2002 Chevy Suburban 1500 4x4, wife driving, 5.3 FFV. Davidk0031 fuelly.com

E10 15.2mpg 30 tanks
E85 12.4mpg 35 tanks (-18%)

1998 Dodge Stratus, 2.4 auto, preliminary data, in order they were collected this earlier spring. (assumed E85 was 85% could have been 70%, drops blends about 5%) SGII of no value as has to be recalibrated so tank to tank is only way to check mpg.

E30, 2 tanks back to back, 28.4 mpg (-11%)
E0 2 tanks back to back 31.9 mpg
E10 3 tanks back to back 30.5 mpg (-4%)
****replaced all of rear brakes*******
E25 1 tank* 33.5 mpg
E44 1 tank 30 mpg
E0 1 tank 35 mpg, best tank ever but E44 still cheaper per mile

* - Fluke tank maybe, but I'm driving better and warm outside.
