Questions...do I need to clean the system (not just drain) of all the regular oil before putting in the synthetic? And, how often do you change the synthetic stuff?

I ended up going with Mobil 1 5W30 and a Napa gold filter. I was able to find the oil for about $4.20 which to me is not bad. I did flush the motor before changing. We'll see how it goes. Thanks for all the advice.
