Gas Oils are defined as a middle distillate, predominantly of carbon number range C11 to C25 and range of distillation is 160°C to 420°C. Gasoils are produced via the lowest fraction of crude oil atmospheric distillation, moreover heavy gas oils are produced by residual vacuum predistillation from atmospheric distillation. GasOil/Diesel distils between 180°C and 380°C. many grades are available due to the uses: Gas Oil for Diesel compression ignition (cars, trucks, marine, etc.), light heating oil for industrial and commercial uses and other gas oil including heavy gas oils which distil between 380°C and 540°C and are used as petrochemical feedstock.

The specifications of the recent fixtures put Iranian gasoil as a prime candidate for desulfurization and blending Platts website says.
Among the other Iranian ports, Bandar Abbas exports 6-7 cargoes of 5,000 ppm (0.5%) gasoil each month, National Iranian Oil Company said, while port Lavan Island supplies one cargo on average of maximum 500 ppm gasoil.
