I have read posts here for several years, but this is my first post. I am looking at several different oils marketed for use on firearms. Many new products purport to be synthetic oils, vegetable based, or PAOs. But I see that some still use conventional oils. I would like to know what is the difference between Distillates (petroleum), hydrotreated light naphthenic CAS number: 64742-53-6, and Distillates (petroleum), hydrotreated heavy paraffinic 64742-54-7? Particularly, Hoppes brand lubricating oil is the heavy paraffinic, and Hoppes brand elite gun oil is a blend mostly made of light napthenic. Are there any fundamental differences like pour point, flash point, basic slipperiness, evaporation, or other characteristics?
