syn or dyno in 0 turn hyd.

[big bubba]

just purchased a high end 0 turn mower. the hydraulics call for 20/50 engine oil w/250 hr change/filter intervals. am I ahead w/ a good synthetic, or will dyno do? would synthetic extend change intervals? apparently the oil heats up but probably no more than engine oil temp thanks bb

I believe most run a synthetic oil in the hydro systems.
