With all due respect. From what I can find and have been trained on, #1 is Kerosene, not diesel fuel.
I do agree with many of the points you made, however there
is still a difference in the fuels. The differences between Kerosene, No.1, and No.2 are the hydrocarbon chains that are separated and concentrated during refining and the additives applied to each. K-1 Kerosene, No.1 diesel, and JP4 jet fuel are closely related to each other. No.1 and JP4 have higher allowable sulfur than K-1. No.1 is also a shorter hydrocarbon blend and has better solvent properties than No.2. Yes, No.2 does have a higher BTU rating and should produce more power and better mileage.
I was actually referring to European countries in my previous post, not countries like China. Thank you for clarifying
