Re: Difference between no.1 and no.2 diesel?
Jet fuel (civillian) is just kerosene or #1 with a "light" spec. Jet fuel is handled more carefully, and goes through its own distribution channels to insure that it isn't contaminated with moisture, crud or other petroleum products. If any such contamination is found the entire lot gets condemned. Some guys who work at airports (and have the right contacts) fill their diesel vehicles with fuel deemed as not airworthy. Think about it, the same basic fuel that lit our homes in the 19th century power today's jetliners. It's the same stuff that powered the Saturn V rocket (with a little help from liquid oxygen) that put man on the moon.
You might not realize it but there is a certain amount of cross-contamination in the fuels you buy. Pipelines and tanker trucks handle gasoline and fuel oil as it comes along. Reasonable measures are taken to keep things seperated but there is bound to residue from one product that ends up in another. Just like there are federal standards which state exactly how many rat hairs and mouse turds are allowed in your corn flakes, there are specs on how much gasoline can be in fuel oil and vice versa.
