6. JP-8 Fuel In Caterpillar Engines JP-8 Fuel In Caterpillar Engines Caterpillar Has Allowed The Use Of JP-8 Fuel Catalytic Converter Reliability and Durability Concerns With High Sulfur Fuel

7. JP-8 Fuel JP-8 Fuel Current JP-8 Fuel Specification (MIL-DTL-83133E) Allows Sulfur Levels Up To 3000 PPM Sulfur Levels For Commercial On-Highway Fuel Is Currently Regulated at 500 PPM (15 PPM 2006) Fuel Used For Certifying Engine Emissions Is Regulated By EPA (or EEC)

8. Using JP-8 Fuel Using JP-8 Fuel 7 - 12% Reduced Power Less Energy In A Gallon Of Fuel Means More Fuel For A Given Mission Engines Will No Longer Be Emissions Compliant

9. Aftertreatment Reliability  Over 80,000 in service  No service required Durability  Stainless steel construction  Low skin temperatures
