First thing is first..... assume the possition in fron of him:
How much has he put in? The tank will need draining and the system flushed through there is the possibility of damaged parts too, but that will be dependant on how much petrol to diesel there is in the tank. Call the AA/ RAC, they will tow him to the nearest place that can do the work. It will cost about £200-500 to have the tank drained and the system flushed. Glyn   |

Drain the entire fuel system I'd have thought or at a minimum back to the fuel filter at the very least. Other that that very expensive! $W33T $0U7H3RN $UG4R

I did it once in France, in my defence I was knackered and probably shouldn't have been anywhere near machinery!
Anyway, petrol into a diesel is OK (even if you've been driving it) once the system has been flushed and new filters in. Diesel in a petrol is not so fine, even less so if you have driven it. Not sure about the AA but there are a few specialist firms out there that will come and flush your system on the spot. Nick 2.2 110 Tipper |

Ehhh, not to step on anyone's knowledge, but petrol would act as a solvent in a diesel car, and is extremely bad.
Diesel in a petrol (even if you managed to egt the wider nozzle into the tank) is still bad, but as you are essentially adding unwanted lubricants, you will get smoky exhaust, and bunged up filters. Either way, need draining & flushing. 2001 TD5 110 DCPU in Bonatti Grey |

Hopefully it has not seized the diesel pump which with putting petrol in to a diesel car can be bloody costly if not caught early enough!

A few years ago, my wife filled her company diesel Renault Laguna with petrol and it got about 12 miles before lurching to a stop. A couple of hundred pounds later and the tank had been sucked dry, re-filled with derv and off she went. No ill effects to the car, but endless embarrassment for my wife

petrol in a diesel will goose the fuel pump as a minimum, these are high pressure and rely on diesel as lubrication. Diesel in a petrol is not too bad, and is usually ok with tank drain, pipe blow through and filter changes and get away without damage.

Diesel in a Petrol wrecks the oxygen sensors in the exhaust.
A friend filled his Honda V-Tec years ago from the unleaded pump at his regular garage, he managed to drive 5 miles to the dealer but needed a new cat and sensors plus the drain. When he challenged the garage they informed him it MUST have been his mistake, half an hour later he got an appologetic phonecall, the garage owner had just filled his Jag from the same pump and couln't get off the fourcourt. The delivery driver put fuel in the wrong tanks
Had a couple of folks at my last job fill up the pool car with petrol, indeed I was the passenger on one of the occasions, I was half asleep as it was an early start so didnt take note, when the car started juddering and  started sweating and swearing I thought it a good idea to bite my tongue, never let him live it down since though |

Fair bit then. The less the better. I've always been used to buying nothing but diesel and always check but for those of you that have that have vehicles that are petrol and diesel I can see how it could easily be done! $W33T $0U7H3RN $UG4R

Luckily you can make that mistake only "unidirectional", meaning petrol into diesel.... A diesel filling spout will not fit into a petrol filling opening as they made it on purpose much thicker. So you will get stuck before the diesel spout could open the petrol tank valve which makes it quite unlikely not to notice something is wrong. You never actually own a Defender. You merely look after it for the next generation.

There will be a variety of stories because a lot will depend on filling habits.
If you fill up once you hit 3/4 tank and you accidentally add 15 litres of petrol to 60 litres of Diesel you shouldn't have much problems because it is a 2:1 ratio But if you are someone who likes to empty the tank before filling then put £100 petrol in you are going to break something at it is straight petrol going through the system. I have known many people who have made this mistake (my dad twice when he had a bike and my mum had a diesel). Both occasions it cost £200 for the work, £60 lost in fuel (when they drain the tank it goes straight into waste tanks, and then £60 for another full tank of fuel. That is only because my mum keeps a minimum of half a tank (has to do a 40 mile commute across a remote hill route). Glyn |
