How Much Oil for R12 AC System

Roger3 on Thu August 23, 2012 4:37 PM User is offline

Year: 1967
Make: Chevy
Model: Camaro
Engine Size: 350
Refrigerant Type: R12
Ambient Temp: 70
Country of Origin: United States

How much mineral oil does my 67 camaro AC system need?

It's the stock AC system. I took it all apart and flushed all components (compressor, evaporator, and condensor). Installing new drier, new hoses, and o-rings.

Going back with R12.

I just bought the car and the AC would blow but not very hard, and barely cool. I took the AC system all apart to flush it, clean the evaporator core box (it was full of leaves, acorns, etc), change all hoses and o-rings, replace gaskets and seals in AC box and heater box. Just putting it back together. I did this to my 71 corvette and it blows good and cold, hoping for same success with this one.

Oil capacities back then were pretty much standard with the A-6 compressor: 10.5 ounces of 525 mineral oil. Correct factory refrigerant charge for your Camaro is 3 lbs of R-12.

Sounds like you're doing this right, so their shouldn't be any problems. Cleaning the evaporate case is a great idea.
