Gel test methods were modified to more precisely discern thickening tendencies in these oils. In order to determine the cause of the thickening of the 42a blend, studies were carried out on a series of blends, wherein systematic changes were made in concentrations of certain additives suspected of causing this thickening. It was found that three of the additives used in the above blend contributed to oil thickening. These were the fatty amine oleate, oleic acid and microcrystalline way. A combination consisting of lanolin and alcohol improved the gel-resistance of the oil blend. Corrosion resistance tests were carried out on these new blends to determine the effect of formulation changes upon this property. The humidity cabinet-ultraviolet light protection potential of this type of blend was lowered slightly by additive changes designed to improve the viscosity stability.
