There is no shortage of engine (or airplane, or computer, or ...)
experts who will tell you that you're doing it wrong, no matter what
you're doing. Screw that guy and his "advice". Keep flying as you
can. Use an oil with additives in it, plus you might consider using
CamGuard (http://www.aslcamguard.com/) which got a good review in Av
Consumer or Maintenance mag recently.
