# Trumps Green: Petrol in a Diesel Car? Here Is What Happens

Pause, and keep the motor off — not on, and not for a moment to shift it.

The next few minutes determine it more than anything else: petrol in a diesel still unrun generally amounts to emptying and cleaning, on the spot.

From now on, in order, for anywhere around Trumps Green:

## Engine off: minute one with petrol in a diesel

In this order, and before anything else:

- The 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 parts it harms. Keep the vehicle off altogether.

- Topping up with diesel seems like it dilutes the problem. It does not: nothing comes out, and that tank just holds more of the same.

- Near moving traffic? Then the hazards go on before anything else, and so the car is easy to spot.

- The attendants will normally help you roll it clear of the pump. Ask, then roll it by hand — not on the engine, even for a few yards.

- Keep the till receipt: the fuel and the rough amount are printed on it, and they're what our technicians ask for first.

If you were still driving when you realised, stop somewhere sensible instead of pushing on for the services — on the M3, under a mile from Trumps Green, that means the next junction. Stage one comes next.

## Trumps Green fuel drain: has the engine run yet, or not?

Everything after this point depends on one answer.

Not run, not even briefly:

- All the petrol sits in the tank, and only there.

- The work is a drain and a flush, normally done where the car is.

- This is the best spot to be in, and the whole reason step one matters.

If the motor has been run, even briefly:

- Some petrol has left your tank by now, passed through the fuel filter, and reached the fuel lines.

- A bigger run takes it right through to the high-pressure fuel pump and your injectors.

- Mileage is what turns it into a larger job: the lines flushed, a filter seen to, and at times more than that.

Diesel keeps the high-pressure pump and the injectors protected as it runs through them. Petrol offers them nothing, and that is why the line is drawn there.

Nothing is damaged by petrol that's only waiting in a tank.

As soon as it is pumped, petrol begins wearing whatever moves it.

## What to have ready when you call about petrol in a diesel from Trumps Green

A little preparation is the difference between a van that finds you and a van that goes round.

- The ideal start is a postcode — one starting GU25 4 — for where you are.

- A road name helps: Trumps Green Road, say, or whichever street you've stopped in. A car park works too.

- What a car park serves is the easiest way to find it, and so mention the landmark — like the one outside Co-op Food.

- That it is a diesel, along with the make and model of your vehicle.

- Which got in matters: AdBlue is a separate job from petrol, and Trumps Green has a page for it. So tell us.

- The amount: your receipt's litres, or otherwise how long you held the nozzle in.

- If it has run, how far and how hard — and whether it has run at all.

- Sort who has the vehicle before our technicians arrive: some hire or company contracts want the owner to authorise the work, and doing it faster first.

Phone 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use .

## Trumps Green fuel drain on its way? While you wait

In the wait, the harm comes from well-intended help — which is why these count.

- Wait 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.

- A kind passer-by does not crank it. Nor does anyone checking it still works, or rolling it a couple of yards.

- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that takes that petrol back out.

- A home-made drain leaves the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too.

- The ignition stays off. Even for your radio or your windows.

## When our van arrives: the fuel drain, step by step

- Three queries. What got in, how much, and whether it has run. The replies shape the job, which is why our price comes after them but not before.

- Out of the tank comes the polluted blend: the tank is cleared.

- Petrol that has shifted beyond the tank sits in the lines if it ran, and the lines are rinsed to shift it.

- Then your filter: changed where there is a workable one, cleared where there's not.

- Priming follows after fresh diesel is in.

- Starting the car. After the system is primed with new diesel, we fire it up and make sure it runs correctly.

Till it runs on fresh diesel, our engineers remain with it.

Your car goes back to normal driving at once, and permanent damage is very uncommon if it has been caught early.

## Trumps Green, after your fuel drain: back on the road

- After it has been started on clean fuel, there's nothing unusual to do: drive normally.

- Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.

- Your paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.

- Read the label on the pump next time, not the colour of its handle.
