Wikipedia states that the molar heat capacity of gasoline is $228 \, J/mol\cdot K$ (https://en.wikipedia.org/wiki/Table_of_specific_heat_capacities). This is more than twice that of liquid water ($75.327 J/mol\cdot K$) which is regarded as having a very high molar heat capacity. This got me thinking whether the high heat capacity of gasoline has any positive or negative affects on its use in engines or in other industries?
The fact that gasoline has a high molar heat capacity would mean that it takes a lot of heat energy to warm up gasoline to a given temperature relative to other working fluids. So surely this would make gasoline an inefficient fuel in a heat engine relative to something with a lower molar heat capacity like water or even a simple monatomic gas like helium? If this is the case then why is gasoline used extensively in heat engines? Does the large amount of energy stored in its chemical bonds act as a positive that simply outweighs the negative of its high molar heat capacity or is the high molar heat capacity of gasoline even a negative to begin with?
Any help on this issue would be most appreciated!
