Technical Abstract: Oils from new crops such as lesquerella (Lesquerella fendleri), field pennycress (Thlaspi arvense L.), meadowfoam (Limnanthes alba L.), and cuphea PSR-23 (Cuphea viscosissima × Cuphea lanceolata) were investigated and compared with vegetable oils from commodity crops such as castor, corn, and soybean. Each oil was investigated in three grades of purity: crude; refined bleached deodorized (RBD) and further purified over a silica column. Properties investigated include: fatty acid profiles, physical properties (density, viscosity, viscosity index, etc.), pour point, cloud point, oxidation stability, 4-ball anti-wear friction and wear. In general, the new crop oils were found to have specific unique advantages over traditional commodity vegetable oils. Spider plots were used to compare new crop oils on a defined goodness scale to commercial oils.
