Performance Characteristics

• Composition: 80 - 84% Low sulfur No. 2 diesel, 15% fuel ethanol, 1 ­ 5% PEC additive package (2% average is expected)

• Cetane: 42 to 45 (using #2 diesel with Cetane of 40)

• Low Temperature Performance: E-Diesel is stable to at least -22 oF (no separation and unlike diesel, does not gel)

• Energy Content: E-Diesel - 126,000 to 128,000 Btu/gal vs diesel ~ 135,000 Btu/gal

• Fuel Economy: Tests to date show about 2%-6% less mileage

• Sulfur: Sulfur is reduced 16 ­ 20% from the base diesel

• Blending: E-Diesel can be "in-line" or splash blended at the terminal using existing equipment, facilities and blending techniques.

• Lubricity: 5,200 vs. 3,100 for No. 2 Diesel

• Water Tolerance: Designed to tolerate water exposure from storage and distribution

• Biodegradable: Readily biodegradable in standard 28 day ASTM test (Method E1720-95)

• Emissions: Testing at Southwest Research Institute has confirmed 41% reduction in PM, 5% reduction in NOx and 27% reduction in CO as compared with No.2 LS Diesel using EPA Federal Test Procedure for heavy-duty diesel engines.

• Cost: Estimate $0.05 to 0.07 above No. 2 diesel (in full scale production). Cost competitive with No. 1 diesel and potentially better than the pricing expected for future low sulfur diesels. Demonstration and pre-production pricing will be higher.
