I work for an automotive manufacturer, who requires that a fuel sample be taken and analyzed on each diesel vehicle with fuel related problems.
I compiled the results of 102 fuel tests taken over the last year, and averaged the results. These samples were taken from all over the U.S., and should be a decent representation of the 'average' quality of diesel here.
Cloud Point / Pour Point
Cloud Point (ASTM D2500) - 13 °F
Distillation (ASTM D86)
Initial Boiling Point - 349 °F
10% Recovered - 401 °F
50% Recovered - 501 °F
90% Recovered - 610 °F
End Point - 656 °F
% Recovered - 97.57 %
Physical Tests
Viscosity @ 40°C (ASTM D445) - 2.4 cSt
Physical / Chemical
API Gravity @ 60F (ASTM D287) - 35.8 °API
Calculated Cetane Index (ASTM D4737) - 45.7 CCI
Water by Karl Fischer (ASTM E203/D6304) - 85 ppm
Sulfur (ASTM D4294/D5453/D7039) - 12 ppm
