My stock compressor more or less seized, so i have a S6 replacement about to go in. Would you consider a flush mandatory when swapping compressors? My thought here is that there are decades of oils built up in the system that should be removed. Am i over thinking it?

Also, on http://gmcmotorhome.info/heat.html - It states:

Here are some bits of information that we learned at Osoyoos: (5/5/5)
1 AC technicians do not like to use 134, it is harmful to their health.
2 You do not need a vacuum pump to charge with Hydrocarbon refrigerants like DuraCool (Propane).
3 In fact they work better if you do not pull a vacuum.
4 Propane will mix with whatever you have in your system. There's nothing to change.
5 Recover the existing refrigerant (most of our systems are already empty).
6 Add 3 cans of DuraCool

I'm very curious about #3. The link no longer works. Does anyone know why it works better without pulling a vaccum?
