I bought Super Lube 41150 Synthetic Grease (NLGI 2) for greasing ICON UCA bushing. Can I use this same grease for my propeller shaft. From what I am hearing there are 6 zirk fittings down there. I guess Synthetic ones are mostly for UCAs and Lithium ones are for propeller shafts. I heard people using Mobile 1 red grease for propeller shaft. Toyota only mentions to use NLGI 2. Did anyone use Super Lube 41150 for all 6 zerk fittings down there with success?
