<VV> Higher Octane Fuel

[Les]

No idea what the legalities are in all the areas of the world where 
VVers live, I was answering a technical question.

In Canada, you're paying a ton of tax on fuel whether it's road or 
aviation. Can't tell you whether it's more for road or AV, but it all 
goes to the government's general revenue.

I know you can't use purple (farm) gas in your non-farm vehicle. I 
wonder if you can use it in an airplane? What if you're using the plane 
to spray your field?
