There are no detergents allowed in Aviation oil. and 2 cycle oil has none because of the metallic additives are not allowed to be burned. It's a EPA thing.

Please site your reference
Tom,
Sorry I should have been more clear. Its not uncommon for 2 cycle oils to have both dispersents and detergents. There are other detergents besides metallic ash, and the EPA does not control any of the metallic ash anyway.
My reference is my employer, and unfortunately as much as I would love to send you internal reports, I cannot.
