Vegetable oil alkyl amide?

[G-MAN]

What the heck is "vegetable oil alkyl amide"? The picture of the back of the Saab 0w30 oil posted over in the VOA shows some of the ingredients and this is one of them. (I'm assuming this is some sort of ester.)

An ester is the reaction product of an acid and an alcohol. An amide is the reaction product of an acid and an amine. The amine has a NH2 group where the alcohol has an OH group. The alkyl amine simply is an unspecified chain length amine. The vegetable oil likely refers to an unsaturated C18 fatty acid from a vegetable oil. Your vegetable and animal oils are mostly 3 C18 fatty acids esterified with glycerin.

The organic alkylamines are usually compounded with an ester, be it synthetic or natural, to provide Surfactant, Antioxidant, and Anticorrosion agents for fully formulated oils.

Usually provided from the additives suppliers as a very thick and slick fluid, light tan or light amber in color. Mostly used as an additive in polester-based synthetic lubricants.

The surfactant in Schaeffer's #132 is very similar.
