Hi Tyler,
I believe Bitron is still available as a friend swears by their diesel additive. I am also very skeptical of snake oils, but occasionally you find one that does exactly what it says on the bottle.
I hear good things about 'Mechanic in a Bottle' fuel additive, too.
Your comment above reminds me of a comment a senior oil analysis industry consultant once made; he likened the oil additive game to a tank full of sharks, with a thin layer of snake oil floating on top!
