Petrol in Diesel

What Happens Now: Petrol in a Diesel Car in Castleton Park

Pause, and leave your motor off — not on, and not for a moment to shift the car. The next few minutes decide it far more than anything else: petrol in a diesel that has not run usually comes down to emptying then rinsing, right there. Here is the sequence of things from here, wherever you're in Castleton Park.

Motor off: minute one with petrol in a diesel

In this sequence, all before everything else:

  • The keys out of your ignition. Turning the ignition on can be enough to prime your fuel system, while priming pulls petrol out of your tank toward the parts it harms. Leave the vehicle off altogether.
  • Topping up with diesel seems like it dilutes the problem. It doesn't: nothing comes out, and that tank just carries more of the same.
  • Visibility comes before the rest beside moving traffic: switch the hazards on, and only then think about anything else.
  • By hand, never under your engine: that is how it leaves the pump. Ask the forecourt staff to help you push, however short the mileage.
  • Hold on to your receipt: the fuel and the rough amount are printed on it, and they're what our technicians ask about first.

If you were still driving when you noticed, pull over somewhere safe instead of pushing on for the services — on the M4, under 10 miles from Castleton Park, that means the next junction. Stage one follows.

Has it run yet? The fork in every Castleton Park fuel drain

Everything after this stage rests on one answer.

Not run, not even once:

  • All the petrol sits inside the tank, and only there.
  • A drain and flush, on the spot, is normally the whole job.
  • Stage one matters for precisely this reason: it is the best place to be in.

Run at all, however briefly:

  • Your lines and the fuel filter now hold petrol pulled from the tank.
  • On a bigger run it has got to the high-pressure fuel pump as well as your injectors.
  • Lines flushed, your filter sorted, and sometimes more: the job grows as the miles does.

That line falls there because diesel protects the high-pressure pump and the injectors on its way through them — and petrol does not. In that tank, sitting still, petrol harms nothing. Pump that petrol, though, and it wears the very parts that move it.

Castleton Park, petrol in a diesel: have these ready before you call

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

  • Your whereabouts: a postcode beginning CF62 4 works best.
  • A road name helps: Castleton Road, say, or whatever street you have stopped in. A car park works too.
  • Or the landmark. A car park is quicker to find by what it serves, such as the one outside Co-op Food.
  • Make and model of your car, and the fact it is a diesel.
  • Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Castleton Park page.
  • How much. Litres from your receipt, or how long the nozzle was in.
  • Has it run? If so, tell us how far it went, and the way it was driven.
  • Whose car it is. Some hire and company agreements want the owner to approve this work, and that is easier settled before our engineers get there than after.

Next, 0333 366 0103. Not urgent, the car parked at home with nowhere to be? Then works as well.

While you wait for a fuel drain in Castleton Park

In the wait, the harm comes from kindly meant help — which is why these matter.

  • Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before your car.
  • Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: no one starts it.
  • None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives.
  • A DIY drain leaves your fuel already gone beyond that tank, and siphoning petrol by the road is dangerous too.
  • Leave your ignition off — your windows and your radio included.

Step by step: the fuel drain when our van arrives

  • Three queries. What was put in, how much, and if it's run. The answers shape the job, which is why our price comes after them and not before.
  • That tank is emptied. The tainted mix comes out of that tank.
  • Your lines are flushed. If it ran, that petrol has shifted beyond the tank, and your lines are holding it.
  • The filter is dealt with. Cleared, or swapped where the car has a usable one.
  • The system is primed with fresh diesel.
  • The start-up. With fresh diesel in and your system bled, it's started and checked to make sure it runs smoothly.

The vehicle has new diesel running through it before we go. If it has been noticed early, long-term damage is very unusual, and the vehicle goes back to normal driving straight away.

Castleton Park, after your fuel drain: back on the road

  • Drive normally. There is nothing unusual to do once it's been started on fresh fuel.
  • Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot.
  • An insurer, a fleet manager or a hire company may ask what was carried out, and so keep your documents.
  • The handle's colour is not the guide to go by next time — the label on the pump is.
