EXTRA4 is a 100% synthetic triple ester engine oil featuring advanced additive technology. By using today’s most advanced additive systems and high-performance synthetic ester based stocks, we have engineered what we believe to be the finest 4-cycle motorcycle specific oil available on the market today. The very latest shear stable polymer systems have been used to assure viscosity stability and virtually eliminate transmission “shear-down” of the oil. Exceeds API SL and JASO MA specifications.
