XS-Evo - Ultra Blaze
Before FIA Appendix J (2014), XS Evo was FIA regulated and used by many of the top teams in Europe. Its unique technology made this fuel used by many teams due to the power and torque gain. XS Evo can be an option for engines with low compression ratios, the high combustion speed allows for fast acceleration. XS Evo is still available to be purchased but is no longer a FIA regulated fuel.
