Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Hedge End?

If you have not started the engine yet, don't. A fuel drain and nothing more is almost always what a motor requires while the petrol is still inside the tank and your engine has not yet turned over, which is why it is the coming few minutes that count, not how much was put in. Petrol in Diesel travels to the vehicle wherever it has come to rest in Hedge End or the remainder of Hampshire, on the forecourt, by the roadside or on a private drive, and drains and flushes it there. Just one ring our way will be plenty: our team will explain what follows from here. Try that straight away.

What to do now about petrol in a diesel

  • As you drive, the pump and the fuel injectors suffer. This is why you never start the vehicle, and why you never believe it once it has started. The thing about petrol in a diesel in particular — the point people get wrong — is that it drives off normally for the first mile or two. Diesel in a petrol engine generally will not run at all, which stops the motorist and stops the damage with them. This one lets you carry on.
  • Turning the ignition on often primes that system, and priming is what carries petrol out of that tank and into the pump and injectors. Those are the parts diesel keeps greased on its way through, before it combusts. Petrol does the burning and none of the oiling. Leave the car's ignition off.
  • Don't put diesel on top to thin it. A diesel fuel system will not cope with petrol by percentage in the way that advice assumes, and topping up gets rid of nothing — it just leaves you a fuller tank of the same mix. The grade makes no difference either: super unleaded is simply petrol.
  • Stay still if it is safe to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Saint Johns Road, anywhere — a tricky place for us trumps a started engine, and nothing is simpler for us to sort out than a motor that never moved.
  • Get your location ready before you phone. A postcode that starts SO30 4 and whatever is closest to you with a name on it is the difference between a van showing up and a van circling.
  • What went in, roughly how many litres, and also whether the engine has run — the three facts shape the entire call-out. Dial 0333 366 0103 and tell us.

Quarter past eight, a fast fill-up on the way in, and you realise at about eleven — by that point your diesel Renault Clio has been left at the nearest station for three hours. Ring us then keep the car exactly where it sits. The run in is the thing that counts now, since diesel does two tasks on its way through the engine: it burns, and before it burns it lubricates that high-pressure fuel pump and those injectors. Petrol does the first and not the second. So those few miles were travelled with your pump working on a liquid that had given up a lot of the protection it is built around — which is why the thing our engineers ask is how far you went, not how long your vehicle has been standing.

The awkward part is the bay, not your fuel. Vehicles either side of you, a trolley shelter behind, and from time to time a height limit on the way in that settles whether our van can reach you at all — so when you phone from a car park like the one outside ALDI, say how much space there is about you and which way round your car is. Those our technicians attend frequently. Should there be no room to work alongside the diesel Audi A4, it gets moved with the motor off, and not out of pedantry over a couple of seconds of running: priming occurs at every start, more of that blend leaves your tank for the pump, and two shunts into a better space have gradually made a worse job of what was just a vehicle sitting still.

Here is what a job in the car park outside The Barleycorn usually looks like. We arrive at your car, ask what got in, about how much, and whether your engine has run since — those three answers decide much of the work. Then the polluted mixture comes out of that tank, the fuel lines get rinsed, and the filter comes off where your Vauxhall Astra has a serviceable one. New diesel goes in and your system is primed. Then we start the car, confirm it runs correctly, and you set off.

Nothing gets worse whilst it waits. Whatever the diesel BMW X1 did on the way to Greta Park, it's doing none of it now: the pump isn't turning. So take your time — but do not drive it home to buy yourself any.

Why we're firm about not driving on: your pump rests before the injectors, and so whatever a worn-out pump gives off travels downstream with your fuel. Leave the Peugeot 208 by Barclays Bank Clock Plaque then ring us.

Mobile fuel drain van at a diesel car in Hedge End

On a forecourt: removing petrol from the diesel

Plenty of this job starts at the pump, so a fair portion of it gets done at one. The drain usually gets done on the spot. Still on the forecourt at Sainsbury's? Given the station's consent, that's a place our engineers work, and regularly.

At a forecourt, this gets stopped with the motor never started, and nowhere else does that. Fuel drawn out of that tank and through your filter, right to the high-pressure pump, is what occurs when the motor is switched on and your car is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush takes in the filter and the lines as well as your tank. That's still not a catastrophe, and our engineers deal with it where the car is. What determines it is whether the key was reached for in the seconds after the receipt was checked.

The staff will generally offer to push the car out from the pump so the next customer can get by. That is worth doing. Four vehicle lengths is not worth the risk.

Can we reach your corner of Hedge End?

Those same runs take us to Wildern, Shamblehurst, Netley Hill, Thornhill Park and Dowds Farm as well as Hedge End, which is a riverside town.

Not on that list? It tells you nothing. The names above are just the closest few, and nearly all locations in Hampshire have a page of their own somewhere on the site. Close to the border, or somewhere your satnav misreads? Ring us and ask rather than guessing.

Use our map for the ground shown on this page. Your vehicle doesn't need to come to us. Our technicians work over the lot — roadside, forecourts, driveways, car parks.

Hedge End: stuck wherever you pulled up

Some drivers have no suitable spot to pull in whatsoever. A routine call for us rather than an odd one: realised after setting off, landed by the verge on Wildern Lane or in a lay-by with the hazards going.

Remain with the motor when it is sensible to wait there, and out of it if it isn't. Never fire up the engine to nurse the car somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mixture further into the system. We'll take the van to an awkward place without any trouble, and for your car that is far better than carrying on.

Run it already? Pull over, and check this

under a mile out of Hedge End, your M27 is what counts now. It will usually get you onto it, and some way along, before you feel a thing. Then it is smoke, a lumpy idle and power draining away — not a neat stop. Wrongly fuelled diesels rarely give you one of those.

Come off at the first sensible junction, switch off, and do not restart the vehicle to reposition. Assume the worst of that on a long trip. Anything close to the under 5 miles to the closest city, and the petrol has been through your filter, through the pump, through the injectors. Mention it when you call. What our technicians bring changes.

Hedge End itself

Hedge End is a town situated on the River Hamble in Hampshire, with a mix of residential and commercial areas. Hedge End has a population of around 18487 people and is characterized by predominantly detached housing. Hedge End is located near the cities of Southampton and Portsmouth, and is close to nearby places such as Wildern, Shamblehurst, and Netley Hill. Hedge End sits at an elevation of 31 metres above sea level, and is about 65 miles from London.

What our technicians do when we reach you around Hedge End

  • The responses alter the work, which is why we ask before quoting: what was put in, how much of that, and if the motor has run.
  • We clear your tank of the polluted mixture.
  • What is remaining in the system should not be what started the problem, so your fuel lines get purged and the filter cleared.
  • We put new diesel in and prime your system.
  • Your engine is started and checked to be sure it runs correctly on clean diesel.

From there, you are ready to pull away. There's no need for a workshop at any point, as the work is all done where your car is, and when it is noticed soon, long-term damage is very unusual.

AdBlue in your diesel tank by mistake, in Hedge End?

AdBlue rather than petrol? Then the opening step is unchanged — the engine remains off — while the issue underneath it's a separate one altogether. Weakened diesel, and no protection left for the fuel system that relies on it. That's petrol. Corrosion and residue are what a diesel tank gets instead, as AdBlue is urea dissolved in water.

Often the more serious of the two, AdBlue — and the details lives on its own Hedge End page. Both are ours to handle.

What a petrol-in-diesel fuel drain costs in Hedge End

One number would not be fair here, because this is not one job. These are the things that change it:

  • This is the main one: whether your engine has been run, or driven.
  • How much of the wrong fuel went in, compared with how much your tank holds.
  • AdBlue or petrol, whichever was put in.
  • Where is it? And can our van reach it and work there sensibly?

A firm answer instead of a range is what you get for telling us three things: your vehicle, the quantity, and if it has run. For the car at home that is going nowhere and isn't pressing, works too.

Hedge End drivers ask us these about petrol in diesel

Fuel drains on a Hedge End petrol station forecourt

Yes, and it is where a big part of this work happens. Regularly, provided the site consents: Texaco, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that spot is something our technicians answer straight away.

A couple of litres of petrol in a diesel — too much?

It hinges on the proportion instead of the litres, and much more on whether your engine has run. What decides how much work is needed is whether that mix has been pulled through your fuel system — because although five litres in a nearly empty tank is a distinct case from five in a full one, either way that is the query.

I drove the vehicle after putting petrol in my diesel. What next?

Somewhere safe, then stop, then switch off and leave it off. Driving is what takes the problem from the tank into the pump and injectors — but it's fixable a lot more frequently than people fear, and the single most useful thing you can do now is not restart it.

Is a fuel drain going to void my warranty?

No. Carried out correctly, draining and flushing is no modification at all, and the warranty from your manufacturer is unaffected by it. What is likelier to start an argument is a diesel that has been run on petrol. One more reason for your engine to stay off.

Two-stroke oil in the tank, and then home?

No. It belongs to a different problem from a different era, and petrol has diluted something no oil of that kind puts back. Later? Still petrol in the tank, and a pump that has to live with the stuff.

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

Not at all. Our technicians drain and flush the vehicle wherever it is, so there's no need to bring it to a dealership.

Still with the vehicle?

That engine remains off.

Turn it off somewhere safe then keep it off, if you have already driven it. A stationary, cold motor is the best position to be in, and this is recoverable from a lot more regularly than motorists fear.

Throughout Hampshire and in Hedge End: on-site fuel draining, at home or on the forecourt or at the roadside.
