Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.
13J energy is stored in petrol,
Approximately 34.2 million joules (J) of energy can be released from burning one liter of petrol.
Even the most efficient petrol engines are quite inefficient at changing the chemical energy in the fuel to kinetic energy. Most becomes heat and some turns into sound. Somewhere in the region of 25% becomes turning force into the transmission.
The calorific value of petrol is typically around 32-35 MegaJoules per liter. This means that when petrol is burned, it releases this amount of energy.
One US gallon = 114,000 to 115,000 Btu = 121MJ depending on type.
Diesel and petrol engines work differently. Diesel engines use compression to ignite the air/fuel mixture, and have a much higher compression ratio than petrol engines, which use spark ignition. The conditions for ignition are not met when petrol is put into a diesel engine, and will stall.

A full tank of petrol is worth as much as a full tank of petrol in any other car.
Approximately 20-30% of the chemical energy in the fuel of a petrol car is transferred to kinetic energy to propel the vehicle. The rest is lost as heat through various forms of energy loss like friction, exhaust, and other inefficiencies in the engine and drivetrain.
