The high inherent lubricity together with their clean burning make the Ketjenlube Polymer Esters an ideal base fluid for two-stroke motor bike engine oils.
The ISO-L-EGD results of four different formulation examples (semi-synthetic, synthetic, high solvent oils) containing Ketjenlube Polymer Esters as ester component are:
