Pollution from the petroleum oil is increasing day by day in terms of CO2, CO, NOX, and many other gases and particles. Price difference and economy leads people toward the use of alternative fuels. To overcome this problem turpentine oil is mixed with petrol and diesel and taken as different samples. Then the properties like flash point, fire point, cloud and pour point, calorific value, carbon content test, ash content test, copper corrosion test are analyzed at various proportions of turpentine oil (5%, 10%, 15%, 20% of 100 mL sample) blended with petrol and Diesel fuels. Any other type of substance, can be assigned some physical and chemical properties (e.g. density, thermal capacity, vapour pressure, chemical formula, etc). However, most of the times, combustion properties are also assigned to blended fuels, in spite of the fact that these properties depend on the oxidizer (e.g. air, pure oxygen) and the actual process (e.g. the explosion limits depend on the boundary conditions for a given fuel/oxidizer pair). Fuel price, availability, risk, and so on, could also be considered fuel properties (attributes).
