Oil Change Interval/frequency?

I have a 2015 900 Trail and want to know if anyone has good info on how often the oil should be changed. The manual says every 100 hours or 1000 miles after the break-in period.

Can these machines really go 100 hours safely on an oil change, or how often are you guys changing oil? I don’t want this to be a war about which brand of oil to use…
