Send Marsh: Petrol in a Diesel Car? Here Is What Happens
Stop. Motor off. Leave it like that — no moment on, no shifting it anywhere. Petrol in a diesel that has not been run is generally a drain plus a flush, done right where your car sits, and what you do in the next few minutes settles that more than anything else. Here is the sequence of things from now, wherever you're around Send Marsh.
Petrol in a diesel, engine off — the first minute
Before anything else, the following — following this sequence.
- The keys out of the ignition. Turning your ignition on can be all it takes to prime the fuel system, and priming pulls petrol out of the tank towards the components it damages. Leave the car off completely.
- Topping up with diesel seems like it thins the problem. It does not: nothing gets out, and that tank simply holds more of the same.
- Get the car easy to see first — hazards on — if there's moving traffic anywhere close to you.
- By hand, never on your engine: that's how it comes off the petrol pump. Ask the forecourt attendants to help you push, whatever the mileage.
- Which fuel, and about how much? Your receipt replies that, and that's where our questions start. Never bin it.
On the M25, under 5 miles from Send Marsh, the next junction is the place to leave it; anywhere, the first safe location to stop. Don't push on to the services. Then go back to stage one.
The fork in each Send Marsh fuel drain: has it run yet?
Everything after this stage depends on one answer.
If it has not once been started:
- Nowhere but the tank: that's where the petrol still is.
- Draining and flushing, on the spot, is normally the whole job.
- This is the best spot to be in, and the reason step one matters.
Motor run, however for a moment?
- Petrol has been pulled out of your tank, past your filter then into the lines.
- Run it farther and the petrol gets to the injectors, having passed through your fuel pump first.
- The farther it went, the bigger the job — your lines, your filter, and sometimes more besides.
Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. A tank of petrol, left alone, hurts nothing. As soon as it's pumped, petrol begins wearing down whatever moves it.
What to have prepared when you call about petrol in a diesel from Send Marsh
Whether the technician circles or finds you comes down to a little planning.
- Where you have stopped. A postcode starting GU23 6 is the best start.
- Wherever you have parked, the road's name is useful — whether that is Polesden Lane or somewhere else — and so does the name of a car park.
- Name a car park by what it serves — the one at Little Waitrose, for instance — and it is much easier to find.
- Tell us what your vehicle is — make, model — and check it is diesel.
- Say which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Send Marsh.
- How much. Litres from the receipt, or how long the nozzle was in the filler.
- If it has run, how far plus how heavily — as well as if it's run at all.
- Whose motor it is. Some hire or company agreements want the owner to authorise this work, and that is easier settled before our technicians get there than after.

Waiting for a fuel drain in Send Marsh: what to do
Help, however well meant, is the thing that does the harm whilst you wait. So stick to these.
- Wait with the vehicle if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.
- No one — however kind — starts it, whether to see if it runs or to move the vehicle a short way.
- Anything from the boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol.
- Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays put regardless.
- Not for your radio, not for the windows: the ignition remains off.
Step by step: your fuel drain when the van gets there
- First, three questions: which fuel got in, the quantity, and has it run? Those replies shape the job, and so our price follows them.
- That tank is cleared. The contaminated mixture comes out of that tank.
- Petrol that has shifted beyond the tank sits in the lines once it ran, and the fuel lines are rinsed to clear it.
- Where the vehicle has a usable filter, it's changed; if not, cleared.
- Fresh diesel goes in, and your system is primed.
- Our technicians fire it up only after clean diesel has gone in and primed the fuel system, then confirm that it is running smoothly.
Only when it is running on fresh diesel do our technicians leave. If it has been caught early, long-term damage is very unusual, and the vehicle goes back to normal use straight away.
Send Marsh, after your fuel drain: back on the road
- Once it's been started on fresh fuel, there is nothing special to do: drive normally.
- Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over and ring us back.
- Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Next time, trust the petrol pump's label rather than the colour of its handle.
