Combines 90weight in gearboxesIJIJIJ

[combine_ken]

I run synthetic 50 weight oil in my 1680 final drives after having a inner bearing go out 2 years ago. These drives need all the help they can get. In transmission I run 75_80 gear oil, and Esso(Exxon) Hydral 56 in pto and rotor gear case.

I work at a CIH dealer and have been running 90w in all but 80 pto box for years.
