High Octane

When my 05 Fat Boy was delivered (carbed) I was told by the tech that I needed to use the high test gas or the highest octane fuel for the bike. Any truth to this? Can I skimp here? I won't if I shouldn't.

RE: High Octane

What does your owner's manual say?

The owners manual says the bike requires 91/92 octane fuel.

RE: High Octane

Never ran a lower octane. Try to get 93 octane which is the highest around here. Is weird that bike gets different gas mileage with different brands of gas. Has anyone else noticed this?
