I am no longer looking for a quick fix, meaning a 10 dollar solution to my so-called 'problem' with fuel economy. My Trooper has plenty of power, all I noticed is that the rpm at say...60 mph is around 2300 rpm, and compared to an american made vehicle, which is around 1200-1500 rpm or so, is higher, and thus consuming more fuel. I think that if the Isuzu engineers were to put a 5th, or 6th gear into the automatic, they would have the fuel economy solution right there! But this of course mean a total redesign and major re-manufacturing of the vehicle, making them high on the fuel economists lists, but puts their corporate income in the hole, so to speak. I am not sure what Isuzu has done with their new Ascender, but I do like the looks of my Trooper vs. the new Ascender. The Axiom 'looks' like the replacement of the Trooper, and of course it is more stylish and 'future looking' than the trooper, and of course has the same 'ol 3.5 litre engine, which I have found is being manufactured for a whole pile of import trucks, and SUV's. So there is my 2 cents on the fuel economy improvements for the Trooper. My buddy just picked up his new Toyota Highlander, which he 'says' is getting 30 mpg highway, but I can't believe that just yet. But if thats the case, so be it. I am only a new Isuzu owner, and am still keeping my eyes open for the absolute ultimate SUV for my driving style, and utilitarian usage. For now, its setting up a wicked sound system, there is so much room in the back for subwoofers, Yeehaa! But thats a whole different animal for me. Now that was just my 3 cents....... for now.
