HVAC R22 mineral oil

Post by emsvitil »

Is the mineral oil for R12 the same as for R22?

I have some 525 viscosity mineral oil for R12, can it be used with R22?

I'm having trouble finding specs on what mineral oil to use for R22

No it is NOT. Automotive R12 uses viscosity 525 while R22 uses 150 depending upon the evap temperature. Goggle 3g, 4G, and 5G
