Before yesterday's ride we decided to change the fluids in my new Ace. I believe the manual says you should change the engine oil after 25 hours and check the others. Mine had 8.2 hours on it. The oil was already pretty dark and a lot of metal flecks in it. The transmission fluid was changed too. That one looked like it needed it already as well. Just a head's up that it could be on the safe side to change the fluids a little earlier than recommended. Mine will get it again at 25 hours. Used Amsoil products for the fluid changes.
