I don't know how a Ultraguage calculates MPG, but a SGII has to be calibrated to a specific blend figured that out with the Stratus so had to use tanks for calculations

I'm playing with the Cobalt now and the factory guage seems to be reading OK. My testing is still early and using pretty short fills so going to rely on the factory guage not tank fills trying to squeeze as much E70/85 in as I can.

E0 last 3 tanks have been in 44-45 range.
E13 car indicated 44.8
E38 car indicated 40.1
E45 after 70 mile me driving car indicated 37 (only down to 35.4 after 210 wife miles)

I'm calculating E% based on the local tuners say all E85 is actually E70, one of these day I'll get a gradulated cylinder to measure blend %.
