no E85 here in Vancouver. The nearest is a shell in Washington. 1401 172nd St., NE, Marysville, WA . it is in lakewood area close to I5.
That is what I use for track days. Almost fill with Chevron 94, here in Van it has no alcohol, and 1 gallon of E85. I tried double that mixture and the car did NOT like it.
When I go to Wash and Oregon tracks I take down 2 jugs of Chevron 94 as all Washington has alcohol in their gas, and fill them with e85 on the way home.
Yes it works. The car is noticeablly cooler running on the track. And Map 5 on JB4 will tune to the fuel. Yes LOTS more fun.
If you do not mind paying the money instead of going down, you can get a gallon of stove ethanol at Steveston Marine, "Captain Phab's marine alcohol" $16ish a gallon
