I have an 05 Wide Glide. Manual says 91 Octane. That would be "Premium" where I live.

I have used 89 Octane or mid grade on occasion and found the engine to run smoother, and was especially noticeable when the hand went off the throttle and I changed gears and then went on again.
It was not as jerky as with 91.

Could that be??
