Two-stroke engine keep-clean data is presented to demonstrate the deposit removal capabilities of a premium fuel additive. In this testing, the fuel additive was added as a top-treatment to a 50:1 blended fuel-oil mixture. Engine testing was conducted on an EchoTM SRM-265 (25.4 cc) string trimmer run under a standardized test cycle. Test measurements included piston deposits, ring deposits, and exhaust port blockage. In addition, a more complete data set was analyzed and several variables were investigated including: different base gasoline fuels, ethanol level (E0 and E10), additive dose (none, low, and high), and fuel stabilizer dose (none and high). Post-test inspection of engine parts using fuel additives showed a high level of clean surfaces, which maintained the engine at its original performance.
