update, even with ac running, city mpg is all over the place but definitely improved. some trips read out at 82,mpg, some 99.9 mpg, and the lowest and worst trip being 66 mpg. these are all with the side mirrors back on too btw, only focused on wheel spats.
biggest thing is i can FEEL a difference with them on and off. the car feels slippery, less pull or suction or turbulance when driving. pedal doesnt need to be pushed as far down. its hard to explain the muscle memory, but you can for sure feel a difference when driving. ive taken them on and off several times.
doing 250 mile MOSTLY interstate drive round trip down to quartzville creek tuesday. hoping to get a longer mile sample size at just only interstate speed driving with the wheel spats. hypermiling at city speeds or on back country farm roads at 55mph or less isnt giving me a hard clear number, so i will report back!
