How long can you go between change-outs?

FUTERRA^™’s excellent oxidative and hydrolytic stability and near zero foaming tendency, ensure that the fluid will last much longer than other EALs and conventional oils.  Our testing shows that FUTERRA^™ has oxidative stability* of 3 to 4 times longer than other EALs, thus resisting breakdown and extending the life of the fluid (*per RPVOT ASTM D-2270) and allowing operators to significantly increase the time interval between change-outs. FUTERRA^™ offers the only 10-year warranty for stern tube applications (restrictions apply).
