Peter - I was under the impression that PAG is "universal" and can be used with either r12 or r134. The FSM calls for oil from sheet 362, which only has one oil listed (MB-brand) which I suspect is Denso ND-Oil 8, which is equivalent to PAG-46.
I've purchased several bottles of mineral oil over the years, and have yet to find one that lists the viscosity, so I'm hesitant to use a mineral oil that is not recommended by MB or Denso. I'm assuming that the 46 in PAG-46 is the viscosity. ------------- Max Charleston SC On Sun, Aug 11, 2019 at 2:47 PM Peter Frederick via Mercedes < [email protected]> wrote: > If you are using propane "test" refrigerant, you need the mineral oil, > anything with R134 needs the PAG or ester base oil -- PAG is too polar for > propane, and mineral oil isn't polar enough for R134a > > In either case you are risking a compressor failure due to lack of > lubrication, I'd make sure the oil is matched to the refrigerant. > > > _______________________________________ > http://www.okiebenz.com > > To search list archives http://www.okiebenz.com/archive/ > > To Unsubscribe or change delivery options go to: > http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com > > _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
