FAQs & Answers
- Why is diesel heavier than gasoline? Diesel is heavier than gasoline because it has a higher density, which results in more energy per gallon compared to gasoline.
- Does the higher density of diesel affect fuel economy? Yes, the higher density means diesel contains more energy, enabling diesel engines to often achieve better fuel economy than gasoline engines.
- Can I use diesel fuel in a gasoline engine? No, diesel fuel is not compatible with gasoline engines due to differences in fuel properties and engine design.
