This is my best trip so far. Maybe my best tank so far. I was coming down I-80 from park city (parlies canyon). I usually for get to p&g but this time I did. I didn't need to use the gas the only reason I went back in to gear was to keep me from going 90+ mph. I was coasting in an out of gear. When I got off of I-80 my scangauge said 53.5 mpg for 30 miles. On I-15 I just stuck the cruise control at 60 and kept it didn't need to change it till the just before I got off. Lost a few mpg but still really good. By the time I reached my destination I was at 50.1 mpg for 44.7 miles. And I think that should be higher because my scangauge is not calibrated all the way yet.
