Boundstone: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Leave the car like that — no second on, no shifting it anywhere. The coming few minutes settle it more than anything else: petrol in a diesel still unrun normally comes down to draining then cleaning, on the spot. Anywhere you are in Boundstone, this is how things go from here.
Minute one: petrol in a diesel, engine off
First, the following — following this sequence.
- Ignition off, keys out. Switched on, your ignition can prime your system — and priming is what draws petrol out of the tank into the parts it damages.
- Topping up with diesel sounds like it dilutes the trouble. It does not: nothing comes out, and your tank just holds more of the same.
- Hazard lights on. If you are at all near moving traffic, make the vehicle simple to see before you do anything else.
- Off the petrol pump by hand. At a forecourt, get the attendants to help you roll the vehicle clear of the petrol pump. Do not fire it up to shift it, however short the distance.
- The first question we will ask is which fuel you put in and roughly how much — and the receipt says both. Keep it.
If you were still driving when you realised, stop somewhere safe rather than pushing on for the services — on the M3, under 10 miles from Boundstone, that means the next junction. Step one comes next.
Every Boundstone fuel drain starts here: has the motor run?
From this point on, everything comes down to a single answer.
Not run, not even once:
- The petrol is still in the tank and nowhere else.
- Draining and flushing, on the spot, is usually the whole job.
- No place is better, and it's why the first step matters so much.
If it's been started, even for a moment:
- Some petrol has left that tank by now, gone through the fuel filter, and reached the lines.
- The high-pressure fuel pump as well as your injectors see it too on a bigger run.
- Flushing the lines, the fuel filter seen to, and sometimes more: this job grows as the miles does.
The line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol doesn't. In that tank, sitting still, petrol harms nothing. The components that shift it are wearing the moment petrol is being pumped.
Boundstone, petrol in a diesel: have these ready before you call
Get ready a little, and the van finds you instead of circling.
- Your whereabouts: a postcode beginning GU10 4 serves best.
- Give the street — Sandrock Hill Road or wherever you have pulled up — or the car park.
- Describe a car park by what it serves — the one outside Co-op Food, for example — and it is far quicker to find.
- The make and model of the vehicle, and the fact it's a diesel.
- Which got in matters: AdBlue is a separate job from petrol, plus Boundstone has a page for it. So tell us.
- The quantity: your receipt's litres, or otherwise how long you had the nozzle in.
- Has it run? If so, tell us how far it got, and how it was driven.
- Whose vehicle it is. Some hire or company agreements want the owner to authorise this work, and that is quicker settled before our technicians get there than after.
Ring 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use .
Waiting for a fuel drain in Boundstone: what to do
Help, however well meant, is what does the damage while you wait. So hold to these.
- Where the vehicle has stopped settles where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the car.
- Nobody — however helpful — starts it, whether to see if it runs or to move the car a short way.
- Anything from your boot, oil made for two-strokes or injector cleaner: no additive removes that petrol.
- No DIY draining. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has by now gone beyond your tank.
- Ignition stays off. Even for the radio or the windows.
Van arrived? Your fuel drain, one step at a time
- Fuel, quantity, whether it has run: the answers decide the job, and that is why we give a quote after them instead of before.
- Clearing it's how that mixture gets taken from your tank.
- Petrol that has shifted beyond your tank sits in the fuel lines once it ran, and your lines are purged to shift it.
- Then the filter: changed where there is a serviceable one, cleared where there is not.
- Fresh diesel goes in, then your system is primed.
- Starting the car. After the system is primed with fresh diesel, our technicians start the engine and check it runs correctly.
Only once it is running on new diesel do we go. Permanent damage is very uncommon if it has been noticed quickly, so your car can go right back to normal use.
After your fuel drain: back on the road in Boundstone
- Drive normally. There's nothing special to do once it has been started on fresh fuel.
- Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot.
- An insurer, a fleet manager or a hire firm may ask what was done, and so keep the documents.
- Check the label on the petrol pump next time, not the colour of its handle.
