Also, you might think about where you got your R-12 as well. It sounds like your R-12 might be salvaged R-12. If it was salvaged from a scrapped fridge, you might have mineral oil in your "canister" mixed with the R-12. Some salvage places don't bother to filter the captured R-12, so you get some mineral oil along with the refrigerant. Also, be sure that your R-12 is of good quality if it was reclaimed. It could have contaminants in it.
