i have an emax 25 and I'm approaching 150 hours, I've done the 50 hour service without issue but I noticed that the manual specs an oil change at 150 hours and the filter not until the 250 hour change. I then reviewed the procedures for the oil change and the footnote states to never change the oil without the filter change. I have to say I'm pretty disappointed in the service manual's many contradictions. Just curious if any of the experts have opinions on the issue, I've ordered a filter but at $30 shipped I'd rather not install a new filter if not necessary.
