air density?
Jon: Glad to see on the board again- The high temps have an adverse impact on the performance - My mpg fell off on my last run to Nashville (600 miles round trip) at 100 degrees from 7.82 to 7.37 mpg. Do you think the temps are the problem, I have looked at everything from tire pressure, wheel bearings, brake drag, air cleaner, fuel filter, etc that I can think of. I did run the OTR air all the way. No good answer other than diesel fuel cost more now and am enjoying it less.
Bling the crap out of em Jon!
Roger that!
