Gregyeppoon, I am a just-joined member to this forum and I am having the same concern with my October 2009 SR5 D4D manual single cab ute which has 16563 km on the clock. I keep a pretty strict log book of the car's fuel performance as I have done with every vehicle I have owned since 1972. Every day I drive it, I log the kms travelled as well as anything notable about its performance or anything else which needs any kind of attention. My method of keeping tabs on my fuel consumption is to fill the tank to exactly the same visible place in the fuel tank filler pipe (as I have done with all my vehicles) and then calculating fuel used between fills. I usually use the same service station and the same bowser to keep things as consistent as possible. I have the following aftermarket add-ons - ARB bullbar, LRT replacing the standard tank, canopy on the standard tray, light tow bar, and snorkel. Since October 2009 my fuel consumption has remained in the vicinity of a low of 10.2 l/100km (9.7km/litrre) to a best of 11 l/100km (9.11km/litre) which I regard a very poor when compared to my old 2.8 3L single cab ute with the same accessories which I rarely ran at less than 9 l/100km. I bought the KUN 26R on the basis that Toyota rated its fuel consumption at 8.3 l/100km. Fuel consumption is my chief concern when assessing a vehicle suitable for my needs. Both my last Hilux and the present one have had aftermarket cruise controls fitted and used whenever I have a steady run on open highways. I drive conservatively which annoys my mates. My conclusion is that there is something very wrong with the way in which my vehicle pumps fuel to the injectors. The whole principle of the common rail injections system is that it is a much more efficient fuel delivery system. That was why it was invented, and usually, in passenger vehicles, it certainly is. Quite frankly, when I spoke to my local Toyota dealer on the occasion of a recent recall to do with the tail shaft, I did discuss my concerns with the fuel consumption. I mentioned the Hilux brochure stats and he simply said flat out that it wouldn't happen, ie 8.3l/100km. Whilst this figure is perhaps a bit optimistic, I do consider that my brand new vehicle should be doing at least as well as my old vehicle which had nearly 200,000km on a rebuilt motor, and which, right from the time of the rebuild obtained almost the same consumption figure by my method of calculation. Whether my method of calculation is the most efficient, reliable or correct is not the issue. The issue is that at the very least, it is a consistent method of comparison between the two vehicles over time as well as how my vehicle's performance is changing over time. I am pretty annoyed about this. Dennis La Varenne
