hi,
I have to agree , 600 is a very good performance ... 38.7 mpg ... I always do that kind of game but my best record on a journey of 2640km was 7.94 l/100km must be 35.6 mpg. mpg should be the right way to talk about, otherwise some people will have the temptation to go to far and 72 L is to much, they said that it is not good for the engine to stop without diesel it happens nearly one time for me and the defender and was running out of diesel with the Ford Transit of my work. puting some diesel in the tank was enough to go again Phil current : defender 110 sw 2.2 puma 2012 and 230.000km today and again my Range Rover VM2.5 engine from 1992 and 528.000km today. One ten 1988 to 1992 1987 BMW GS80 One Ten from 1984 to 1987 One Ten from 1983 to 1984 Serie 3 109 from 1980 to 1983 from 1974 Jeep CJ3B and CJ6 |

Why is there so much emphasis and interest by some on how many miles you can get to a tankfull? Surely when buying or owning a Defender economy doesn't feature on the list of features or if it does maybe you should be thinking of another marque. Just to add to the topic a mate of mine who's intercooler hose went got relayed back to the south coast, on aggregate his journey taking into consideration the fact it was on a transporter for over 50% of the round trip did rather well...... It worked out over the entire journey he got about 56mpg.  
You really do need to get out more, stop infuriating other road users driving as if you've a caravan on the rear and start enjoying and driving your Defender like it's supposed to be driven and stick a piece of tape over the tripometer.  If you go through life with your head in the sand....all people will see is an ar5e!!
Treat every day as if it is your last....one day you will be right!! |

Travelling at 50-56 mph you are covering the 73-82 feet per second.
Some research has suggested that best distance for slip streaming is about 10 feet away from lorry in front of you. Time taken to cover that 10 feet is about 0.1 second People will argue about reaction time being fast but best results are of the order 0.1-0.2 seconds. However reaction time is not the thing to consider but time from event starting to actually effectively applying brakes and that can well be of the order of 1.5 seconds or about 120 feet at those sort of speeds More details here Now throw in a bit of boredom or distraction then time to effectively apply brakes goes up, distance travel before effective reaction increases etc. Is slipstreaming a wise move? Safety or fuel efficiency? Legality of it with tailgating penalties?? As for running fuel tanks that low in the UK? Personally I head for the nearest fuel station when orange light is on and seldom run tanks less then a quarter full. With a quarter tank of fuel if I need to go anywhere I can without worrying where nearest fuel station is! Run out of fuel and any saving on fuel efficiency is well out of the window with extra costs and time needed to sort problem out Brendan PS edited to add is that 1.5 second time the basis of the 2 second rule for safe distance apart for vehicles?

I do find all this a bit stupid myself as there never going to be great, I appreciate cutting costs but I think you have to be sensible and just drive smoothly accepting there not very good. To put it into context, I know it was naughty in terms of weight but when I bought my last Puma we towed it back on a trailer from Stoke on trent to Essex and managed 38mpg towing it on an ifor williams car transporter. So maybe you'll be best off buying a volvo 4x4 and towing yours every where next, I reckon if you drove smoothly you might even see 40mpg then! Defender puma dormobile camper |

C ' mon guys , give Caterham a break .
He's clearly environmentally friendly and has probably saved a bit of Ozone or rainforest in his 50mph efforts . Good man |

I think that Caterham needs one of these in his life:

my driving is pretty much completely urban, I drive carefully and use the torque android app, I don't find I get better mpg on the motorway, mine is a 09 90 with 285/ 75 / 16 cooper discoverers I was very pleased with my last fillup, if it doesn't get a good blast every now and then I find the figures drop of a little, it does get a bit of an obsession but personally I would never run it dry, I always fill up asap when the light has come on,

well after several fill ups on my scan gauge I'm getting about 26 mpg average driving gently, 1750 rpm appears to be the point at which MPG suddenly trails off.
On a gentle run to Wales I only managed 24 mpg doing no more than 60 mph on the M6 and M54, I can get more locally on slower 40-50 mph B roads. I can understand how Caterham gets high figures, (same model year both 2.4 but I'm a 90) If I am mega gentle and I mean feathering the throttle, extreme miss daisy acceleration, changing up at 1500 rpm and not doing more than 40 mph I can get average figures of up to 35 mpg (on the scan gauge). I cant keep this up however for more than about 5 miles as I don't feel my engine likes it, mine is much happier changing up at 2000-3000 rpm and cruising at 55-65 mph in top gear, and Id rather have a happy engine than a few more mpg. DEFENDER 90 TDCI XS, I hope everyone is well and your land rovers make you happy |

I change up at just below 2000, I have a re map from monster tuning, which I think helps, the bigger wheels make the mpg figures more accurate as it seems to make the speed and therefore mpg read spot on rather than optimistic with stock wheels, its not a case of just driving carefully there is a definite technique to getting good mpg, its more about the right gear for a given speed, it took me a while to suss it, letting the torque drag you along efficiently is the way to go, on the motorway I'd probably get high 20's but I wouldn't be doing 45...
