Everybody has their preference. I just run the low grade stuff myself without any problems. I'm not a dragger or knee dragger either.
Thank you for the clarification. I have ben running the Cheveron high octane. Will be checking out the "inexpensive stuff"WELL WAIT, I said lower octane, NOT the cheaper stuff. Someone posted that they were running some shop-n-go fuel and the Busa stumbled, they switched to Mobil 93 octane and it was fine. I argued that it was probably the Mobil vs. Shop-n-Go that made the difference. I suggest always trying to stick with the big petro refiners. In fact, I shoot for Chevron because the Technon detergent additive does in fact work. If that's not available, I shoot for 76, then Exxon, etc.
Run the good stuff, just not the highest octane stuff!
