Marlow Bottom: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, never switch your engine on, even for a moment, to shift the car. Pause; leave it off. The coming few minutes determine it far more than anything else: petrol in a diesel still unrun generally comes down to clearing and cleaning, right there. Here's the sequence of things from here, wherever you're around Marlow Bottom.
Engine off: minute one with petrol in a diesel
Work through these in order, first.
- Bleeding the system pulls petrol from your tank toward the parts it damages, and switching the ignition on can be all it takes to do that. So the keys get taken out, and the ignition stays off completely.
- Topping up with diesel seems like it thins the issue. It does not: nothing comes out, and your tank simply holds more of the same.
- Get your car easy to see before anything else — hazard lights on — if there's moving traffic anywhere close to you.
- By hand, never under the motor: that's how it comes off the petrol pump. Get the forecourt attendants to help you push, whatever the mileage.
- Which fuel, and roughly how much? Your receipt replies both, and that's where our questions start. Don't throw it away.
Still on the move when you realised? Come off the M40 at the next exit if that's where you are, under 3 miles from Marlow Bottom, and pull over somewhere safe and not pressing on to the services. Then start at step one.
The fork in every Marlow Bottom fuel drain: has it run yet?
What happens after this turns on one answer, and just one.
Not run, not even briefly:
- All the petrol sits in your tank, and only there.
- The work is a simple drain and a flush, usually done where the vehicle stands.
- This is the best position to be in, and the whole reason step one counts.
Run at all, even for a second:
- Petrol has been drawn out of that tank, past the filter and into your lines.
- Your high-pressure pump and your injectors get it on a bigger run.
- Distance is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work.
The reason the line falls there: diesel protects the high-pressure pump as well as your injectors as it flows through them, and petrol doesn't. In your tank, left alone, petrol does no harm. Move that petrol, though, and it grinds down the very parts doing the moving.
Calling about petrol in a diesel from Marlow Bottom: what to have prepared
Get ready a little, and the van finds you rather than circling.
- SL7 3 plus the rest of the postcode makes the best way to begin telling us where you are.
- A road name helps: New Road, say, or whichever street you have stopped in. A car park does the trick too.
- What a car park serves is the quickest way to find it, so say the landmark — such as the one outside Lidl.
- That it is a diesel, along with the make and model of the car.
- Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Marlow Bottom page.
- How long the nozzle was in, or the litres from your receipt — whichever tells us how much.
- The mileage it did, and how hard, if it has run at all.
- The owner may have to authorise this work under some hire or company contracts — which is why it's faster to settle whose car it is before we arrive.
Call 0333 366 0103 then. Email works too if it can wait, with the vehicle left at home, going nowhere.
Waiting for a fuel drain in Marlow Bottom: what to do
Hold to these: well-intended help causes the harm during the wait.
- Where the car has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle.
- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.
- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time.
- Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank remains put anyway.
- Ignition stays off. Even for your radio or your windows.
Van arrived? Your fuel drain, one step at a time
- Our quote comes after three queries, not before them — what got in, how much, and if it's run — because those answers decide the job.
- That tank is cleared. The tainted mixture comes out of the tank.
- Purging the fuel lines comes next, because a vehicle that ran has petrol past the tank, inside the lines themselves.
- Then the filter: swapped where there is a serviceable one, cleared where there is not.
- Priming comes once fresh diesel is in.
- Our engineers fire it up only after new diesel has gone in and bled the fuel system, then confirm that it's running correctly.
We wait until it's running on clean diesel. Permanent damage is very uncommon when it has been noticed soon, so the car can go right back to normal use.
After the fuel drain is done: driving around Marlow Bottom again
- Started on clean diesel, it asks nothing unusual of you. Simply drive normally.
- Pull over and ring us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot.
- Keep the documents. A hire company, a fleet manager or an insurer may ask what was carried out.
- Next time, go by the pump's label instead of the colour of its handle.
