Yea I'm stoked! On my trip from San Diego, CA to Pahrump, NV with a fully loaded vehicle I avg a 44.6 mpg tank in my ECO. That was at an avg speed of 53 mph. On my way back to San Diego today I avg a 48.5 mpg tank at an avg speed of 60.3 mph! I lauged at a Prius that passed me on the road saying "i'm getting better MPGS!" lol. Lets hope I can keep my mpgs above 40mpg on my daily comute, I've only been avg between 37 and 39 mpgs.
