Random AC question
When the manufacturing ban on R-12 went into effect, the price on existing stocks got pretty high. I was working for Pennzoil Products Company and we started selling this for $30 a can. I sold a lot for a few years. A couple places that specialized in auto AC work bought it by the pallet. After a few years, demand tapered, and we discontinued it. I found this picture on the web.
We sold this oil to use with it. This is in my garage.
