I got 52 miles out of the first 12 gal of gas. I could run my diesel forever it seemed in a tank. Over 30 mpg but the Ridge drinks gas worse than my outboard engine on my boat. Do get lots of tank pressure. What are y’all getting in your Ridge. I have the HVAC but lawd I figure it would better than 4mpg. That’s not what I was expecting and my still just putting around finishing the break in period
