Correct amount of freon

Correct amount of freon
Only takes a few oz. Just because some leaked out of the compressor doesn't mean there isn't any left in the system, the condenser, evaporator, compressor and drier all holds some oil. Most oil specs are for a complete system overhaul. 4-5 oz tops in the compressor and you'll be golden, can't remember if it's low side or high side you pour it in... I'm thinking it's the high side. As for Mitchell and alldata; it was nice having access to all of that stuff for the two years I was at college. I just can't see paying full license prices when It won't be "paying for itself" I.e I'm not employed by myself. Very valuable resource tho... Print out as much as you possibly can! Assemble your own shop manual, chilton or Haynes will never be able to compare

My system was converted to 134a. Is there any way to tell what kind of oil was used? I guess it probably was either Ester or PAG oil but how do I identify between the two types of oils? I'm going to convert it back to the old type of refrigerant since I have a huge source of it.
I heard that our systems take around 9 oz of oil but just wanted to confirm. Since I don't know what kind of oil was used, it would be better to get rid of all the new oil and start over. Could I get it all out by blowing all the lines out?

Nope, you'd have to flush the condenser, evaporator and replace the receiver/drier. They probably used PAG in the retrofit. Huge supply of R-12 eh? Lol that sounds sketchy... Becareful who you say that around especially if you don't have your certifications. I think you aren't supposed to have more than 5 pounds in your possession.... It's been awhile since I had my A/C training and my MACS certification is long expired

I think it is 5lbs. I dont remember the amount either and it was just last year for me. I know it varies by state as well. Here in wisconsin you can not have anything. R134 or R12 with out a license. R12 is straight up illegal to buy even with it. Thats why its important to have friends out of state.
