In my defence, I'd worked non-stop the over the weekend, literally 24/7, so I wasn't as mentally sharp as I should've been.

it will be ok as you stopped the engine, its when people drive until the engine stops on its own that the real damage gets done, high pressure pump/injectors

I don't know how sensitive the injectors are on your Defender, but I once miss-fuelled a Mercedes ML270cdi. Drove about 10 miles which was about long enough for the fuel to have reached the engine. Lost power then stopped. Having bled the system and flushed fuel with additives through I was warned that the injectors may be damaged. Less than 1000 miles later it needed 5 new injectors

If run with petrol in for a reasonable amount of time the high pressure pump will wear rapidly due to the lack of lubricity in petrol (the pump runs something like 1500 bar)
I have put a small amount of petrol in a diesel car before but not started the engine before i realised so put a load of diesel in to dilute the petrol, the car did,nt run quite as normal until that fuel was used up but it had no long term effects. Hope it turns out o.k for you  2005 Td5 90 XS

Depends how you did those 3 miles that you drove.... If it was a gentle drive at part-load, chances are you will get away with it completely. If you "put your foot down" for those three miles, then you could have done a bit of damage, but that isn't going to show for a while. If you do need a new injector or four in the future, you'll know why! The CR pump should be quite robust against this for a few miles, even at 75% gasoline, so not much to concern yourself there. Roads? Where we're going, we don't need roads.

I drove through central High Wycombe, so stop-start traffic and little side streets.
When I first heard the motor having problems I stepped on the accelerator a few times, typical man response. Tried to drive off and saw there was no power, really struggling so I pulled over for good. We'll see - time will tell! |

Dropped the iPhone, had to make an appointment to exchange it for a new one for 200+ euro. Got it, went home and it was a faulty one. Made a new appointment and the phone strangely worked. The Apple "genius" handed the phone back to me and 3 hours later the bloody phone died again. Completely irritated, I made the third appointment when I got home and end of the week I was on my way to Amsterdam again. Fuel warning 'dingdong' made me decide to fill her up at the nearest station so I wouldn't come to a halt half way to the store.
Drove off and realised the fuel bill was a bit high. Couldn't be right, so after about 300 meters I immediately steered the car in the grass and switched off the engine. Needless to say I missed my appointment. 
I must admit, dealer service was superb when I called them, but all in all a very expensive two weeks as i had payed for the exchange of a new phone, 3 times 50 euro for fueling and parking costs every time I reached Amsterdam, and a hefty invoice for draining, cleaning and refuelling of the Defender. Lesson learned  never drop you phone! |

I put unleaded into my Merc e class CD320 about 10 years ago (when BP first brought out their Ultimate Diesel with the similar coloured pumps as unleaded..
 ).
I drove about 5 miles before it started to run rough. It was collected by the local (Reading) Merc dealer who said that the high pressure fuel pump was likely to have run dry (the diesel is the lubricant) and will have sent fine metal particles into the injectors and cylinders. A significant amount of the engine and fuel system was changed at a cost of approx £5k. The cost was covered by my company/leasing company apart from a major source of embarrassment - and 10 years of fear of doing it again. Good luck with yours, would be interested to know how the TDCi engine stands up to unleaded. Cheers Simon |

 - make sure you have a decent case for your new I phone - daughter dropped hers & I ended up fitting a new front - very easy although a challenge with man hands 2020 P300 HSE |

i did it once, filled a diesel Pug up with petrol ... drove about 10 miles, thought something was wrong, stopped, recovered, flushed and no issues what so ever

My wife once did the same with a Renault Laguna company car. She got about 10 miles before it died. Had the tank drained and system flushed and all was well, with no obvious ill effects. Darren

I did it once, about 7 years ago, realised after id put about 5l in the tank , topped off with diesel, never even noticed it was in there. It is a 200Tdi though and they're bullet proof! (that'll be me replacing the engine in about 2 days then when it goes bang!)

The Bosch rotary pumps on the 200 and 300Tdi are pretty good for most abuse, although they do not like being overspeeded at the same time as misfueled. Putting a little gasoline with a full tank of diesel fuel is an old-school trick to clean the engine up (cheaper than injector cleaner) and improve starting on cranky old motors in the winter. I wouldn't go out of my way to add gasoline in any proportion these days, partly because of the tighter tolerances in the CR high pressure pumps and injectors (hence tighter cleanliness spec's on fuel filtration) but partly because gasoline these days is an appalling mixture of fluids that makes even a petrol engine a wonder of chemical containment.
A drive through High Wycombe centre is unlikely to have caused much damage, maybe driving out towards Oxford might have strained things a bit! The trick with a misfueled CR diesel pump is to keep the engine speed and load down to the minimum (idle speed) where the rail setpoint pressure is lowest (for noise emissions) and the pump loads are minimised. Incidentally, don't bother trying for warranty on your CR pump if it fails in the future; the first thing that the manufacturers check is for misfueling, and they can tell straightaway by looking at the bearing surfaces!! Roads? Where we're going, we don't need roads. |

Might find this interesting Land Rover Defenders. 67 years heritage, minimal appearance changes, still going strong all over the world. Not a fashion vehicle, but fashionable to own. Made for the needy, not the greedy. Ta ta Defender
