Anyone test Renegade fuel ?

I think many of the 'new' names in the fuel business are offshoots from when the Torco empire crashed. I found Torco to be very similar to Sunoco. Good fuel, and stable.

Remember when testing different fuels you may need to change your jetting. Different fuels can have different sized fuel molecules, changing your mixture.

Michael is correct as usual . Changing to different brands of race gas , even the same octane rating , will sometimes require a jet change and always requires checking the float levels . The jet change is only required if the specific gravity ( density ) of the fuels differs by more than 2% . For instance going from .710 SG to .715 SG would require no jet change . However , going from .710 SG to .721 ( or the other way around ) would probably require a change in jetting of 1 step . The plug readings will be your guide .And any change at all in specific gravity means it would be a good idea to check the float levels in the carb (s) .
