hello, i have a 2007 GSXR 750, im just wondering which gas is ok for the bike. i know that obviously, the most expensive gas is the best for any vehicle. i am just wondering if there is much difference between gas brands? like supreme for chevron is 92 octane, and regular is 87 octane. where as husky and mohawk have their regular gas at 90 octane. Is it ok to use the husky or mohawk brand? which octane is ok? i have been using spreme (92 octane) and supreme plus from chevron. thanks.
