Hello all. I have a Husqvarna TS142 with 50 hours on it. I am religious on maintenance like engine oil changes and plugs filters and such. I am new to the Tuff Torq K46 axles and have been reading all kinds of stories on longevity with some doing just fine others failing. My yard is 3/4 acre and flat. The factory fill is a 10w30 std oil and TT suggests going to a 5w50 syn (winter/summer blend?). Therein lies my question.... I will never use the mower during winter months (below 50 degrees) so can I use a 10w50 syn instead of the 5w50 or go to a 15w50 syn? Looking for a high shear numbered oil.... like what's used in a motorcycle shared engine / trans. The trans works fine now and I know "if it ain't broke don't fix it" but don't want to be stuck in the middle if a hot summer and the trans begins to act up. Or do I have the heebie jeebies over a nothing burger? Recommendations please?
