Cockfield: Petrol in a Diesel Car? Here Is What Happens

Whatever you do, never switch your engine on, even for a moment, to move it. Stop; leave it off. Cleared then rinsed, just where it sits: that's normally all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes to come more than on anything else. Here's the order of things from now, anywhere you're in Cockfield.

Petrol in a diesel? What to do in minute one

First, these — in this order.

  • Keys out of the ignition. Turning your ignition on can be all it takes to prime your fuel system, while priming draws petrol out of your tank towards the parts it damages. Keep the vehicle off completely.
  • Topping up with diesel seems like it thins the trouble. It doesn't: nothing gets out, and that tank simply carries more of the same.
  • Close to moving traffic? Then the hazards come on before anything else, so the car is simple to see.
  • By hand, never under the motor: that's how it leaves the petrol pump. Get the forecourt attendants to help you push, however short the miles.
  • Keep your receipt: the fuel and roughly how much are written on it, and they're what we ask for first.

If you were still on the move when you realised, stop somewhere sensible rather than pushing on for the services — on the A1(M), under 10 miles from Cockfield, that means the next exit. Stage one comes next.

Has it run yet? The fork in every Cockfield fuel drain

What comes next turns on one answer, and just one.

If your engine hasn't run at all:

  • Only your tank has petrol in it so far.
  • The work is a simple drain and a flush, usually done where the vehicle stands.
  • Step one counts for exactly this reason: it is the best spot to be in.

If the motor has been run, even for a moment:

  • Petrol has been drawn out of that tank, past the filter and into the lines.
  • Run it farther and the petrol reaches your injectors, having passed through the pump first.
  • The farther it went, the larger the job — your lines, your filter, and sometimes more besides.

The reason the line falls there: diesel lubricates your high-pressure pump as well as the fuel injectors as it passes through them, and petrol doesn't. In that tank, left alone, petrol does no harm. As soon as it is pumped, petrol starts wearing down whatever moves it.

Fuel drain of a diesel car in Cockfield, step by step

Before you call about petrol in a diesel in Cockfield: what our engineers need

Get ready a little, and the van finds you rather than circling.

  • DL13 5 plus the rest of the postcode is the best way to start telling us where you are.
  • Name the road — Staindrop Road or wherever you have stopped — or the car park.
  • Car parks are located most easily by what they serve: tell us the one at Tesco Extra, and it is easy.
  • Say what the vehicle is — make, model — and check it is diesel.
  • Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Cockfield page.
  • How long the nozzle was in, or the litres from your receipt — either tells us how much.
  • If it has run, how far plus how heavily — as well as if it's run at all.
  • Whose car it is. Some hire or company agreements want the owner to authorise this work, and that is easier settled before we arrive than after.

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

While you wait for a fuel drain in Cockfield

The wait is where kindly meant help does the harm. Hold to these.

  • Stay with the vehicle if it's 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 favour: no one starts it.
  • Something from your boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol.
  • A DIY drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides.
  • Keep your ignition off — your windows and your radio included.

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

  • Three queries. What was put in, how much, and whether it's run. Those answers decide the job, which is why the price comes after them and not before.
  • That tank is drained. The contaminated mixture comes out of that tank.
  • Petrol that has moved beyond the tank sits in the lines if it ran, and your lines are flushed to shift it.
  • Then your filter: changed where there's a workable one, cleared where there is not.
  • Clean diesel goes in, and the system is primed.
  • The start-up. With clean diesel in and the system primed, it's fired up and tested to be sure it runs correctly.

Only once it's running on clean diesel do our engineers go. If it has been spotted early, long-term damage is very unusual, and the car returns to normal driving right away.

Back on the road around Cockfield after your fuel drain

  • Once it's been started on clean fuel, there's nothing unusual to do: drive normally.
  • The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop then call us a second time.
  • Keep the documents. A hire firm, a fleet manager or an insurer may ask what was done.
  • The handle's colour isn't the guide to go by next time — the label on the pump is.
