Hi Jahwerx:
___Insighter’s have been scavenging CAT heat and using Radiator blocks for years. See my sig
The parts that are missing is the ability to warm up the fuel (ala VW’s Diesel fuel pre-heater) and seal up the block/engine compartment for maximum heat retention. For an OEM overall solution, this stuff costs real money with the controllers to maintain optimum temps but it has been done. Do a lookup on the PNGV from Ford. IIRC, they had movable front intake louvers for this exact reason.
___I have not seen C&D latest but their FE usually sucks to put it bluntly other then the one time they setup a draft block behind an Excursion for an Insight. 121.7 mpg was the result. About 4 better then my best without any such assistance
___Jerome, there is a difference between Winter Oxygenated and Summer Oxygenated fuels. Both may have upwards of 10% ethanol (that is what we have here in the Midwest) but the winter blend has even more Oxygenates which reduce ones FE by anywhere from 2 - 5%. The 5% number came about from one of my own actuals on 10/24/04 on a second tank of the garbage. 70 + degree temps and a nice tail wind over the segment distance. This 108 would have been an easy 112 - 114 using non-Winter blend 10% Ethanol on that particular day
___Good Luck
