Here's the data I collected. The consumption data was for a 1.00 hour run of a 1.5L Isuzu in a 12.5kW Onan/Cummins generator on a load bank set at 6250 watts.
Three GDiesel samples were purchased from three different locations listed on the GDiesel web site. Two control samples were run, Shell and Chevron, both EPA 49 state ULSD.
Density in g/ml at 21C:
Code:
Shell 0.8340
Chevron 0.8303
GD1 0.8306
GD2 0.8286
GD3 0.8282
Calorimetry in calories/gram:
Code:
Shell 10,879
Chevron 10,926
GD1 10,933
GD2 10,925
GD3 10,939
Consumption (grouped by day) in g/hr.
Code:
Shell 2158.17
GD1 2173.26 +0.70%
Shell 2147.51
GD1 2137.92 -0.45%
Chevron 2169.42
GD2 2164.65 -0.22%
GD3 2142.28 -1.25%
The GDiesel showed an average of 0.30% lower consumption compared to the two controls. The average margin of error based on the replicate samples is 1.05%
