Yeah Kurt, only tool you'll need to set any oil change reminder is the owners manual or an internet search. ( Unless your driving a BMW )
As far as a scan tool I do prefer the OTC as that is what I began with many moons ago and understand. But a scan tool with any capabilities is gonna set ya back a bunch of dollar bills. And then theres the software options and updates. I just gave over 9 bills to get me from 2008 up to 2011 for USA & Asian.
