Any of the solvents in the Keytone family will be a plasticizer meaning that it can destroy/dissolve plastics. It is a 150 octane rated fluid and is hot meaning that it vaporizes rapidly. There is no real science behind it to say that it works. B-12 Chemtool uses it a a carrier fluid. I would excerise caution in putting it in your tank as it also is a great paint remover.
