More than three years of laboratory bench testing, dynamometer testing under accelerated conditions, open road and closed course durability testing, wear and deposit rating analysis and sophisticated used lubricant analysis went into producing the optimal combination of three synthetic basestocks and carefully chosen mixture of additives which offer superior lubrication and cooling, as well as protection against rust and oxidation. Screamin’ Eagle’s more than half a million miles and 500-plus hours of dyno testing proved that in addition to reduced oil consumption, SYN3 also provides high temperature film strength, which means the lubricant maintains film thickness in high power output and high engine speed conditions, keeping the metal parts from rubbing against each other and resulting in less wear.
