Abstract
Benzo[b]perhydroheterocyclic arylamine compounds have shown to be particularly useful as stabilizers. The compounds may serve as antioxidants, antiozoants, heat stabilizers and ultraviolet light stabilizers and such compounds are oil soluble, thus particularly suited for use as an antioxidant in a lubricating oil composition.
