again.
- Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out.
- Next time, check the petrol pump. The label, not the colour of the handle.
