What is the main fuel used for Diesel engines?

Diesel engines, especially on ships, rely on a marine diesel fuel formulated for naval service. This fuel is F-76, designed to meet the specific needs of shipboard diesel engines with the right viscosity, lubricity, and storage characteristics for sea duty. Aviation fuels like Jet A and JP-5 are for aircraft engines, not suitable for shipboard diesels. The civilian No. 2 Diesel is common on land but isn’t the Navy’s standard for its diesel propulsion. So, the main fuel used for Diesel engines in this context is F-76.
