The average is about 114,000 Btu. The energy content of diesel fuel is between about 128,000 and 130,000 Btu per gallon (lower heating value).[/quote] <br /> <br />http://www.pure-energy.com/products/e-diesel.html <br /> <br />[quote]QUOTE: Energy Content: E-Diesel - 126,000 to 128,000 Btu/gal vs diesel ~ 135,000 Btu/gal[/quote] <br /> <br />http://www.ext.nodak.edu/extpubs/ageng/machine/ae1240w.htm <br /> <br />[quote]QUOTE: <br /> Fuel Heat of Cetan Viscosity <br /> Weight Combustion Number Centistokes <br /> <br /> Lbs./gal.
