Petrol in Diesel

Petrol in a Diesel Car in Port Solent

If you have not started the engine as yet, don't. A fuel drain and nothing else is nearly always what a motor needs while the fuel is still in that tank and the engine has not yet turned over, which is why it is the next few minutes that matter, not how much got in. Petrol in Diesel travels to the car wherever it has stopped in Port Solent or the rest of Hampshire, on the forecourt, at the roadside or on a drive, and drains and cleans it there. Call us before anything else happens, so you'll see what comes from there.

What to do now about petrol in a diesel

  • Whenever you drive, the pump and the injectors wear down. That is why you do not crank it, and why you never believe it once it has started. The catch about petrol in a diesel specifically — the point people get wrong — is that it pulls away normally for the first mile or two. Diesel in a petrol engine generally won't run at all, which stops the person and stops the wear with them. This one lets you carry on.
  • Diesel burns, and before it ignites it protects — the injection pump, its injectors. Petrol handles only the burning. So leave the ignition alone too: switching it on is usually sufficient to prime that system, and priming moves petrol from that tank into exactly those parts.
  • Don't add diesel on top to dilute it. A diesel fuel system will not handle petrol by percentage as that guidance implies, and topping up gets rid of nothing — it only gives you a fuller tank of the same blend. The type makes no difference either: super unleaded is simply petrol.
  • Stay put if it's sensible to. Hazards on, motor off, keep the car. Wherever you have stopped — the verge on Port Way, anywhere — an awkward location for us trumps a started engine, and nothing is quicker for us to sort out than a car that never moved.
  • Get your position ready before you call. A postcode starting PO6 4 and whatever is nearest to you with a sign on it is the difference between our van arriving and a van circling.
  • Ring 0333 366 0103. Tell us what got in, roughly how much, and whether the car has run. Those three facts settle the whole job.

Petrol in a diesel Volkswagen Golf, left at Portchester since this morning? The day has cost you nothing — fuel sitting in a tank is inert. It was the journey in that pulled weakened diesel through your pump. Call us before you move the car.

Petrol in your Ford Focus, and it takes diesel? Shopping in your boot, you at Aldi, somewhere in Port Solent? Then phone us, and leave the motor out of it — not even to exit the space. Someone comes out to you. Tank cleared, fuel lines flushed, clean diesel in, and home you go. Gentle throttle over a mile draws very little, so these are usually the simple cases.

Nothing warns you, since from the driver's seat there's nothing to be warned about. The diesel Audi A3 will have felt entirely usual on the way back from St Paul's Catholic Primary School, and they all do — which is the snag with petrol in a diesel and not the reverse. Diesel in a petrol car mostly refuses to run, stopping the driver and stopping the harm with them. Petrol in a diesel starts, ticks over, drives off as though nothing had happened, and all the while your pump keeps working without the lubrication its fuel is meant to supply. Tell us approximately how far, and how hard. The harder counts more.

Nothing gets worse while it sits. Whatever the diesel Vauxhall Insignia did on the way to Horsea Island Country Park, it is doing none of it now: your pump is not turning. So take your time — but don't drive it home to buy yourself any.

Someone sure of themselves will tell you to drain the vehicle then put fresh diesel in. Half right, that. Try it on a diesel Renault Captur close to The Boardwalk Shopping Centre and the motor will start — which is precisely why it sounds like sense. Here's the trouble: there's petrol left in your filter and the feed lines, and the first thing the engine does is suck it back through the pump again. Emptying a tank achieves nothing about fuel that already left that tank. Call us. Your system gets rinsed, the filter comes off where there's one worth removing, and that is what separates a fixed motor from one that simply starts.

Forecourt draining for petrol in a diesel

It begins at a pump, mostly. Regularly the work finishes on site as well. The drain usually takes place there and then. Still on the forecourt at Tesco? Given the site's permission, that's a spot our engineers work, and often.

Nowhere else except the forecourt can this be stopped with the engine still unstarted. Our engineers can still sort it out where it stands, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been fired up and driven there, and that pulled fuel through your filter and into the high-pressure fuel pump, all the way from your tank. None of that is a calamity, although the flush then has to reach past the tank to the lines and the fuel filter, and the few seconds between seeing your receipt and reaching for the key are what decide that.

The staff will usually help you move the vehicle out from the pump so the next motorist can get by. That's worth doing. Moving the car four lengths doesn't justify starting the engine.

Parts our team reach around Port Solent

Those same trips carry us to Paulsgrove, Portchester, Wymering, Highbury and Vicarage Row as well as Port Solent, which is a coastal area.

We do come. Those places above are just the nearest neighbours, and a page exists for most towns in Hampshire, so an absence from the list isn't an absence from the coverage. Close to a border, or anywhere the satnav misreads? Contact us to ask instead of presuming.

The area the page covers sits on our map. Our technicians work by the road, at forecourts, on driveways and in car parks throughout all of it, and your vehicle does not need to come to us.

Port Solent: stuck where you stopped

Not everyone finds a sensible place to stop. If you noticed after setting off and landed along the verge of Carbis Close, or in a lay-by somewhere with the hazard lights on, that's a routine call for us rather than an unusual one.

Whether you wait with your car or keep clear of it hangs on whether sitting in it feels sensible. Don't fire it up to reach a safer place. It'll go — a diesel on petrol normally obliges — and each mile of obliging draws that blend deeper into the system. However awkward the spot, it's no problem for us to get to it, and that is a lot better for the vehicle than carrying on.

Driven it already? Pull over, and check this

under a mile out of Port Solent, the local M27 is what matters here. It will frequently take you onto it, and some way along, before you feel a thing. Then it's smoke, a rough idle and power draining away — not a neat stop. Misfilled diesels rarely give you one of those.

The first safe junction is the one to take. Switch off there, then leave the restarting alone. On a longer drive — anything close to the under 5 miles to the closest city — assume the contamination has been through the filter, the pump and the injectors, and say so when you call. It changes what our technicians bring.

Where's Port Solent?

Port Solent is a coastal locality in Hampshire, situated near the city of Portsmouth and overlooking the Solent Strait. Port Solent sits at a low elevation of around 2 metres, with its terraced housing stock reflecting its relatively recent development as a residential area. Port Solent is close to other nearby places such as Paulsgrove, Portchester, and Wymering, and is within easy reach of Portsmouth's amenities.

When our engineers arrive with you in Port Solent: what we do

  • The answers shape the work, which is why our technicians ask before quoting: what was put in, how much of it, and whether the engine has run.
  • The contaminated mixture is pulled from your tank.
  • What is left in the fuel system shouldn't be what created the problem, and so your fuel lines get rinsed and your filter cleared.
  • New diesel goes in, and then the system gets bled.
  • After it's fired up, our engineers make sure it runs correctly on fresh diesel.

From that point, you're ready to drive away. Everything is done where your car is, so it never has to be taken to a workshop, and when it has been spotted soon, long-term damage is very uncommon.

Port Solent AdBlue removal is a different problem

If what went in was AdBlue rather than petrol, the first step is unchanged — do not crank it — but this fault is not. Petrol does two things to diesel: dilutes it, and removes the protection the system relies on. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get corrosion instead, plus build-up.

AdBlue removal around Port Solent has a page of its own with the full story on it, including why it is usually the more significant of the two. We deal with both.

Port Solent costs for a petrol-in-diesel drain

Honestly, no single price belongs on a page like this. This job differs. Here's what moves it:

  • Started? Driven? Either answer counts more than anything else on this list.
  • How much of the wrong fuel went in, set against how much your tank can hold.
  • Whether it is unleaded or AdBlue.
  • Whether a van can sensibly reach your vehicle and work on it, which rests on where your vehicle is.

The car, the quantity, whether it has run — give us those and the answer comes back straight instead of as a range. For the vehicle at home that's going nowhere and is not time-critical, works too.

Petrol in diesel: frequent queries around Port Solent

Fuel drains on a Port Solent petrol station forecourt

Yes, and it's where a good share of this work gets done. Tell us which one you are at when you phone and we'll tell you if we can work there. With the station's permission we visit Esso and the other forecourts locally routinely.

How much petrol in a diesel is too much?

Whether your engine has run matters far more, though the ratio matters too, instead of the litres. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that mix been sucked right through, or has it not?

Already driven it with petrol in your diesel? What now?

Somewhere safe, then stop, then turn off and keep it off. Driving is what shifts the problem from the tank into the pump and injectors — but it's salvageable much more commonly than motorists expect, and the single most helpful thing you can do now is not restart the car.

Will a fuel drain void my warranty?

A manufacturer's warranty survives a drain and flush done to a good standard, which is no alteration at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

Adding two-stroke oil, then driving home

No. Two-stroke oil is an old workaround for a distinct problem and it does not restore what petrol has diluted. Petrol stays in that tank after that, whatever else goes in, and your pump gets no break from it.

Do I need a main dealer for petrol in a diesel?

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

Still with the vehicle?

Keep the car shut off.

Driven it already? Then somewhere sensible, stop, turn off, and no restarting the vehicle later. This is recoverable from much more often than motorists assume, and a parked, cold vehicle is the best place to be in.

Throughout Hampshire and in Port Solent: call-out fuel draining, at home or on the forecourt or at the kerbside.
