Hi everyone I am new to the Hypermiling , I have a 95 eclipse 5 speed manual w/ a 2.0L 4cylinder. What kind of mileage do you guys think is possible without some of the more hardcore things like aero mods and such. I had been getting around 30mpg first few tanks of gas before trying harder for good mileage which then led me to my best tank of almost 39mpg so far. I just got a kiwi MPG guage, today is the first time I was using it and although it is definatly not calibrated yet, I realized when I am driving a steady speed on the highway it will say around 40mpg then I will let off the gas and coast it will go up to 80mpg or so but then if I push the clutch in or put it in neutral it will drop to 25-30mpg, why would it show 25-30mpg when coasting at 55mph when engine is idleing but show 80mpg at same speed with engine at a higher rpm? Is this a problem with the kiwi? Do you scanguage guys have this problem at all? My car does not have a maf it uses a map sensor so I know this will sometimes mess with things of this nature but I do not know.
