I run Sidewinder Worlds 30% in all my race vehicles. My team members run 20% in gas trucks(to keep power down) I have had great luck with morgan fuels. Besides performance, you dont need to run after-run oil.
All good stuff. These companies all use high quality products , without unwanted byproducts. All offer diferent blends and all are worth trying in my eyes. Along with a few others , just havent gotten to test out those yet.
