Normally I use Amsoil in my drivelines but am starting to look at some alternatives. My big hold up is finding a 75w140 GL5 for the rear diff on my 2011 1500. I... well my wife tows heavy with it and will be keeping the 140 weight. I know Amsoil, RP have good offerings but the Amsoil will need to be special ordered and the RP comes in at 24 bucks a quart at the nearest Cambodian Tire. I started looking at the Co-op (MP) gear oils. They have a 80w140 offering but I have one hold up... its poor point. Its rated at -21C according to its specs. The Amsoil on the other hand was somewhere around -40. [censored], even Amsoils straight weight racing oils have a lower pour point.
All other things aside the cold flow gets me. I regularly drive in sub zero temps and in many occasions tow when it is bloody frigid. Am I missing something or should I be changing my thought process. To me the cold flow is a very relevant sign of ones thermoplastic abilities.
