R-401B 22/152a/124 (61/11/28) A1 8 ALKYLBENZENE OR MO/AB MIX Lower temp. retrofit blend (boost to capacity >-20F) R-409A 22/124/142b (60/25/15) A1 12 MINERAL OIL or ALKYLBENZENE Retrofit blend; higher glide and discharge pressure/temp. Matter of opinion mixed answers. Do some research on refrigerant oils - PVE oil - supco 88 - magic oils & oil additive's - Most of the alternatives cost less. Some cost 1/3 of R-22 like for example R-407C. Reply.
