Gasoline (Petrol) vs Diesel: Which one is better? A Beginners Guide

The video explores the differences between gasoline and diesel, focusing on their characteristics, emissions, engine construction, and applications. It highlights the ongoing reliance on fossil fuels despite the rise of electric mobility. Gasoline and diesel have similar calorific values but differ in density and volatility, affecting their energy output and emissions. The video also discusses engine construction, performance, and the cost implications of using each fuel type. Ultimately, the choice between gasoline and diesel depends on specific needs, as both have unique advantages and disadvantages.

What is the primary reason for the ongoing reliance on gasoline and diesel despite the availability of alternative fuels?
