Renishaw: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Leave it that way — no second on, no moving it at all. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and nothing decides that as much as these next few minutes do. From now on, step by step, for anywhere around Renishaw:
Petrol in a diesel, motor off — the first minute
Work through these before anything else, in this order.
- Keys out of your ignition. Turning the ignition on can be enough to prime the fuel system, while priming pulls petrol out of your tank towards the components it damages. Leave it off altogether.
- A bigger tank of the same mixture is all topping up leaves you, since it takes out nothing. So no more diesel.
- Being seen comes before the rest beside moving traffic: switch the hazards on, and only then think about anything else.
- By hand, never on your engine: that is how it comes off the petrol pump. Ask the forecourt attendants to help you push, whatever the mileage.
- The first thing you will be asked is which fuel you put in and roughly how much — and the till receipt shows both. Keep it.
On the M1, under 3 miles from Renishaw, the next exit is the location to come off; anywhere, the first sensible location to stop. Do not push on to the services. Then go back to step one.
The fork in each Renishaw fuel drain: has it run yet?
What happens next rests on one answer, and only one.
Engine not run at all?
- Nowhere but your tank: that is where that petrol still is.
- Draining and flushing, on the spot, is usually all of it.
- No position is better, and it's why the first stage counts so much.
If the motor has been run, even for a moment:
- From the tank, through your filter, into the fuel lines: that is how far that petrol has got.
- Your high-pressure pump and your injectors get it on a bigger run.
- The job grows with the miles — lines purged, filter seen to, occasionally more.
The line falls there because diesel protects your high-pressure pump and your injectors on its way through them — and petrol doesn't. Petrol resting in a tank harms nothing. Move that petrol, though, and it grinds down the very parts that move it.
What to have prepared when you call about petrol in a diesel from Renishaw
A little preparation is the difference between a technician that finds you and a technician that goes round.
- Where you have stopped. A postcode beginning S21 3 is the ideal start.
- Give the street — Main Road or wherever you have stopped — or the car park.
- What a car park serves is the easiest way to find it, so say the landmark — like the one outside The Co-operative Food.
- The make and model of the car, and the fact it is a diesel.
- Tell us which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Renishaw.
- The amount: your receipt's litres, or else how long you held the nozzle in.
- The mileage it did, and how hard, if it ran at all.
- Hire or company car? Some agreements need the owner's go-ahead for the work, and getting it before our engineers get there is quicker than afterwards.
Ring 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use .
Renishaw fuel drain on its way? Whilst you wait
The wait is where kindly meant help does the damage. Stick to these.
- Where the vehicle has stopped settles where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car.
- A helpful passer-by does not start it. Nor does anyone checking it still does the trick, or moving it a few yards.
- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that takes the petrol back out.
- Siphoning petrol into a can by the roadside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain.
- Not for your radio, not for the windows: your ignition remains off.
Step by step: the fuel drain when our van arrives
- Three questions. What went in, how much, and if it's run. Those replies set the job, which is why our quote comes after them and not before.
- Out of that tank comes the contaminated mixture: that tank is emptied.
- Petrol that has moved beyond your tank travels in the lines once it ran, and the lines are cleaned to clear it.
- Cleared, or changed if the vehicle has a workable one: your filter is sorted next.
- Clean diesel goes in, then the fuel system is primed.
- First start on clean diesel. When bleeding is done, the motor is fired up and our technicians confirm that it runs correctly.
Until it runs on fresh diesel, we stay with it. It is very rare for a car noticed soon to be left with long-term damage, and normal use starts again right away.
After the fuel drain: back on the road in Renishaw
- Started on fresh diesel, it asks nothing special of you. Just drive normally.
- Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over then call us back.
- Your documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Next time, go by the petrol pump's label instead of the colour of its handle.
