There is no definite answer on this because of all the variables.
Since you know how 80-90 works in it just get a bottle or two of 120wt and a bottle or two of ATF and see which one works best.
thanks for the reply i do notice when its cold it does not grind into second at all but once its warmed up it does at times maybe do to the oil getting thicker Or Thinner when warmed up?
