On the fluid: I was confusing my reading on silicone DOT 5 vs. a synthetic DOT 3/4 fluid such as the Valvoline fluid. Guess they both might be considered "synthetic".
Also did a little internet research on the Mityvac's and similar and of course if your not careful you get what you pay for doing internet research, but certainly there are places such as here where folks do try to give the straight scoop. General consensus is that some folks did have problems introducing air back into the lines with a Mityvac. My experience has been pretty good however. I think the key with the Mityvac is to go very slowly when you crack the valve to minimize the possibility (um.. prevent) any air seepage back through the threads. The Mityvac has been a good thing for me especially when an immediate helper isn’t around to help with the traditional way. In the past I have had my wife, daughter, friends and neighbors help however.
I do appreciate all this stuff because while I’ve been working on cars all my life, and prefer to do all the major and minor stuff myself, but the extent my experience will never compare to someone who is actually actively involved in the industry.
