You won't notice a difference using different fuels in most low compression
low performance engines. The higher compression and higher performance
engines will run differently with different fuels. I have a turbocharged mid
80's mopar that I don't run anything but chevron in, anything else and it
runs like crap. Exxon seems is my second choice. It has been suggested by
mopar themself that you don't mix fuels(read this in a mopar performance
engine book) because the computers used in cars nowadays take a little time
to adjust to the fuel(adjust timing curves and fuel maps). Most people would
never notice this, but mixed gas does not run as well as pure gas. Try
putting X brand mix gas into your 1000cc 174HP 13:1 compression Jap sport
bike and then try to ride around town, you will see what I mean.
