Out West you have a real hard time finding a 93 octane gas most all gas stations have 91 octane. With the mods on my bike I get some spark knock from the 91octane gas. Here in the Midwest you can't get 91 octane gas it is mostly all 93 octane and I don't get the spark knock from the 93 octane like I would from the 91 octane. When you get into Wyoming and Utah the regular fuel is 85 octane and some of the remote gas stations would only carry regular gas so I carried some Lucas octane boost just in case I could only get regular gas. I used the Lucas octane boost a couple of dozen time and I never had anything go wrong or break on my bike, I would only use a splash of the octane boost when needed and I never used it on a regular basis. I did run the bike on 87 octane gas once when I did not have octane boost and you sure can tell the difference between having the octane boost and not having the octane boost in the tank. It is your choice on carrying the octane boost but the bike will run on 87 octane fuel in case of emergency without octane boost and you will get to a gas station that sells premium gas just fine.
