Question

Which has higher energy density petrol or diesel?

Answer 1

Hey.

Here is your answer.

Diesel has higher energy density than petrol .

Diesel and gasoline have roughly the same energy per unit mass (lower heating value), about 41 MJ/kg).

The density of diesel is about 833 kg/m^3 compared to 740 kg/m^3 for gasoline. This gives diesel about 13% higher energy density per volume.

Thanks.
