Do you guys fill ur pride and joys up with standard unleaded, or do you choose ultimate?

  • 89 seems to work well. 750 aero. 87 seems to sluggish. 93 is a bit over board for 750. Maybe good for 1100

  • I only use 87. I fueled with 93 once and the bike ran funny and backfired a lot.

  • MY 1998 1100 hates premium! Seems to run worse! Go figure.

  • I use 100% gas any time I can our citgo station here carries it.

  • 87 is best

  • I use 87 in my 750, nonethanol if I can find it... but rare here in PA.

    Tried higher octane and it ran like crap.

  • Ultimate

  • I have 209,000 miles on my 04 Aero , always use 87 octane with no carb work !

  • I put ultimate and every few tanks Seafoam

  • Top notch.
