The three fuels you listed are great fuels,but you should include Byron in that list and when Byrons new RACE GEN2 fuel comes out, you may end up changing your mind which is the "BEST".
Byron Fuels says the new RACE GEN2 will set a new standard in RC car fuel.
The Losi fuel is just a good fuel ,its nothing to brag about.

If the Byron's race fuel is as you say, then they can be consider with the top three. But until then, the current fuel is break-in fuel to me. You can run under race tunes (temps 240-260), but the life of your motor goes down quickly compared to those top three.
You say, "Byron Fuels says the new RACE GEN2 will set a new standard in RC car fuel." Look who you are getting that from! They are promoting and marketing with the best of them. Until that fuel is raced by racers and it performs at a high level, their words are all talk!
