Do ships use diesel

Yes, many ships use diesel as a fuel source, particularly those with diesel engines. These engines are commonly found in smaller vessels, such as ferries and cargo ships. Larger vessels, like container ships and tankers, often use heavy fuel oil, which is a more economical option for long-distance travel, but some modern ships are increasingly adopting cleaner alternatives, including liquefied natural gas (LNG). Overall, diesel remains a prevalent fuel choice in the maritime industry.
