In 1992, FERIC began a two-year operational evaluation of Binol Hydrap - a non-toxic, biodegradable, canola-based hydraulic oil - in a forestry application. The study monitored the use of Binol Hydrap in a Barko 145A log loader mounted on a Kenworth log truck working in the east Kootenay region of British Columbia. This report discusses the results of the evaluation, and the experience of converting a hydraulic system from mineral oil to a canola-based oil.
