I was thinking about draining the factory 10W30 out of my John Deere X300 K46 trans axle in spring. I have a few bottles of GC left in my stash and believe this would be an excellent oil to put in there. The factory recommends using 5W50, but I believe the GC would work even better? (more shear stable from the heat) what do you all think? it only has around 16 hours on it now so...
