Used oil must have been refined from crude oil or made from S3UI-thetic materials. Animal and vegetable oils are excluded from the Environmental Protection Agency s (EPA s) definition of used oil. Oils used as lubricants, hydraulic fluids, heat transfer fluids, buoyants, and for other similar purposes are considered used oil. 

Vegetable oils have shown potential as biodegradable lubricants in applications that include engine oils, hydraulic fluids, and transnussion oils [2-8]. Rudnick [8] and Erhan and Asadauskas [9] have reported on lubricant-base stocks based on vegetable oils. Environmentally acceptable hydraulic fluids, based on vegetable oil-base fluids, have been reported by several researchers [10-12]. 

Chem. Desetip. Telomerized polyunsat. vegetable oils CAS 68956-68-3 EINECS/ELINCS 273-313-5 Uses Lubricant and vise, modifier for engine lubricants, hydraulic fluids, industrial greases, paints/coatings, plastics, and textile lubricants as base to incorporate other functional additives into a lubricant such as antiwear, detergenL and antioxktation compds. 

The use of a series of vegetable oils including canola oil as base fluids for industrial and automotive applications has been discussed in the Uterature (Erhan and Perez, 2002). These vegetable oil-based products were prepared by chemical modifications of the epoxidized vegetable oils to produce environmentally friendly hydraulic fluids, lubricants, metalworking fluids and diesel engine oils. Environmentally friendly, nontoxic and biodegradable motor oil based on canola (Johnson et al., 2002) has shown superior properties compared with synthetic and conventional motor oils. 

Vegetable oils are also being looked at as replacements for motor oils and hydraulic fluids. Tests of a sunflower seed-based engine lubricant manufactured by Renewable Lubricants of Hartville, Ohio, have shown satisfactory lubricating ability while lowering particle emissions. In addition, Lou Honary and his colleagues at the University of Northern Iowa have developed BioSOY, a vegetable oil-based hydraulic fluid for use in heavy machinery.
