Matthewsgreen: Petrol in a Diesel Car? Here Is What Happens
Not for a moment, and not for moving it: the engine remains off. Pause there. Petrol in a diesel that hasn't been run is generally a drain plus a flush, done right where your vehicle stands, and what you do in the next few minutes decides that far more than anything else. Wherever you happen to be around Matthewsgreen, this is the order things go from now.
Minute one: petrol in a diesel, motor off
First, these — in this order.
- Take the keys out. Even your ignition by itself can prime the system, pulling petrol out of your tank to precisely the components it harms, so keep the vehicle off entirely.
- Topping up with diesel seems like it thins the issue. It doesn't: nothing comes out, and your tank simply carries more of the same.
- Get the vehicle simple to see before anything else — hazards on — if there is moving traffic anywhere near you.
- However short the distance, starting it to shift it is the mistake. On a forecourt, push the vehicle clear of the petrol pump by hand instead, then ask the attendants to help.
- Which fuel, and roughly how much? Your receipt answers both, and that is where our questions start. Do not bin it.
If you were still driving when you noticed, pull over somewhere safe rather than pushing on for the services — on the A329(M), under a mile from Matthewsgreen, that means the next junction. Step one comes next.
Matthewsgreen fuel drain: has your engine run yet, or not?
One answer is what everything after this point depends on.
Engine not run at all?
- The petrol remains in that tank, and just there.
- Normally it's drained and rinsed right where your car stands.
- Stage one counts for exactly this reason: it is the best spot to be in.
If it has been started, even for a moment:
- The lines and the fuel filter now carry petrol pulled out of the tank.
- Run it farther and that petrol reaches the fuel injectors, having passed through your fuel pump first.
- Lines flushed, the filter dealt with, occasionally more: this job expands as the miles does.
Petrol does not lubricate. Diesel does, oiling the pump and injectors as it passes through, which is why the line sits where it does. In that tank, left alone, petrol does no harm. Once it is pumped, petrol starts grinding whatever moves it.
Calling about petrol in a diesel from Matthewsgreen: what to have prepared
Whether the technician goes round or finds you depends on a little preparation.
- The best place to start is a postcode — one beginning RG41 1 — for where you have stopped.
- A road name is a help: Cantley Crescent, say, or whichever street you've stopped in. A car park works too.
- Describe a car park by what it serves — the one outside Morrisons, for example — and it is far quicker to find.
- That it is a diesel, plus the make and model of the car.
- Which went in counts: AdBlue is a separate job from petrol, plus Matthewsgreen has a page for it. So say.
- The quantity: the receipt's litres, or otherwise how long you had the nozzle in.
- The distance it did, and how hard, if it has run at all.
- Hire or company car? Some agreements want the owner's authorisation for the work, and getting it before we arrive is quicker than afterwards.
Phone 0333 366 0103 next. Writing to is fine too if it can wait, with your car parked at home, going nowhere.
The wait for a Matthewsgreen fuel drain, and what to do in it
The wait is where well-meant help does the harm. Hold to these.
- Safety before the car. If it has stopped somewhere unsafe, get yourself clear of the traffic then wait away from it. If it's safe where it stands, stay with it.
- A helpful passer-by does not start it. Nor does anyone wanting to check it still does the trick, or rolling it a few yards.
- Something from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.
- A DIY drain leaves the fuel that has already gone beyond your tank, and siphoning petrol by the road is risky besides.
- Leave your ignition off — your windows and your radio too.
The fuel drain, step by step, after our van gets there
- Our quote comes after three questions, not before them — what got in, how much, and if it's run — because those answers decide the job.
- Your tank is drained. The polluted mixture comes out of the tank.
- The lines are cleaned. If it ran, the petrol has moved beyond that tank, and the lines are carrying it.
- Cleaned, or changed if the car has a serviceable one: your filter is sorted next.
- Priming follows after fresh diesel is in.
- We fire it up only after clean diesel has gone in and primed your system, then make sure that it's running correctly.
Only once it's running on new diesel do we leave. The vehicle goes back to normal driving right away, and long-term damage is very unusual when it has been caught early.
Matthewsgreen, after the fuel drain: back on the road
- Nothing unusual is needed after a start with fresh diesel — normal driving is all.
- Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over and ring us back.
- Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was carried out.
- Next time, go by the pump's label rather than the colour of its handle.
