The Next Steps, in Order: Petrol in a Diesel Car in St Thomas
Stop. Engine off. Leave the vehicle like that — no moment on, no moving it anywhere. Emptied then cleaned, just where it is: that is generally all an unrun diesel with petrol in it needs. Whether it remains that simple rests on the minutes to come far more than on anything else. From now on, step by step, wherever you are around St Thomas:
Engine off: minute one with petrol in a diesel
First, the following — in this sequence.
- The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank into the parts it damages.
- Don't top it up with diesel. Adding diesel removes nothing. You are left with a fuller tank of the same mixture.
- Being seen comes first near moving traffic: switch the hazards on, and only then deal with anything else.
- The attendants will generally help you push it clear of the pump. Let them, and roll it by hand — never on the engine, even for a few yards.
- Keep the receipt: the grade and the rough amount are written on it, and they are what we ask about first.
If you were still driving when you noticed, stop somewhere sensible rather than pushing on for the services — on the M5, under 50 miles from St Thomas, that means the next exit. Stage one follows.
St Thomas fuel drain: has your motor run yet, or not?
One answer is what everything after this stage rests on.
If it has not once been started:
- Nowhere but your tank: that's where the petrol yet is.
- Where the car stands is usually where the work happens: a drain, then a flush.
- This is the best spot to be in, and the whole reason step one matters.
If the motor has run, even for a moment:
- Some petrol has left your tank already, gone through your filter, and reached your lines.
- The high-pressure fuel pump and your injectors get it on a bigger run.
- Lines flushed, the filter sorted, and sometimes more: the job grows as the mileage does.
Diesel keeps the high-pressure fuel 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, sitting still, petrol harms nothing. Move that petrol, though, and it grinds down the very parts doing the moving.
Calling about petrol in a diesel from St Thomas: what to have prepared
A technician that circles against a technician that finds you: a little planning is what separates them.
- PL15 8 plus the rest of the postcode is the best way to start telling us where you are.
- A road name helps: Priory Mews, say, or whichever street you have stopped in. A car park does the trick too.
- Car parks are found most easily by what they serve: say the one outside The Co-operative Food, and it's straightforward.
- Say what your vehicle is — make, model — and check it's diesel.
- Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for St Thomas.
- How much. Litres from the receipt, or how long the nozzle was in the filler.
- Has it run? If so, tell us how far it went, and the way it was driven.
- Whose vehicle it is. Some hire and company contracts want the owner to authorise this work, and that is quicker settled before our engineers turn up than after.

The wait for a St Thomas fuel drain, and what to do in it
Help, however well meant, is what does the harm while you wait. So stick to these.
- Stay with the car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
- Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: nobody starts it.
- None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives.
- Siphoning petrol into a can by the kerbside is hazardous — and it also leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain.
- Even your radio or the windows aren't worth turning your ignition on for.
Step by step: your fuel drain when our van arrives
- First, three questions: which fuel went in, the quantity, and has it run? Those answers shape this job, and so our quote follows them.
- The tank is emptied. The tainted mix comes out of the tank.
- Your lines are cleaned. If it ran, the petrol has shifted beyond your tank, and the lines are holding it.
- Then the filter: changed where there's a usable one, cleared where there is not.
- Clean diesel in, and your system primed.
- First start on new diesel. Once priming is done, your engine is fired up and we confirm that it runs smoothly.
Till it runs on clean diesel, we stay with it. If it has been caught soon, long-term damage is very uncommon, and the vehicle goes back to normal driving right away.
St Thomas, after your fuel drain: back on the road
- Drive normally. There is nothing unusual to do after it has been started on fresh fuel.
- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and ring us again.
- An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to your documents.
- Check the label on the pump next time, not the colour of its handle.
