Thinking about using Amalie Blue Hi-Temp in the U-Joints of a `18 Toyota 4Runner. On paper this grease looks great. Anyone have any experience with it? Operating temp of -40F - 350F is what is looking good as I am concerned that Mystik JT6 High Temp is only good down to -10F. This is my all weather vehicle that in time will experience conditions like crazy cold in Michigan and traveling in the north during the winter. Will this outperform JT6 for long term use, or should I not worry about the few times I encounter temps below -10? I would love to use Mobil 1, but the reviews of turning to liquid dripping is disheartening. Also Valvoline Synpower looks great on paper with -40F-425F temp range and the 3% moly for the slide splines, but I have used this for years and always seems to be dry and clumpy. I would like to stay with a Lithium complex for both applications of the driveshafts.
