Thistleboon: Petrol in a Diesel Car? Here Is What Happens
Pause, and leave the motor off — not on, and not for a moment to shift the car. The next few minutes decide it more than anything else: petrol in a diesel still unrun usually comes down to clearing then rinsing, on the spot. Here is the sequence of things from here, anywhere you are around Thistleboon.
Minute one: petrol in a diesel, engine off
Work through these in sequence, before you do anything else.
- Pull your keys out. Even your ignition by itself can prime the fuel system, drawing petrol out of the tank to exactly the components it harms, and so leave the car off wholly.
- No diesel on top. More fuel in takes away none of the petrol — it just makes you with more of the same blend.
- Near passing traffic? Then the hazard lights come on before anything else, so your car is simple to see.
- However short the distance, starting it to shift it is the mistake. At a forecourt, push the car away from the petrol pump by hand instead, and ask the attendants to help.
- The first question we will ask is which fuel you put in and roughly how much — and your receipt says both. Keep it.
If you were still on the move when you noticed, stop somewhere safe rather than pushing on for the services — on the M4, under 10 miles from Thistleboon, that means the next exit. Stage one comes next.
Has it run yet? The fork in each Thistleboon fuel drain
From this stage on, everything comes down to a single answer.
Motor never run at all?
- The petrol is still in that tank and nowhere else.
- Usually it is drained and cleaned just where the car stands.
- No place is better, and it is why the first step counts so much.
Run at all, however briefly:
- Some petrol has left that tank already, passed through the fuel filter, and got into the fuel lines.
- The high-pressure fuel pump as well as the fuel injectors see it too on a longer run.
- The farther it went, the larger the job — the fuel lines, the fuel filter, and now and then more besides.
Diesel keeps the high-pressure pump and the fuel injectors lubricated as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. In that tank, left alone, petrol harms nothing. Move the petrol, though, and it wears the very parts doing the moving.
Before you call about petrol in a diesel around Thistleboon: what our technicians need
Whether the technician circles or finds you depends on a little preparation.
- Your location: a postcode beginning SA3 4 serves best.
- A road name is a help: Thistleboon Drive, say, or whatever street you've stopped in. A car park works too.
- Or the nearest landmark. A car park is easier to find by what it serves, such as the one outside M&S Food.
- The make and model of your vehicle, and the fact it's a diesel.
- Tell us which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Thistleboon.
- About how much — in litres from your receipt, or by how long the nozzle was in.
- Has it run? If so, tell us how far it went, and how it was driven.
- Whose motor it is. Some hire or company contracts want the owner to authorise the work, and that's quicker settled before our technicians arrive than after.
Ring 0333 366 0103 then. Writing to works as well if it can wait, with the car parked at home, going nowhere.
Whilst you wait for a fuel drain in Thistleboon
Stick to these: well-intended help does the harm during the wait.
- Wait with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- A helpful passer-by does not fire it up. Nor does anybody wanting to check it still works, or rolling it a couple of yards.
- Something from the boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol.
- Siphoning petrol into a can at the roadside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't drain the car yourself.
- The ignition remains off. Even for your radio or the windows.
Van arrived? The fuel drain, one step at a time
- Fuel, quantity, whether it has run: the answers decide the job, and that is why you get a price after them rather than before.
- Out of that tank comes the tainted mix: that tank is emptied.
- Petrol that has moved beyond the tank sits in your lines once it ran, and the fuel lines are flushed to shift it.
- Your filter is seen to. Cleared, or changed where the vehicle has a workable one.
- Fresh diesel goes in, and the system is primed.
- The start-up. With fresh diesel in and the system primed, it is fired up and checked to confirm it runs correctly.
Your car has fresh diesel running through it before our engineers leave. Long-term damage is very unusual if it has been noticed quickly, so the car can go straight back to normal driving.
Back on the road around Thistleboon after the fuel drain
- Started on fresh diesel, it needs nothing special of you. Just drive normally.
- Watch the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle tells you to pull over and ring us back.
- The work may come up later with a hire firm, an insurer or a fleet manager. Keep your documents.
- Check the label on the petrol pump next time, not the colour of its handle.
