What is the micron size of a gasoline molecule?

Answer 1

Engine performance and efficiency is measured not only on how it was constructed and the materials used, but also on the characteristics of the fuel it will use. For gasoline fed engines, the smaller the molecules, the better the power is produced during combustion. Different Oil companies have their own blends for gasoline and the particle sizes will range from 30 to 100 microns depending on the blend. Engine designers have introduced advanced injection systems that further break down the gasoline particles up 10 microns as they are fed into the combustion chamber.

Answer 2

The average molecular size of gasoline molecules is around 4-7 angstroms, which is equivalent to 0.4-0.7 nanometers in size. This is much smaller than the typical micron size range, which is one million times larger. So, gasoline molecules are on the nanometer scale, not micron.
