Does a vacuum pump or a refrigerant recovery machine also remove the oil from the system?
Thanks
Yes and no. Varying recovery machine designs, vehicle system designs, system volume, port locations, ambient temps, and many other factors; all come into play.
If the refrigerant is removed as liquid it will most probably have oils suspended in it. If it is removed as a gas, it will be leaving the oils behind in the system.
In a recent test on a Toyota Prius, which has the ports located at the highest point in the system, and only uses 1 lb. of refrigerant; we recovered (and recharged) this system 5 times with a fairly new Snap-On RRR machine and had no measurable oil removal occur.

Would there be any problem in adding 5 more ounces of oil just to be sure?
Thanks
