yeah it's pretty crazy how much energy is in fuel.

1 kg of oil contains about 30 MJ of energy. enough to accelerate an object of the same mass to 7.7 km/s. which is almost escape velocity on earth (11.2 km/s), or enough velocity to shoot the object out of earth's gravity field altogether.

(a kg of oil, ofc, costs about $1)
