Renegade SX4 is our best four-stroke fuel for mortal budgets. SX4 is specifically designed for today’s sophisticated, high-revving single and multi-cylinder four-stroke engines. Formulated with today’s most advanced, fast burning blend components and high quality oxygenates, SX4’s real-world performance reviews speak for themselves. Extensive testing enabled us to create a fuel that no only makes huge power on the dyno, but also delivers incredible performance on the track where it counts. SX4 simply delivers better throttle response, while a blend of proprietary additives inhibits gumming and swelling of rubber components. SX4 works great in today’s modern sport bikes and has shown up to 6% power increases over comparable fuels on the market.
