Dude, at 17 hours you shouldn't even see the CFI unless you're getting ready to jump in the plane, no more hand holding for administrative stuff at that point! CFI is only supposed to log hobbs time and any ground lesson, THATS IT. Supervising you on preflight or fueling doesn't count! And what are you doing fueling the plane anyways, don't you have ramp rats at your airport?

If you are a good pilot, you should be ready to solo by your 8-10 hour mark. At 17 you should be into cross-countries. From my experience if you have ANY doubts about your cfi, that's the time you should dump them, a good cfi doesn't give you any doubts. Also do not get the most popular CFI at the school, doesn't matter if they have a 100% pass rate, it's more important that you have somebody that's avialiable. My first CFI ever was basically the chief CFI of the school I dumped his ass because he was never available.
