More engine noise (vipec v88 with bosch knock sensor) running on canadian gas. Able to run almost 2 degrees more peak timing on the american gas all conditions being equal. My tuner in the states says our "94" octane gas is like water... it might be even worse than 91 octane California gas.
Have been filling up in Blaine/Point Roberts since 2009.
Edit: maybe when I have time I'll have a friend who works at a lab to test the actual octane in chevron 94...

I am glad you posted this here too.
It was because of this thread that I asked you what gas you use.
