Where would I find good 98 in/around Toronto?
a simpler solution. Find out which of the octane boosters for sale work, then add that to the 91 or 94 octane you are using.
I`m hoping there is a race supplier somewhere someone has used and can report on. Also Ive been advised against octane boosters. Maybe there is good ones...I dont know.
I used to drive out to Mississauga, Competition Fuels weekly. Fill the car and some jerry cans. 101 octane. Wow what a difference!

Octane boosters = crap. try calling Autowerks in Woodbridge (905-850-7600). I'm pretty sure they will be able to point you in the right direction.
