It has been proposed already to improve the resistance of mineral lubricating oils against deterioration, by adding certain amines. While in the main productive of advantageous results, a diflleulty arises in that under some circumstances of usage which is quite drastic, particularly by high temperature exposure, such products do not last as long as is desirable. I have found however that particularly durable lubricants maybe prepared, capable of standing up under various drastic usage conditions.
To the accomplishment of the foregoing and I related ends, the invention, then comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the vari ous ways in which the principle of the invention may be employed.
Taking an oil as a desired base, as, for instance a mineral oil the viscosity of which may be as desired, I incorporate therewith one or more compounds of detail more particularly referred to hereinafter. Thus, a petroleum stock for example of viscosity of 47 to 200 Saybolt Universal ,at 210 F. may be employed, and with this incorporated a small amount of an aryl amine compound of a fatty acid radical of at least ten carbon atoms or a naphthenic acid, and especially a phenylethylenediamine compound of the acid.
