a combustion power supply assembly positioned in the housing assembly; a fastener supply assembly configured to receive fasteners and supported by the housing assembly; a fastener driving assembly positioned in the housing assembly; a trigger mechanism assembly supported by the handle assembly; and a workpiece contact element assembly supported by the housing assembly. ### Claim 2 (depends on 1) The combustion powered fastener driving tool of claim 1, where the clean oil lubricant is a light mineral based oil with a viscosity lower than 200 Saybolt universal second (SUS) at 100° F. using the American Society for Testing and Material (ASTD) D 445 method. ### Claim 3 (depends on 1) The combustion powered fastener driving tool of claim 1, where the clean oil lubricant is a light mineral based oil with an evaporation time lower than 200 hours per gram at 120° C. ### Claim 4 (depends on 1) The combustion powered fastener driving tool of claim 1, where the clean oil lubricant is a light mineral based oil that does not gel or solidify with time under the combustion powered fastener driving tool operating conditions. ### Claim 5 (depends on 1) The combustion powered fastener driving tool of claim 1, wherein the clean lubricant is a light mineral based oil, and wherein the mixture of hydrocarbon fuel and clean lubricant is approximately 98% fuel and approximately 2% clean lubricant. ### Claim 6 (depends on 4) The combustion powered fastener driving tool of claim 4, wherein the clean lubricant is a light mineral based oil, and wherein the mixture of hydrocarbon fuel and clean lubricant is approximately 99% fuel and approximately 1% clean lubricant. ### Claim 7 A combustion powered fastener driving tool combined fuel supply and clean lubricant supply container assembly comprising: a container; a hydrocarbon fuel in the container; and a clean lubricant in the container. ### Claim 8 (depends on 7) The combustion powered fastener driving tool and clean lubricant supply container assembly of claim 7, where the clean oil lubricant is a light mineral based oil with a viscosity lower than 200 SUS at 100° F. using ASTM D 445. ### Claim 9 (depends on 7) The combustion powered fastener driving tool and clean lubricant supply container assembly of claim 7, where the clean oil lubricant is a light mineral based oil with an evaporation time lower than 200 hours per gram at 120° C. ### Claim 10 (depends on 7) The combustion powered fastener driving tool and clean lubricant supply container assembly of claim 7, where the clean oil lubricant is a light mineral based oil that does not gel or solidify with time under the combustion powered fastener driving tool operation conditions. ### Claim 11 (depends on 7) The combustion powered fastener driving tool combined fuel supply and clean lubricant supply container assembly of claim 7, wherein the mixture of hydrocarbon fuel and clean lubricant is approximately 98% fuel and approximately 2% clean lubricant. ### Claim 12 (depends on 7) The combustion powered fastener driving tool combined fuel supply and clean lubricant supply container assembly of claim 7, wherein the mixture of hydrocarbon fuel and clean lubricant is approximately 99% fuel and approximately 1% clean lubricant. ### Claim 13 A pneumatic powered fastener driving tool comprising: a housing assembly including a main compartment assembly and a handle assembly extending from the main compartment assembly; a clean lubricant supply container positioned in the housing, and configured to contain a clean lubricant; a power supply assembly positioned in the housing assembly; a fastener supply assembly configured to receive fasteners and supported by the housing assembly; a fastener driving assembly positioned in the housing assembly; a trigger mechanism assembly supported by the handle assembly; and a workpiece contact element assembly supported by the housing assembly. ### Claim 14 (depends on 13) The pneumatic powered fastener driving tool of claim 13, where the clean oil lubricant is a light mineral based oil with an evaporation time lower than 200 hours per gram at room temperature. ### Claim 15 (depends on 13) The pneumatic powered fastener driving tool of claim 13, where the clean oil lubricant is a light mineral based oil that does not gel or solidify with time under the pneumatic powered fastener driving tool operation conditions. ### Claim 16 A pneumatic powered fastener driving tool clean lubricant supply container assembly comprising: a container; a clean lubricant in the container; and a connector configured to connect the container to a housing assembly of a pneumatic powered fastener driving tool. ### Claim 17 (depends on 16) The pneumatic powered fastener driving tool clean lubricant supply container assembly of claim 16, where the clean oil lubricant is a light mineral based oil with an evaporation time lower than 200 hours per gram at room temperature. ### Claim 18 (depends on 16) The pneumatic powered fastener driving tool clean lubricant supply container assembly of claim 16, where the clean oil lubricant is a light mineral based oil that does not gel or solidify with time under the pneumatic powered fastener driving tool operation conditions.
