Diesel Oil vs. Gas Oil: Know the Difference
By Shumaila Saeed || Published on January 7, 2024
Diesel oil is a heavy-duty fuel for engines with high compression ratios, while gas oil, often heating oil, is lighter and used in heating systems and older diesel engines.
Key Differences
Diesel oil, primarily used in diesel engines, is designed for vehicles requiring high torque and efficiency. Gas oil, in contrast, is often utilized in heating systems and older diesel engines, offering a lighter fuel option.
