Well, here is my experience with 100 octane gas.
I lived in Japan for a while and frequently used 100 octane from mobile, esso,
shell etc. To be honest I really could not tell the difference when I filled up regular vs 100 octane. Come to think of it, in Japan the regular is around 90 to 93 octane. I am pretty picky about what I use for my car so it's not like I wasn't paying any attention. Especially when a Litre of 100 octane gas costs around $1.50. (that's about $5/gallon) Sometimes you just couldn't justify filling up with 100 octane gas. The difference is minimal. The only major difference I felt is in the engine knocking when running low rpm's in a high gear.
