The typical density of diesel fuel is about 0.832 kg/L to 0.85 kg/L at 15°C. According to industry standards like EN 590, diesel's density generally ranges from 0.820 to 0.845 kg/L at 15°C. The density can vary slightly depending on the diesel grade and source, but it usually falls within this range. This density is around 11.6% higher than that of ethanol-free gasoline and is important for engine performance and fuel quality assessment.
