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

Whatever you do, don't switch the engine on, even briefly, to shift the vehicle. Stop; leave the vehicle off.

Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and nothing settles that more than the next few minutes do.

What follows is the sequence from this point, wherever in Exwick you happen to be.

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

In this sequence, all before everything else:

- Take your keys out. Even your ignition by itself can prime your fuel system, pulling petrol out of the tank to precisely the components it harms, and so leave it off entirely.

- Do not top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture.

- Being seen comes before the rest near moving traffic: put the hazard lights on, and only then deal with everything else.

- However short the way, starting it to move it is the mistake. At a forecourt, roll it away from the pump by hand instead, and ask the attendants to help.

- Keep your receipt. It says which fuel was put in plus roughly how much, which is the first thing we'll ask.

Realised on the move? Get off at the next junction if you're on the M5, under 5 miles from Exwick, and pull over somewhere safe — not at the services farther on. Stage one comes after that.

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

One answer is what everything after this point rests on.

Not run, not even once:

- The petrol is still inside that tank and nowhere else.

- Usually it is emptied and flushed right where the car stands.

- No position is better, and it is why the first stage counts so much.

Run at all, however briefly:

- From your tank, through the filter, into the lines: that's how far that petrol has travelled.

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

- Lines flushed, the filter seen to, occasionally more: the job expands as the mileage does.

The reason the line falls there: diesel protects the high-pressure fuel pump as well as your injectors as it passes through them, and petrol does not.

A tank of petrol, left alone, hurts nothing.

Petrol being pumped is grinding down the parts that shift it.

## What to have prepared when you call about petrol in a diesel from Exwick

A technician that circles against a van that finds you: a little preparation is the difference.

- Where you have stopped. A postcode starting EX4 2 is the best place to start.

- A road name is a help: Valley Road, say, or whatever street you've stopped in. A car park works too.

- Name a car park by what it serves — the one at Tesco Express, for instance — and it's much easier to find.

- Say what your vehicle is — make, model — and confirm it is diesel.

- Tell us which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Exwick.

- How much. Litres from the receipt, or how long the nozzle was in.

- Has it run? If so, tell us how far it got, and the way it was driven.

- Whose vehicle it is. Some hire or company agreements want the owner to authorise this work, and that's quicker settled before we arrive than after.

Phone 0333 366 0103 next. Writing to  is fine too if it can wait, with your car parked at home, going nowhere.

## The wait for a Exwick fuel drain, and what to do in it

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

- Your safety comes before the vehicle. Somewhere unsafe? Get away from the traffic then wait away from it. Safe where it is? Wait with it.

- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards.

- Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out again.

- Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank remains put regardless.

- Leave your ignition off — your windows and the radio too.

## Step by step: the fuel drain when the van arrives

- Three questions. What went in, how much, and whether it has run. The replies set the job, which is why the quote comes after them and not before.

- Out of your tank comes the tainted mix: the tank is drained.

- Your lines are purged. If it ran, that petrol has shifted beyond the tank, and the fuel lines are carrying it.

- Where the vehicle has a usable filter, it is replaced; otherwise, cleared.

- Bleeding the system follows once fresh diesel is in.

- We start the car only after new diesel has gone in and bled the system, then make sure that it is running correctly.

Our technicians remain until it's running on clean diesel.

The car returns to normal use straight away, and permanent damage is very rare if it has been spotted soon.

## After your fuel drain: back on the road in Exwick

- Started on fresh diesel, it needs nothing unusual of you. Simply drive normally.

- Watch the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over then ring us back.

- The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.

- Next time, trust the petrol pump's label rather than the colour of its handle.

## Leave it off and ring: petrol in a diesel around Devon

Petrol in Diesel takes it from there — on your driveway, by the roadside, on the forecourt — once you've done stage one: keys out, motor off, receipt in your pocket.
