If i was to do this ,how much would the octane number be,or it cant be done.If it can what ratios should i run,reason i ask is that its going to be way cheaper if they are both mixed

 

Well, with seven gallons of 93 and three gallons of 116 you would be at 100 octane.

What octane level do most of you guy shoot for?

 

High Octane Fans out there? Have you tried Avgas (aviation fuel)? I use it exclusively on my heavily modified Sea-Doo because of the high compression.

It's not 110 Race Gas, but it IS 103 octane at $1.98 a gallon (beat that VP Race Fuels!). I've been using it for years, and just fill up (trailer and all) at the small private airport nearby.

 

Becareful of AVGAS, most of which is leaded.
Leaded fuel + rotary = clogged cats and bad O2 sensors.
