Petrol in Diesel

Woodmansterne: Put Petrol in a Diesel Car?

If you have not turned on the motor as yet, do not. A drain and nothing else is nearly always what a vehicle needs while the fuel is still sitting in that tank and your engine has not yet been started, which is why it's the coming few minutes that count, not how much went in. Petrol in Diesel travels to the car wherever it has stopped in Woodmansterne or the remainder of Surrey, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. Our team will show you what the next part will be. Contact us — that happens ahead of anything else.

What now? Petrol in a diesel, in turn

  • Never fire it up. Turned on anyway? Then do not depend on it. Diesel in a petrol car normally cannot run, so the driver stops and the wear ends with them. Petrol in a diesel? It starts. It idles. It pulls away normally, for several miles. Most people get that muddled. It isn't fine — that fuel system is wearing every mile you do.
  • Two jobs, diesel: it ignites, and on the way through it keeps that high-pressure fuel pump and injectors greased. Petrol only handles the one. That is why the ignition stays off also — switch it on and you commonly prime that system, and that is petrol leaving your tank for just those parts.
  • Do not put diesel on top to water down it. A diesel fuel system won't tolerate petrol by percentage in the way that advice presumes, and topping up removes nothing — it merely leaves you a fuller tank of the same mixture. The type makes no difference either: super unleaded is simply petrol.
  • We would rather come to an awkward place than have it started — so if you reasonably can, sit tight. Nothing is quicker to sort than a motor that has never shifted. On the verge on Woodmansterne Street, that means hazards on then keep the vehicle.
  • Our van showing up rather than circling turns on two things: a postcode beginning SM7 3, and whatever is closest to you with a sign on it. Have both ready before you call.
  • What went in, roughly how much, and also if your car has fired — these three facts determine the entire job. Ring 0333 366 0103 then tell us.

Clearing petrol from a diesel at a forecourt

It starts at a forecourt, generally. Quite often the work finishes at one too. Our technicians work on station forecourts regularly, with the station's agreement, and so if you are still at Esso that is generally where this drain takes place.

At a garage, this gets stopped with the motor never run, and no place else manages it. We can still sort it out where it sits, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been switched on and driven there, and that sucked fuel through your filter and into the high-pressure pump, all the way from that tank. None of that is a calamity, although the flush then has to reach past your tank to your lines and the fuel filter, and the few seconds between seeing the receipt and going for your key are what determine that.

The attendants will normally offer to roll the vehicle out from the pump so the next motorist can get by. That's worth doing. Cranking it for four car lengths? Don't.

Mobile fuel drain van at a diesel car in Woodmansterne

Any start primes your fuel system and sucks more of that blend out of your tank and toward the pump — which is why a motor shunted twice into a better spot has quietly grown into a bigger job than one left precisely where it stopped. So when our engineers can't work next to the diesel Volkswagen Passat, our engineers shift the car without firing it. None of that is fussiness about a handful of seconds of running. Car parks like the one at Tesco our engineers visit regularly, and your fuel is seldom the awkward part: the bay is. Vehicles either side, a trolley shelter behind, sometimes a height bar at the way in determining if a technician reaches you at all. Tell us how boxed in you are, and which way your car faces.

Your diesel Nissan Qashqai will have seemed completely ordinary on the way back from Woodmansterne Primary School. They always do, and that's the snag with petrol in a diesel rather than the other way round. Put diesel in a petrol car and it mostly will not run, and so the driver stops and the wear stops with them. Put petrol in a diesel and it starts, idles and drives off as though nothing has happened — meanwhile the high-pressure pump works without the lubrication your fuel is meant to be providing. Nothing warns you, as from the driver's seat there's nothing to caution you about. Call us with approximately how far you travelled and how hard you drove it; the second answer matters more than the first.

Simple job, this one — until someone takes it home. A diesel Ford Focus parked by The Woodman with petrol in that tank loses nothing by standing there overnight, so leave the vehicle then phone once it's light. Expect a question about that trip there, though. Brief and chilly is precisely where petrol struggles to burn, and what will not burn can work past the piston rings then into the sump.

Turn off where you have stopped, and don't restart it to find somewhere better — near St Peters Church or anywhere at all. Rattling, a ragged idle, white smoke and a soft throttle are a wrongly fuelled diesel Vauxhall Insignia telling you what's wrong.

A few streets, then it stopped. Throttle limp, idle ragged, and the diesel Volvo XC60 is parked up by Woodmansterne Village Hall. Your engine isn't giving up — that softness is fuel that will not build pressure. There is no light on the dash for it, and so vehicles like yours normally get driven a second time before anyone picks up the phone. Do not. Off, and phone us.

Service near Woodmansterne

Woodmansterne is a rural village, and our team are out to the town and to the places around it on the same trips: Clock House, Little Woodcote, Coulsdon, Banstead and Chipstead.

Not on the list? It says nothing. The places above are just the closest few, and nearly all towns around Surrey have a page of their own elsewhere on the site. Close to the border, or anywhere the satnav struggles with? Call us and enquire instead of assuming.

The map is the area the page covers. Roadside, forecourt, drive, car park: every bit of it is ground we serve, and none of that asks the car to come to us.

Woodmansterne: broken down where you pulled up

Not everyone has a decent place to pull in. Hazards on in a lay-by somewhere, or pulled onto the verge of Chipstead Way as you worked it out after setting off — our technicians take that call regularly enough that it's the usual kind.

Whether you wait beside the vehicle or move away from it hangs on whether sitting in it seems safe. It will often oblige. A diesel running on petrol limps along very willingly, and that's the trouble: start it up to get to somewhere handier and the blend goes further into your fuel system with every mile driven. Driving on does your car far more harm than our van heading out to a difficult place, and that's no problem for us.

Driven it already? Pull in, and read this

The M23 is the road which counts here, and sits under 3 miles from Woodmansterne. A drop in power, a rough idle, smoke: those are the symptoms when they appear, instead of a neat stop — and a misfuelled diesel will often take you onto it and some way along before anything feels wrong at all.

The next safe junction is the one to take. Turn off there, then leave the restarting alone. Presume the worst of that on a long drive. Anything near the under 15 miles to the closest city, and the petrol has been through your filter, through the pump, through the injectors. Mention it when you ring. What we bring alters.

All about Woodmansterne

Woodmansterne is a small village in Surrey, situated inland at an elevation of 126 metres, approximately 12.8 miles from London. Woodmansterne has a mix of housing types, but semi-detached homes are predominant, and the village is close to nearby places such as Clock House and Little Woodcote. Woodmansterne remains a quiet residential community with a population of around 1043 people.

Our visit in Woodmansterne, step by step

  • Our engineers ask first, price after. What was put in? How much? Has your engine run? Those answers alter what the work really is.
  • The contaminated fuel comes out of the tank.
  • We rinse the lines and clear your filter, so what is left in the fuel system isn't what caused the issue.
  • Our technicians put clean diesel in and prime the system.
  • Our technicians fire it up and check it runs properly on new diesel.

From there, you are ready to drive away. There's no need for a workshop at any stage, since the work is all done where the vehicle is, and when it's noticed early, lasting damage is very uncommon.

AdBlue in the diesel tank by mistake, in Woodmansterne?

AdBlue instead of petrol? Then the opening instruction is unchanged — the engine remains off — whereas this problem under it is a distinct one altogether. The lubrication a fuel system relies on gets stripped away by petrol, which dilutes your diesel. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and build-up in its place.

Both are ours. There is a separate Woodmansterne page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two.

How much is a petrol-in-diesel fuel drain in Woodmansterne?

We can't put one figure on this page truthfully, because the job is not one job. What changes it:

  • Started? Driven? Either answer counts more than anything else on this list.
  • How much of the wrong fuel got in, set against how much your tank holds.
  • Whether it is unleaded or AdBlue.
  • Access: the vehicle's position, and if working on it there's sensible for a technician.

Tell us what your car is, how much got in, and whether your motor has run. A firm answer comes back, not a range. Car at home, going nowhere, nothing urgent about it — is fine for that.

Petrol in diesel queries from Woodmansterne motorists

Fuel drains on a Woodmansterne petrol station forecourt

Plenty of what our technicians do happens nowhere else. So yes. Tell us which one you are at when you phone and we'll tell you whether we can work there. With the site's permission we work at BP and the other forecourts nearby regularly.

How much petrol is too much for a diesel?

Litres aren't the yardstick. Ratio is, and a lot more than either, it matters whether anything has been run. Five litres in an almost empty tank is a different case from five in a full one — but either way, the thing that determines how much work is required is if that mixture has been sucked through your fuel system.

I put petrol in my diesel and drove it. What now?

Somewhere safe, then stop, then switch off and keep it off. It is recoverable much more frequently than people fear, even though driving is what moves the trouble from that tank into your pump and injectors — and the single most helpful thing you can do now is not restart it.

My warranty — does a fuel drain void it?

No. Carried out properly, clearing and purging is no modification at all, and the warranty from your manufacturer is unaffected by it. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

Could I put some two-stroke in and just drive?

No. It belongs to a distinct fault from a bygone era, and petrol has thinned something no oil of that kind replaces. That tank still has petrol in it after that, and your pump still has to live with it.

Does petrol in a diesel have to go to a main dealer?

Wherever the car is, our technicians drain and clean it there, so a visit to the main dealer doesn't come into it.

Waiting next to it?

Keep the car turned off.

If you have already driven the vehicle, stop somewhere safe, switch it off then keep it off. This is recoverable from a lot more commonly than motorists assume, and a still, cold motor is the best place to be in.
