    PRODUCT                          USER RECOMMENDATIONS


FUELS                        Use only primary or alternate fuels.
                             Do not use heavier fuels such as "Bunker Diesel
                                Fuel Oil" fuels as these are emergency fuels.
                             Water contamination due to condensation in fuel
                                tanks/cells must be checked daily to prevent
                                microbiological growth problems.
                             Wherever possible, check to ensure that Fuel
                                System Icing Inhibitor (FSII) is being used
                                to control microbiological growth.   If not pre-
                                sent, FSII should be added (see "Fuel and
                                Lubrican~ Recommendations" Chart).

                             Do not add engine oils (OE/HDO) or DEXRON
                                automatic transmission fluid to JET A-1/JP-5
                                fuels to improve their "lubrication qualities".
                                Adding these oils provides questionable bene-
                                fit, but can cause increased nozzle/injector
                                deposit problems and possible ring sticking
                                tendencies.

                             The Diesel Fuel Stabilizer (MIL-S-33O2l) should
                                be added to any diesel fuel being used as a
                                means to control possible injector/nozzle
                                fouling problems and increased fuel filter
                                plugging.  The high ambient temperatureb
                                coupled with the modes of vehicl~ operation
                                and anticipated lower thermal stability of
                                commercial diesel fuels refined in that
                                region will lead to increased fuel system
                                maintenance.

ENGINE OILS                  Vehicles/equipment arriving from
                                Depot/CONUS/OCONUS locations should be
                                checked to assure that   the proper oil/lube
                                and designated grades are being u~ed.   If
                                unable to identify, drain and replace with
                                recommended product (see "Fuel and Lubricant
                                Recommendations" Chart).

                             Vehicles/equipment operating in higher ambient
                                temperatures and using diesel fuels con-
                                taining higher fuel sulfur content (i.e., up
                                to L %) as will be the case require more fre-
                                quent oil drain intervals.   Recommend that
                                mileage/operating hour/time required for nor-
                                mal oil change be reduced by factor of two.
