Petrol in Diesel

Put Petrol in a Diesel Car in Mudd? Don't Start It

Petrol in Diesel drains and cleans wrong-fuelled cars where they stand, on the forecourt, at the roadside or on a drive, across Mudd and the rest of Greater Manchester. The very first thing to do is not to fire up your engine. When the engine has not run and the petrol is still sitting in that tank, a drain is almost always all it requires, and the following few minutes decide that, not how much got in. Call us and then we can explain what happens from here before you do anything else.

Petrol in a diesel: what to try now

  • Whenever you drive, your pump and the fuel injectors wear. That is why you don't start the car, and why you never trust it once it has started. The catch about petrol in a diesel in particular — the bit people get wrong — is that it drives off normally for the first mile or two. Diesel in a petrol engine typically can't run at all, which stops the motorist and stops the harm with them. This one lets you carry on.
  • Two jobs, diesel: it burns, and on the way through it keeps that high-pressure fuel pump and injectors lubricated. Petrol only manages the one. Which is why the car's ignition stays off too — turn it on and you often prime that system, and that is petrol exiting the tank for just those components.
  • Topping up takes out nothing. It hands you a bigger tank of the same blend, since a diesel fuel system will not cope with petrol by percentage the way that guidance implies — so do not add diesel on top to dilute it. Octane is immaterial too: super unleaded is petrol.
  • We would much rather travel to a tricky location than have it started — so if you reasonably can, stay still. Nothing is quicker to deal with than a vehicle that has not shifted. On the verge on Church Brow, that means hazards on and leave the vehicle.
  • Keep your whereabouts prepared before you ring. A postcode that starts SK14 6 and whatever is closest to you with a label on it is the difference between our van arriving and a van circling.
  • Three answers determine your whole visit: the liquid you put in, the rough volume involved, plus if anything has been going since. The line is 0333 366 0103.

Nothing about the time since has cost you anything. Fuel in a tank is dormant, and so a diesel Volkswagen Golf left outside Broadbottom this morning is no worse at five than it was at nine — what sucked thinned diesel through the pump was the trip in. Ring us before you set off to collect the car.

Petrol in your Renault Clio, and it takes diesel? Shopping in your boot, you at Tesco Extra, somewhere in Mudd? Then ring us, and leave your engine out of it — not even to get out of that bay. Someone comes out to you. Tank drained, fuel lines flushed, new diesel in, and home you go. Easy throttle over a mile draws hardly anything, so these are usually the straightforward jobs.

Nothing warns you, since from the driver's seat there is nothing to be warned about. The diesel Peugeot 308 will have felt perfectly normal on the way back from Mottram CofE Primary School, and they all do — which is the trap with petrol in a diesel instead of the reverse. Diesel in a petrol vehicle usually refuses to run, stopping the driver and stopping the damage with them. Petrol in a diesel starts, idles, pulls away as though nothing had happened, and all the while the pump keeps working without the lubrication its fuel is supposed to supply. Tell us roughly how far, and how hard. The harder counts more.

Nothing gets worse while it waits. Whatever the diesel Audi A6 did on the way to Great Wood, it is doing none of it now: the pump isn't turning. So take your time — but never drive the vehicle home to buy yourself any.

That deadness is the fuel failing to build pressure properly, not the motor giving up — and with no warning for it, motors in that position typically get driven again before anybody calls. Do not. A couple of streets is all it got: throttle gone dead, idle turned lumpy, and a diesel Kia Sportage now sitting close to Statue of L.S. Lowry. Switch the vehicle off and call us.

Forecourt draining for petrol in a diesel

The job starts at a forecourt, typically. Quite often the job ends there as well. We operate on station forecourts all the time, with the owner's consent, so if you're still at Shell that is generally where the drain takes place.

Nowhere other than a forecourt can the mistake be caught with the engine still unstarted. Everywhere else — a car park, a private drive, a lay-by — the car was switched on and driven to get there, which means fuel was drawn from that tank, through the fuel filter and into the high-pressure pump. That is not a catastrophe, and we can still sort it out where it is. It does mean your lines and your filter need rinsing as well as that tank, and that's settled by the few seconds between checking your receipt and going for the keys.

Wheel the car out of the way if the staff offer, and they normally will. The next motorist gets by the petrol pump, and that is worth doing. Starting it over four vehicle lengths? No.

Can our engineers serve your corner of Mudd?

As a residential suburb, Mudd gets a steady call, while the villages round about go with it on that same round: Mottram in Longdendale and Warhill, The Hague and Hillend, Spout Green.

Not on that list? That means nothing. The places above are just the nearest few, and the majority of places across Greater Manchester have a page of their own somewhere on the site. Ring us to enquire rather than assuming, above all if you're on the boundary or anywhere your phone misreads.

The ground this page covers sits on this map. The car doesn't need to come to us. Our technicians work over every bit of it — roadside, forecourts, driveways, car parks.

Stuck on the kerbside near Mudd

Not everybody gets the chance to pull over anywhere suitable. Hazards on at a lay-by somewhere, or stopped on the verge on Dale View because you worked it out after setting off — our technicians take that call so often that it is the usual kind.

Clear of your car when it is not safe to be there, by it if it is. Don't restart the motor to limp the car somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mixture further into your fuel system. Driving on causes your car far more harm than a technician coming out to a tricky location, and that's no trouble for us.

Petrol in a diesel, but the vehicle has gone

This is where the M67 comes in, under a mile from Mudd. Some way along, and onto it in the first place: a wrongly fuelled diesel will usually do both before anything seems wrong. What you get then is rarely a neat stop. Power ebbs away, your idle goes lumpy, and there may be smoke.

Take the next junction that is sensible, pull up there, and do not restart it to move it. It affects what our engineers bring, and so mention it when you phone: on a longer run — anything close to the under 10 miles to the nearest city — assume the contamination has been through your filter, your pump and your injectors.

About Mudd

Mudd is a suburban area situated on the riverside in Greater Manchester, with a mix of terraced housing and a population of around 2401 residents. Mudd sits at an elevation of 232 metres, approximately 9.8 miles from Manchester and 156.1 miles from London. Mudd is located near other local places such as Mottram in Longdendale and Warhill.

What we do when we arrive with you in Mudd

  • Our technicians find out what was put in, how much, and if the motor has run. The answers shape the work, which is why our technicians ask before pricing.
  • Out goes the contaminated mixture.
  • We purge the lines and clean your filter, and so what's left in the fuel system is not what created the problem.
  • Bleeding the system follows, once clean diesel is in.
  • It's run with new diesel in it, and we make sure that it's running correctly.

At that point it is ready to pull away. All of it is done where the vehicle is, so it never needs to go to a garage, and when it has been noticed soon, permanent damage is very rare.

AdBlue in your diesel tank by mistake, in Mudd?

If what went in was AdBlue rather than petrol, the first step is the same — never fire it up — but this fault is not. The protection a fuel system depends on gets stripped away by petrol, which weakens your diesel. Rust and build-up are what a diesel tank gets instead, as AdBlue is urea dissolved in water.

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

Mudd costs for a petrol-in-diesel fuel drain

Truthfully, no single figure belongs on a page like this. The job varies. Here's what moves it:

  • Has it been started or driven? Nothing else counts for as much.
  • How much of the wrong fuel went in, judged against how much that tank holds.
  • AdBlue or petrol, whichever went in.
  • Access: the car's position, and if working on it there is safe for our van.

Tell us what the car is, how much went in, and whether the engine has run. A firm answer comes back, not a range. Not urgent, with your car at home and going nowhere? Then works.

Petrol in diesel: frequent questions around Mudd

Fuel drains on a Mudd petrol station forecourt

A large portion of this work happens there, so yes. Regularly, provided the site agrees: BP, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that spot is something our engineers answer there and then.

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

Proportion settles it rather than litres — and more than either, whether the motor has run. Five litres in a nearly empty tank is a different matter from five in a full one — but either way, the thing that settles how much work is required is if that blend has been pulled through the system.

I put petrol in my diesel and drove the car. What next?

Switch off somewhere sensible, and keep it that way after you stop. Driving shifts the problem along — out of your tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you is not restarting the vehicle.

Is a fuel drain going to void my warranty?

A drain and flush carried out correctly isn't an alteration and doesn't invalidate a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

Can I just add two-stroke oil and drive home?

Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol weakened. No. The tank still has petrol in it later on, and the pump still has to cope with it.

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

You don't need one. Your car is drained and cleaned wherever it is, with no need to bring it to a dealership.

You, and your vehicle, still together?

Never turn your engine on again.

If you have already driven it, stop somewhere sensible, turn it off then keep it off. A parked, cold vehicle is the best place to be in, and this is recoverable from far more regularly than motorists assume.

Throughout Greater Manchester and around Mudd: on-site fuel draining, at home or on the forecourt or at the roadside.
