A friend of mine did it and the car ran better afterwards, just drained and cleaned out, new filters, no problem.
There was also a similar debate on TruckNet about the same and the general consensus between the older drivers was that a bit of petrol in the tank would be done as a matter of course during cold spells to raise the freezing point of the fuel carried.
Admittedly both these examples relate to older engines.

A bit of P in the D engine 30 years ago was considered ok but in these highly strung tight tolerance diesel engines it strips the lubricant in seconds
Thats something people need to bear in mind......DrLex, seeing as you seem to be grammatically bent, is this correct?

I've been privy to a couple of gallons of OMD80 going into the bowels of several vehicles after a misfuel,
It has the effect of turning the contents into 2 stroke ?
Some of the vehicles have gone on to cover thousands of miles after and none of the ones I have been witness to have ever packed up,
I suppose this method negates the need for environmental waste after the clean up.
I've told several people about this and none of them believe it's possible ! funny reallyOnly dead fish go with the Flow !

Everyone i have seen that has stopped running after misfueling has totally wrecked the hp fuel pumps. The swarf from this fills the injector rails,pipes and injectors which is the main reason they cant just be chucked back together. If you fit a new hp pump without replacing the fuel lines the whole problems starts again.
As stated in previous posts this could be one reason why we are seeing a few engine failures now,especially bigends!!

for you mate!
I guess you are currently living up to your forum name...........
My wife did it 12 months ago in her Astra - fortunately she didn't even put the key in the ignition before she realised, I managed to tow it home and drain the petrol out of the tank myself and all was well, the petrol is still in a can and happily running my lawn mower. She couldn't understand why I wasn't cross.......... easy mistake to make IMHO. So unlucky that your wife didn't notice.....

Friend did it in a brand new Audi A4 coiple of weeks ago and also drove the car to a grinding stop. He rang Audi assistance and they sent the AA out to drai the fuel and bleed the fuel line through, a bit like the post above. Refilled with tank of diesel and told to drive 200 miles then refill again. He did all of this and has had no issues, Audi have even told him his warranty is not at risk and if there is engine issues later it wil still be covered MY17 D5 1st Edition Namib Orange

Very different with LR im affraid. Depending on what youve done depends on the level of repair required. If its at a LR garage and you dont do what is needed then warranty restrictions will be placed on a future engine warranty request.

Guy at work did it last year, engine stopped. Towed to garage, drained fuel, fuel & engine oil change and 25k miles later still no issues.
I personally think if the car stops as a result of meat petrol then it will do less damage than if it keeps going on a heavily contaminated mix. With pure petrol the fuel will be through the pipes/pump and the engine will stop before it has the chance to run too long and suffer lubrication problems.
But that's just a opinion.

It happened in my wife's car last week (Mazda 3 Sport) with 2.0 l engine. This has the modern common rail injection system and it was driven for a few miles home and was spluttering a bit by the time she got here. It was recovered to the dealer's. They drained the tank, flushed the injection system fitted new filter (all for £120). We've just given it a sound thrashing for 700 miles to Grimsby and back with motorway all the way so at maximum speed. The engine's running as sweet as a nut - it's used no oil and there are no funny noises from under the bonnet..
If a new engine is to be at your expense, I'd follow some of the advice above about the injection system and give it a go with you existing engine.

I don't think anyone on here doubts that 'doing the minimum' in this situation will get you a car that will happily run for at least a year and probably more.
I think from the number and nature of 'unexplained' engine failures for 2nd or 3rd hand cars at relatively low milage hints that LR know what they are doing when they recommend such drastic repairs post a mis-fuel and that not all owners carry this out before moving the car on.Land Rover - Turning Drivers into Mechanics Since 1948

I totally agree that it is a diffrent beast all together and do not doubt that it is the correct way to go. But if the car is out of warranty and said person does not have funds for all that work perhaps there is a diffrent way to proceed.
However a couple of things to think about first, who makes the injector system in the LR? Is it the same people as in other cars ie Bosch etc. If so then surley all modern cars/makes with the same diesel injector manufacturer should suffer the same issues, but they do not, why?
If it is as said, petrol damages seals etc which causes wear and metal swarf to go forward to injectors, then surley replacing HP fuel system and injectors, replacing fuel and filter and an engine oil change, this should prevent further damage. If metal particles are small enough to get through the new injector then they are that small as to not do any serious damage and should be picked up within the oil filter. To be extra sure regular oil filter and oil change over the next 5000 miles should also help to prevent damage to major engine components.

No need to duck Russell.
I have lost count of the misfuels i have seen, it is a very common occurence. If the engine has been ran until it stops then damage will have been done, the petrol removes all lubrication properties within the hp fuel pump and damage can occur in minutes. Ive seen many a car where the vehicle has been recovered to another garage they have done a hp pump and a few injectors but have neglected to do the injection pipes.......fine particles still in there...goodbye new injectors. It greatly depends on what youve actually done to whether you can potentially get away with it.
If it were my car and yes if i wasnt in the know i probably would be inclined to do as little as i could get away with but like i said it will either bite you on the or you will be passing on alot of heartache to the next owner.
TLO seems to be advising similar ,would like to hear his take on this.
