Hi new to thee 4 stroke machines and was looking for some feedback as to how often the oil needs be changed on the 900 ace motor. I have a 2017 mxz tnt that was bought as a leftover in 2018 , it has around 900 miles on it from last year. I am going to have the first change done and all other services that should be done as a precaution ( it sat at the dealer for a year before I purchased it) and it should have the 300 mile services and such done . I am wanting to know if it is better to change the oil from here on at the beginning of the season or should go longer? I am averaging 1500 miles max a year right now .
