Is it normal for that wide range of octane ratings and the highest to be 91?
I don't remember octane ratings in the 80s since maybe the 90s. Here we commonly have 91, 95, and 98 as the options.
North America uses a different scale for octane than most of the rest of the world. 91 AKI is typically about the same as 98 RON.
Ah of course they would. Thanks for the info!
