Ah, the never-ending debate of Petro-Canada 94 vs Shell 91. I've searched about it prior, the consensus seems to be "Shell V-Power 91 for better mileage, Petro-Canada 94 for better power".
I haven't done so yet, but my plan is to add ~8 oz of BOOSTane to a 60L tank (~15.85 gal) which according to BOOSTane's charts, should raise it to ~100. If I go with 91 instead, then it would mean ~97, which I'm also wondering if it is good enough for map3...
