The kind of oil usec in the AC systems on my Vans has come into question.
In looking thru the BENTLEY,  Ifind no reference to AC oil at all.  At
ADVANCE AUTO PARTS their parts and service computer for the Vanagon shows
so many ounces of PAG OIL - or - so many ounces of mineral oil. Can anyone
quote me a rererence as to what it is supposed to be and what quantity???

Next question: when flushing the system, is it lines only or does the flush
material also get washed through the condenser and evaporator???
I have a new receiver/drier to put on after the flush.
