Driving across Canada last week (when prices hit the equivalent of $3.93US per gallon) I found many gas stations selling E-Gas. Some had E85, at $1.10CN per liter while selling a 15% blend at $1.19CN.

I was forced (by distance between services) to use the E15 on a few fillups. Mostly from 1/3 to 1/2 tank. The VX took it well, and I showed neither a positive or negative change in economy or performance. I did not attempt the E85.
