                 o  Loss of full power performance on certain power-limited
                    vehicles.  Certain vehicles such as the M88 ~ecovery
                    Vehicle which are already somewhat power  imited with
                    diesel fuel will experience additional loss of pulling
                    power when using JP-5 or JET A-i.

4.   Can JP-5 or JET-i be used in gasoline-fueled ground vehicles/equipment?

     Answer:  No.  Kerosene fuels cannor be used in any spark-ignition engine
              systems.

S.   Are there any additives you can add to JET A-t or JP-5 to enhance smoke
production when the fuel in introduced into the VEESS?

     Answer:  No.  There are no additives available to date that can enhance
              the smoke production qualities of JET A-i or JP-5 when these
              fuels are introduced into VEESS of armored vehicles.

6.   Will using either JET A-i or JP-5 cause a significant increase in fuel
consumption?

     Answer:  No.  From information generated to date, there has been no
              indication of a significant increase in fuel consumption being
              evidenced.  One may anticipate a slight increase (i.e.,  1-5%)
              as this is due to the lower volumetric heat of combustion
              (Btu/gallon) of JET A-1/JP-5 when compared to diesel fuel.

7.   Will using either JET-i or JP-5 plug fuel filters on vehicles?

     Answer:  No.  3oth JP-S and JET A-i are inherently cleaner fuels when
              compared to diesel fuel and they will not therefore cause fuel
              filter plugging.

8.   What causes filter plugging?

     Answer:  Plugging of filters is caused by either high particulate con
              tamination (i.e., dirt, insoluble particles, etc), fuel
              deterioration products (i.e., oxidized reaction products, inso-
              luble gums, etc),  presence of microbiological organisms,
              emulsions produced by residual water bottoms in fuel tanks, or
              a combination of these.

9.   Can either JET A-i or JP-5 be directly added to vehicles/equipment con-
taining diesel fuel in their tanks?

     Answer:  Yes.  There is no problem as both JET A-l and JP-5 will instan
              taneously mix with the residual diesel fuel in the fuel tank.
