100 Octane Should I use it?

Just so everyone knows, for the 2021 Rocket R and GT, here is what the manual says. In the US we use the (RON+MON)/2 system for octane and that is what is labeled on the pumps. In the US when you see E25 or E10 on the pumps, that is the maximum allowed ethanol, not the minimum. An E10 pump could have only 2% ethanol in it, but no matter the percentage, the ethanol won't be over 10%.
