I put Octane 94 in my RCF (no ethanol) and definitely I feel a difference in throttle response and midrange torque delivery compared to Octane 91. It also makes sense considering the very high compression of the engine, higher Octane resists heat better than lower Octane fuel upon compression in the cylinders.

Since I will be at a True Racetrack this weekend, and have access to several Fuel choices, I was hoping one of you RCF Racing / Track Day Studs happen to know if any of these would be harmful to my Regular / Unmodified 2017? Bikes I know, Japanese Cars I don't. No, not going to be Tracking it. Just for kicks.
(I deleted the first Bullet since it was just Regular 93 Octane w Ethanol)
The following Sunoco fuels are available at the North Paddock fuel island for credit card purchase only:![Confused](https://www.clublexus.com/forums/images/smilies/confused.gif)
