Hello all,
Just wondering what is best to use here-Manual states Gl-5 OR Gl-4, but ive heard and read that GL-5 is definately not good for these transmissions...Is this factual?
Also, i live in a remote location; NAPA(that is actually Ashland/Valvoline?) is the only cheaper brand closely located.Their info on bottle states, "API services Gl-3,Gl-4,Gl-5" Is this safe to use in my w-56 and transfer case?
Oh, and BTW- it is "80w-85w-90"(dont know, why triple viscosity...?), how does this differ from
75w-90 called for in the manual? Is 80w-90(80w-85w-90) an acceptable substitute? I know everyone uses Redline mt-90 or Mobil synthetic, but i cant afford those at this time...Thanks AGAIN!-Pagan (22re140k4x4w56)
