Renfrew: Petrol in a Diesel Car? Here Is What Happens
Not for a moment, and not for moving it: the engine stays off. Pause there. Cleared then rinsed, just where it is: that is usually all an unrun diesel with petrol in it needs. Whether it stays that simple depends on the minutes ahead more than on anything else. Here is the sequence of things from now, wherever you are in Renfrew.
Petrol in a diesel, motor off — the first minute
Work through these in order, before you do anything else.
- Bleeding the system pulls petrol from the tank toward the parts it damages, and switching the ignition on can be enough to do that. So the keys come out, and your ignition remains off completely.
- No diesel on top. More fuel in takes away none of that petrol — it just leaves you with extra of the same mixture.
- Visibility comes before the rest beside moving traffic: switch the hazard lights on, and only then deal with everything else.
- However short the distance, starting it to shift it is the thing to avoid. At a forecourt, roll it away from the petrol pump by hand instead, and ask the attendants to lend a hand.
- Which fuel, and roughly how much? The receipt replies both, and that is where our questions start. Never throw it away.
Still on the move when you noticed? Come off the M8 at the next exit if that's where you are, under a mile from Renfrew, and pull over somewhere safe and not pressing on to the services. Then start at step one.
Has it run yet? The fork in each Renfrew fuel drain
One answer is what everything after this point rests on.
Motor never run at all?
- Only that tank has petrol in it so far.
- Normally it is drained and rinsed right where the vehicle is.
- This is as good as it gets — which is the entire point of step one.
If it has been started, even for a second:
- Out of that tank, through your filter, into the lines: that is how far the petrol has got.
- Run it further and that petrol reaches the injectors, having gone through your pump first.
- Distance is what makes it a larger job: flushed lines, a filter seen to, and at times further work.
The reason the line falls there: diesel protects the high-pressure fuel pump as well as the injectors as it passes through them, and petrol does not. In that tank, sitting still, petrol does no harm. As soon as it's pumped, petrol begins grinding whatever moves it.
Before you call about petrol in a diesel in Renfrew: what we need
Whether the technician goes round or finds you comes down to a little preparation.
- Your whereabouts: a postcode starting PA4 8 works best.
- A road name helps: South Deeside Road, say, or whatever street you've stopped in. A car park does the trick too.
- Describe a car park by what it serves — the one outside Aldi, for example — and it is much easier to find.
- The car. Make, model, plus that it is a diesel.
- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Renfrew page.
- Roughly how much — in litres from your receipt, or by how long the nozzle was in.
- Has it run? If so, tell us how far it got, and the way it was driven.
- Whose motor it is. Some hire or company agreements want the owner to authorise this work, and that's easier settled before we turn up than after.
Phone 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use .
Renfrew fuel drain on its way? Whilst you wait
Stick to these: kindly meant help causes the harm during the wait.
- Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it is safe where it sits, stay with it.
- Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a couple of yards.
- Additives stay in the boot. Injector cleaner and two-stroke oil take none of that petrol out once more.
- Siphoning petrol into a can by the roadside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain.
- Not for the radio, not for the windows: your ignition stays off.
When the van gets there: the fuel drain, step by step
- Three queries. What went in, how much, and if it has run. Those replies set this job, which is why our price comes after them but not before.
- Next that tank is emptied, so the contaminated fuel comes out.
- If it ran, the fuel lines are holding petrol that has moved beyond that tank — so they are cleaned.
- Cleaned, or replaced if the car has a serviceable one: the fuel filter is dealt with next.
- Fresh diesel goes in, then your system is primed.
- Our engineers start it only after new diesel has gone in and bled your system, then make sure that it is running correctly.
Only when it is running on new diesel do our technicians head off. It's very rare for a vehicle caught quickly to be left with long-term damage, and normal driving starts again at once.
Back on the road around Renfrew after the fuel drain
- Nothing special is needed after a start with fresh diesel — ordinary driving is all.
- Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over then call us back.
- The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- The handle's colour isn't the thing to go by next time — the label on the petrol pump is.
