         2 . The fuel composition of  claim 1 , wherein the amount of said renewable based component is in the range between 0.1 vol. % to 50 vol. %, based on the total volume of the fuel composition. 
     
     
         3 . The fuel composition of  claim 1 , wherein the amount of said renewable based component is in the range between 0.1 vol. % to 35 vol. %, based on the total volume of the fuel composition. 
     
     
         4 . The fuel composition of  claim 1 , wherein the amount of said renewable based component is in the range between 0.1 vol. % to 20 vol. %, based on the total volume of the fuel composition. 
     
     
         5 . The fuel composition of  claim 1 , wherein said renewable based component comprises isoparaffins. 
     
     
         6 . The fuel composition of  claim 1 , wherein said renewable based component comprises normal paraffins. 
     
     
         7 . The fuel composition of  claim 1 , wherein said renewable based component comprises hydrocarbons that are derived from natural, replenishable feed stock which can be utilized as source of energy. 
     
     
         8 . The fuel composition of  claim 1 , wherein said renewable based component is selected from the group consisting of a product derived from hydrotreating a material of biological origin, a product derived from the transesterification of a material of biological origin with an alcohol, a product derived from reacting a fatty acid with an alcohol, a biomass pyrolysis bio-oils, a biologically-derived oils, alcohol; other oxygenate; vegetable oil or vegetable oil derivatives, and any combinations thereof. 
     
     
         9 . The fuel composition of  claim 8 , wherein said material of biological origin is selected from the group consisting of vegetable oils, vegetable fats, animal fats, fish oils, algae oil, and any mixtures thereof. 
     
     
         10 . The fuel composition of  claim 1 , wherein said renewable based component comprises a renewable diesel produced by hydrotreating triglyceride containing feedstock in the presence of a catalyst. 
     
     
         11 . The fuel composition of  claim 1 , wherein said petroleum based component comprises a hydrocarbon derived from petroleum refining process. 
     
     
         12 . The fuel composition of  claim 1 , wherein said petroleum based fuel comprises a fractional distillate of petroleum. 
     
     
         13 . The composition of  claim 1 , wherein said petroleum based component is selected from the group consisting of a middle distillate fuel, a jet or turbine fuel, automotive diesel fuels, railroad diesel fuels, heating oils, industrial gas oils, distillate marine fuels, kerosene fuels, light and heavy cycle oils, Fischer-Tropsch fuel, and any mixture thereof. 
     
     
         14 . The composition of  claim 1 , wherein said petroleum based component comprises diesel base fuel having boiling points within the range of 150° C. to 400° C. 
     
     
         15 . A method for preparing a fuel composition comprising blending petroleum based fuel and a renewable based fuel, wherein at least 20% of the compounds in said petroleum based component having boiling point range equal or greater than the boiling point of said renewable based component.
