# Petrol in a Diesel Car in Stotfold: What Happens Now

Whatever you do, never switch the motor on, even for a moment, to shift it. Stop; leave the car off.

Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever your car has stopped — and no other factor decides that as much as these next few minutes do.

Anywhere you are around Stotfold, this is the order things run from now.

## Petrol in a diesel? What to do in minute one

In this sequence, and before anything else:

- Priming your fuel system draws petrol from your tank towards the components it harms, and switching your ignition on can be enough to do that. So the keys come out, and the ignition stays off altogether.

- Topping up with diesel sounds like it thins the issue. It doesn't: nothing comes out, and the tank just carries more of the same.

- Make your car easy to see before anything else — hazard lights on — if there is traffic going past anywhere near you.

- However short the distance, starting it to move it is the mistake. On a forecourt, push the car clear of the pump by hand instead, and ask the attendants to lend a hand.

- Hold on to the till receipt. It shows which fuel was put in plus about how much, which is the first thing we'll ask.

If you were still driving when you noticed, stop somewhere safe instead of pushing on for the services — on the A1(M), under 3 miles from Stotfold, that means the next exit. Step one follows.

## Stotfold fuel drain: has your motor run yet, or not?

From this stage on, everything hinges on a single answer.

If the motor hasn't run at all:

- Just that tank has petrol in it so far.

- Usually it is drained and flushed just where the car is.

- No spot is better, and it's why the first step counts so much.

Engine run, however briefly?

- Petrol has been drawn from that tank, through the fuel filter then into your lines.

- Run it farther and that petrol reaches the fuel injectors, having passed through your pump first.

- Distance is what turns it into a larger job: the lines flushed, a filter seen to, and at times further work.

The reason the line falls there: diesel protects the high-pressure fuel pump as well as the injectors as it flows through them, and petrol doesn't.

In the tank, left alone, petrol harms nothing.

Petrol being pumped is wearing the components that shift the vehicle.

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

Prepare a little, and the technician finds you rather than circling.

- Where you have stopped. A postcode starting SG5 4 is the best start.

- A road name helps: Hitchin Road, say, or whichever street you've stopped in. A car park does the trick too.

- Name a car park by what it serves — the one at The Co-operative Food, for instance — and it is much easier to find.

- That it's a diesel, plus the make and model of your vehicle.

- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Stotfold page.

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

- The mileage it covered, and how heavily, if it has run at all.

- The owner may have to authorise the work under some hire or company agreements — so it is faster to settle whose motor it is before we get there.

Next, 0333 366 0103. Not time-critical, the vehicle parked at home with nowhere to be? Then  will do too.

## Stotfold fuel drain on its way? While you wait

In the wait, the harm comes from well-meant help — so these matter.

- Wait with the car if it is safe where it is — but if it has stopped somewhere dangerous, 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 moving it a few yards.

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

- Siphoning petrol into a can by the roadside is dangerous — and it still leaves whatever fuel has already gone beyond your tank. Do not try a home-made drain.

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

## Van arrived? The fuel drain, one stage at a time

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

- Draining it's how the mixture gets taken out of the tank.

- If it ran, the lines are carrying petrol that has shifted beyond the tank — so they're cleaned.

- The fuel filter is dealt with. Cleared, or replaced where your car has a serviceable one.

- Clean diesel in, and the fuel system primed.

- The start. With clean diesel in and the fuel system bled, it is fired up and checked to confirm it runs properly.

Until it runs on clean diesel, our technicians stay with it.

It's very uncommon for a car spotted early to be left with permanent damage, and normal use starts again at once.

## After the fuel drain is done: driving around Stotfold a second time

- Nothing special is needed after a start with clean diesel — ordinary driving will do.

- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then ring us back.

- An insurer, a fleet manager or a hire firm may ask what was done, and so keep your documents.

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