<div class="htmlview paragraph">This bench test for lubricity of diesel fuels employs a crossed-axis roller on cylinder geometry. The roller on cylinder lubricity evaluator (ROCLE) yields a dimensionless lubricity number (LN) based on the ratio of wear area stress to Hertzian contact stress, all divided by the stable coefficient of friction.</div> <div class="htmlview paragraph">Fuels yielding LN's greater than 1.0 are judged satisfactory. A range of lubricity numbers from 0.5 for kerosene to 1.7 for canola vegetable oil provides good tribological discrimination between various fluids. The addition of 2% canola methyl ester to low sulfur No.1 diesel produces equivalent lubricity to No.2 high sulfur diesel fuel.</div>
