Tyntetown: Petrol in a Diesel Car? Here Is What Happens
Whatever you do, don't switch the motor on, even briefly, to move the car. Pause; leave the car off. Petrol in a diesel that has not been run is usually a drain and a flush, done where your car sits, and what you do in the coming few minutes settles that more than anything else. Here is the sequence of things from here, anywhere you're in Tyntetown.
Minute one: petrol in a diesel, motor off
Before anything else, these — following this sequence.
- Bleeding the system draws petrol from your tank towards the components it damages, and switching the ignition on can be enough to do that. So your keys get taken out, and your ignition remains off completely.
- Topping up with diesel sounds like it dilutes the problem. It does not: nothing gets out, and that tank simply carries more of the same.
- Being seen comes before the rest near moving traffic: put your hazards on, and only then deal with everything else.
- By hand, never under the motor: that's how it leaves the petrol pump. Ask the forecourt attendants to help you roll, whatever the mileage.
- Hold on to the till receipt. It says which fuel was put in plus roughly how much, which is the first thing we will ask.
On the M4, under 15 miles from Tyntetown, the next exit is the location to come off; anywhere, the first safe place to stop. Do not press on to the services. Then go back to step one.
Tyntetown fuel drain: has your motor run yet, or not?
What comes after this turns on one answer, and only one.
Engine not run at all?
- The petrol remains in the tank, and just there.
- Normally it's emptied and rinsed right where your car stands.
- This is the best case — which is the entire point of step one.
If it has been started, even for a second:
- Some petrol has left that tank by now, passed through the fuel filter, and reached the lines.
- On a longer run it has got to the high-pressure fuel pump and your injectors.
- The job expands with the mileage — lines flushed, filter seen to, occasionally more.
That line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol does not. A tank of petrol, left alone, hurts nothing. As soon as it is pumped, petrol begins grinding whatever moves it.
Before you call about petrol in a diesel in Tyntetown: what our technicians need
Prepare a little, and the van finds you instead of circling.
- Your location: a postcode starting CF45 4 works best.
- A road name helps: Pentwyn Avenue, say, or whichever street you have stopped in. A car park works too.
- What a car park serves is the easiest way to find it, so say the landmark — such as the one at Co-op Food.
- The vehicle. Make, model, plus that it is a diesel.
- Say which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Tyntetown.
- How much. Litres from your receipt, or how long the nozzle was in.
- If it has run, how far and how heavily — and whether it's run at all.
- The owner may have to authorise the work under some hire and company agreements — so it is quicker to settle whose car it is before our technicians arrive.
Ring 0333 366 0103 then. Writing to is fine too if it can wait, with the car parked at home, going nowhere.
Waiting for a fuel drain in Tyntetown: what to do
In the wait, the damage comes from well-meant help — which is why these matter.
- Your safety comes before your car. Somewhere dangerous? Get clear of the traffic then wait away from it. Safe where it sits? Wait with it.
- A helpful passer-by doesn't fire it up. Nor does anyone checking it still works, or rolling it a couple of yards.
- No additives. Two-stroke oil, injector cleaner, something from your boot — none of that gets that petrol back out.
- Siphoning petrol into a can by the roadside is risky — and it also leaves whatever fuel has already gone beyond your tank. Do not try a home-made drain.
- Not for your radio, not for your windows: your ignition remains off.
The fuel drain, step by step, once our van gets there
- Fuel, amount, whether it's run: those replies set the job, and that's why we give a quote after them instead of before.
- That tank is emptied. The polluted blend comes out of your tank.
- Petrol that has moved beyond that tank sits in your lines once it ran, and the fuel lines are cleaned to shift it.
- Cleaned, or replaced if your car has a workable one: the filter is seen to next.
- Bleeding the system comes after clean diesel is in.
- Our technicians fire it up only after new diesel has gone in and primed the fuel system, then make sure that it's running correctly.
Until it runs on clean diesel, our technicians stay with it. When it has been noticed early, lasting damage is very unusual, and the car goes back to normal driving straight away.
Tyntetown, after your fuel drain: back on the road
- Started on new diesel, it needs nothing unusual of you. Simply drive normally.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then call us back.
- The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- Next time, check the petrol pump. The label, not the colour of the handle.
