Someone needs to drive until it runs out. I've gone below the red and not run out.

I guess it would b stupid to assume empty would indicated by the needle being in same position as when ignition is off off ?

On the 2.2 you will at some point get the low fuel PCM induced surging before it does run out. Not sure how long this will last before the engine stops but ive been very close.

Yep, done that a couple of times too. Not sure how much is left. 35 miles has been the limit of my nerve thus far once the fuel light has come on.

I might not be the right person to ask mate, but I actually love the 2.4 AND the 2.2 In fact I don't think there is a Land Rover Defender ever produced which I somehow don't love like crazy. If you have children you will know what I mean. They drive you absolutely nuts and you want to kill them most of the time, but you never stop loving them anyway! Each kid figures out their own very unique and special way of convincing you to tear your own hair out. Well, Defenders are exactly like that! In my view, and in a nutshell, the more of a blank canvas the Defender, the more attractive the product. The standard 2.4 models, without mods, were all fairly decent utilities, no serious complaints, they are very practical, not exhilarating but adequately powered and will likely turn out to last longer than those newer 2.2 models which include the technology of introducing fuel into the engine during the exhaust cycle. Just think about how ridiculous that actually is. We have found that this technology has absolutely destroyed any hopes of ensuring efficient oil management in the long term and the contamination of the crankshaft oils by this process is, in my view, going to become a fatal flaw of the 2.2 as time progresses. If you can get a 2.2 without these dumb "improvements", like the "military specs" for example, I would choose the 2.2 above the latest 2.4 any day of the week. If I was offered the 2.2 new vs a good 2.4, and, if forced to comply with present MoT legislation, I would even pay more for the 2.4 and might reject the 2.2 entirely out of hand. If the 2.2 had none of the kak EU compliance stuff, well the 2.2 would probably be my choice. But that is just me, and trust me, I am no typical Defender owner so please don't let my views influence you too much! Everyone will probably disagree with me on this one, but we can raise this topic again in 5 years time. ****CENSORED**** |

It is an odd feeling when it happens as you know
 , im also scared to take it further as it may not do the electronic pump tank any good to run dry. |

Got to keep that Nato 5l jerry can handy Pete, and remember, only 4l of that fuel will be used for propulsion, the rest is used to drive the DPF!  ****CENSORED**** |

+1 from what we have all seen and read of it so far and the problems raised already with cars, oils and dpf lights in its low age of a 2 or 3 year production life its had. We should date this page and look back as you say in a few years time on how many cars are still running without any crankshafts barings knocking the heads of due to them being warn from diesel contaminates oils that were changed exactley as per the LR service recomendations and or following the MIL light that comes on at 7% contaminated. May be I should change the 7% warning light at remap time to give people a early warning system to change their oil and prolong engine life by servicing it more regular than LR state is good. Pete |

No kidding Pete! Listen, with Amsoil, Mobil 1 and another brand I prefer not to mention, we achieved amazing results from all our diesel motors. Simple common sense management and you would be amazed at the life expectancy of almost any diesel engine. The 2.2 ? Mobil has lost a Motza paying out on guarantees to us even though we all know the problem has nothing to do with their product. Given the diesel contaminants we regularly find in only 3000 miles use of a 2.2 with EGR I am willing to guarantee that Land Rover is in for some pretty nasty claims not too long from now. Does anyone have any idea how destructive a diesel contaminated crank is for a high performance motor like the 2.2? Not only that, but there is literally NO OIL in all of creation which can function with the high levels of diesel contamination we are experiencing in these new motors. You could ask all the angels in heaven to descend to the Mobil R&D offices to produce the perfect oil and you would still be effed many thousands of miles before the 20k recommended by LR. ****CENSORED**** |

Look on the bright side my wife has a Mazda CX5... perfect for her needs. The sump actually fills with diesel and has three marks on the dipstick all about the same distance appart...min max and an X the oil will rise towards the x as it gets contaminated.
Apparently they have put bigger bearing in and special oil, still not convinced. I shall be getting rid before end of warranty. My defender is a new 2.2 I shall be looking at chipping and getting EGR off and maybe accidentally losing the dpf innards. Just wan to see where the MOT goes... |

Glad Ive got a 2.4 without the DPF , oh poo my BM has a DPF and 18000 mile service intervals, never used a drop of oil nor noticable gone up, jolly glad Ive given it intermediate oil changes to protect it until the cam chain fails. re fuel in the oil I run a fleet of Cummins NT855s if fuel leaks into the sump you can guarantee bearing damage DEFENDER 90 TDCI XS, I hope everyone is well and your land rovers make you happy |

the diesel in the engine oil problem was really bad for the some vans. we fitted lots of engines for a hire firm near us . all nearly new vans , blamed on short start stop trips , regen started then engine stop ,engine started regen started again and so on filling sumps with diesel

No kidding!! Introducing fuel into the combustion chamber during the exhaust stroke as a cure for high emissions is like shoving a plate of fish & chips up your butt once a week as cure for the indigestion!! To a politician that advice would result in legislation on how to perform the procedure. Actually, I don't think BMW or VW has that problem though, their DPF runs hot enough to work without introducing additional fuel for regeneration, at least as far as I am aware. If I am right you can pull your pants up Sir, your meal will be served in your usual newspaper wrappers!!!! Bon apetite!!! ****CENSORED**** |
