Amazing. Mine is an 12v 4.2TD auto on 285 BFG muds with a large roof rack and I think I get circa 20mpg. I've got some long runs this week and will stick to all of the speed limits and see how it comes out but I doubt it will be as 'good' as 25mpg.
Well done Frank.
Mine is a 12v 4.2 non-turbo HZJ manual on 305 GGAT2s with a large roof rack and I think I get circa <= 20mpg (just less than 14.5 ltr/100km).
