I know I'm probably way overthinking this, but I'm trying to decide on one grease to use for a couple different purposes. The main purpose is for trailer wheel bearings. I have both a boat and a utility type trailer for towing a side by side. The majority of towing of the utility trailer is at highway speeds a couple hundred miles at a time. I guess having a failure, and having the wheel w/ hub pass you going 65+ will make you overthink it a bit. (The failure was not due to type of grease) I also use the grease gun to lube various parts on the SxS like suspension bushings etc. Currently have "Green Grease" in the gun. Looking at that, Redline CV-2, or something from Schaeffer or Amsoil. I used to use M1, but I keep the grease gun in the shed, and as noted, M1 leaks a lot.
