Tremorfa: Petrol in a Diesel Car? Here Is What Happens
Not for a moment, and not to move it: the motor remains off. Pause there. The coming few minutes settle it more than anything else: petrol in a diesel still unrun usually comes down to emptying then purging, right there. Below is the order from this point, wherever around Tremorfa you are.
Petrol in a diesel? What to do in minute one
In this sequence, all before everything else:
- The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of your tank into the components it harms.
- Topping up with diesel sounds like it dilutes the issue. It doesn't: nothing gets out, and that tank simply carries more of the same.
- Hazards on. If you're at all near moving traffic, make the car easy to see before you do anything else.
- Off the petrol pump by hand. At a forecourt, ask the staff to help you roll the vehicle clear of the petrol pump. Don't start it to shift it, however short the distance.
- Hold on to the receipt. It shows which fuel went in plus roughly how much, which is the first thing we'll ask.
Still driving when you noticed? Come off the A48(M) at the next exit if that's where you are, under 5 miles from Tremorfa, and pull over somewhere safe instead of pushing on to the services. Then begin at step one.
The fork in every Tremorfa fuel drain: has it run yet?
From this point on, everything hinges on a single answer.
Motor not run at all?
- No place but your tank: that is where that petrol yet is.
- Usually it is drained and flushed just where the car stands.
- No position is better, and it is why the first stage matters so much.
If it has been started, even for a moment:
- The fuel lines and the fuel filter now hold petrol pulled out of the tank.
- A longer run carries it all the way to the high-pressure pump and the injectors.
- The further it went, the larger this job — your lines, the fuel filter, and sometimes more besides.
Diesel keeps the high-pressure fuel pump and the injectors oiled as it goes through them. Petrol offers them nothing, and that is why the line is drawn there. In your tank, left alone, petrol harms nothing. The parts that shift it are grinding the moment petrol is being pumped.
Tremorfa, petrol in a diesel: have these prepared before you call
Prepare a little, and the van finds you rather than circling.
- The best start is a postcode — one starting CF24 2 — for where you have stopped.
- The street or the car park. A road name is a help — Dessmuir Road, or wherever you have pulled up.
- Name a car park by what it serves — the one outside ALDI, for instance — and it's much quicker to find.
- The vehicle. Make, model, and that it is a diesel.
- Tell us which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Tremorfa.
- The quantity: your receipt's litres, or otherwise how long you had the nozzle in.
- Whether it's run. And if it has, how far plus how hard.
- Whose motor it is. Some hire or company agreements want the owner to approve this work, and that is easier settled before our technicians get there than after.
Phone 0333 366 0103 once you've got that ready — or, if your car is at home, going nowhere, use .
Tremorfa fuel drain on its way? While you wait
During the wait, the harm comes from well-intended help — which is why these count.
- Stay with the car 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 couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it.
- None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives.
- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank stays put regardless.
- Not for the radio, not for your windows: the ignition stays off.
Step by step: your fuel drain when our van arrives
- Fuel, quantity, whether it has run: the replies set this job, and that is why you get a quote after them rather than before.
- That tank is cleared. The contaminated blend comes from your tank.
- Cleaning your lines comes next, because a car that ran has petrol past the tank, in the fuel lines themselves.
- The fuel filter is dealt with. Cleared, or replaced where the vehicle has a workable one.
- Fresh diesel in, and your system primed.
- Our engineers start it only after fresh diesel has gone in and primed your system, then confirm that it's running correctly.
Till it runs on clean diesel, our engineers remain with it. It is very uncommon for a car spotted soon to be left with long-term damage, and normal driving starts again right away.
After the fuel drain: back on the road in Tremorfa
- Nothing unusual is needed after a start with clean diesel — normal driving is all.
- Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from the exhaust, an idle that is lumpy, or a throttle with a dead spot.
- Keep your paperwork. 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.
