Glad you got home safe and the Axis ran so well. I wouldn't complain about the 10.2 mpg either. Mine has just under 4,000 mi. on the odometer and I'm only averaging about 9 mpg. 300 mile round trip we went on over the weekend into higher country, I only got around 8.5 mpg driving 60 - 65 mph pretty much loaded. Not interstate travel though and several small towns to pass through and it was a bit windy. I figure mine the old way with a calculator. Perhaps after reaching the 5,000 mile mark, I'll get better performance as well.
Good to know about the fuel tank and you didn't have to push it into the gas pumps.
