St Andrew: Petrol in a Diesel Car? Here Is What Happens

Not for a moment, and not to move it: your motor remains off. Pause there. Drained and flushed, right where it is: that is usually all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes to come more than on everything else. Wherever you happen to be in St Andrew, this is the order things run from here.

Petrol in a diesel? What to do in minute one

Do these first, in this sequence.

  • The keys out of the ignition. Switching your ignition on can be all it takes to prime the system, while priming draws petrol out of your tank toward the parts it harms. Leave the car off altogether.
  • A bigger tank of the same mix is all topping up gives you, since it takes out nothing. So no extra diesel.
  • Close to passing traffic? Then your hazards come on before anything else, so your car is simple to spot.
  • The staff will normally help you push it away from the petrol pump. Ask, and roll it by hand — not under your engine, even for a few yards.
  • Which fuel, and about how much? The receipt replies that, and that is where our first question starts. Never throw it away.

Noticed on the move? Get off at the next exit if you're on the M5, under 15 miles from St Andrew, and pull over somewhere safe — not at the services farther on. Stage one starts after that.

Has it run yet? The fork in each St Andrew fuel drain

Everything after this point rests on one answer.

If the engine hasn't run at all:

  • All the petrol sits in that tank, and just there.
  • Draining and flushing, on the spot, is normally the whole job.
  • Being here is the best case — which is the whole point of stage one.

If it's been started, even for a moment:

  • Petrol has been drawn from that tank, through the filter then into the lines.
  • On a bigger run it has reached the high-pressure pump and the injectors.
  • Lines flushed, your filter seen to, occasionally more: this job expands as the miles does.

Why the line falls there: diesel protects your high-pressure pump and the fuel injectors as it passes through them, and petrol doesn't. Petrol sitting in a tank damages nothing. Move that petrol, though, and it wears the very parts that move it.

Calling about petrol in a diesel from St Andrew: what to have ready

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

  • BA5 2 plus the rest of the postcode makes the best way to begin telling us where you are.
  • The street or the car park. A road name is a help — St Andrews Street, or wherever you have pulled up.
  • Name a car park by what it serves — the one at Budgens, for instance — and it's much quicker to find.
  • Make and model of the car, and the fact it is a diesel.
  • Which got in counts: AdBlue is a separate job from petrol, plus St Andrew has a page for it. So tell us.
  • About how much — in litres from the receipt, or by how long the nozzle was in.
  • If it's run, how far and how hard — and if it has run at all.
  • The owner may have to approve this work under some hire or company contracts — which is why it is quicker to settle whose vehicle it is before our technicians get there.

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

Waiting for a fuel drain in St Andrew: what to do

The wait is where well-meant help does the damage. Stick to these.

  • Where your car has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car.
  • No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a few yards.
  • Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol.
  • No DIY emptying. Siphoning petrol into a can by the roadside is hazardous, and it leaves your fuel that has already gone beyond that tank.
  • Not for your radio, not for the windows: the ignition stays off.

When our van arrives: your fuel drain, step by step

  • Three queries. What went in, how much, and if it's run. The answers shape this job, which is why the quote comes after them but not before.
  • Draining it's how the blend gets taken out of your tank.
  • If it ran, your lines are holding petrol that has moved beyond your tank — so they're purged.
  • Where the vehicle has a serviceable filter, it's replaced; if not, cleared.
  • Clean diesel in, and the fuel system primed.
  • Starting the car. After your system is bled with fresh diesel, we start it and confirm it runs properly.

Your car has clean diesel running through it before we go. When it has been spotted quickly, lasting damage is very unusual, and the vehicle goes back to normal driving straight away.

Once the fuel drain is done: driving around St Andrew a second time

  • After it has been started on fresh fuel, there's nothing special to do: drive normally.
  • The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop and call us again.
  • Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
  • Next time, go by the petrol pump's label rather than the colour of its handle.
