Big Dave –
I thought my car was low on Freon, but come to find out it had already been retrofitted to R-134a. So the compressor was pretty much full. It only held about a quarter of a can, and it seem to come out very slow. But it did help. Even just a quarter of a canyon made it below about 10°F colder. That’s why I’m only giving it four stars because I’m not for sure how good one full can would have been. Also my old hose busted so I lost the majority of the subzero hydrocarbon Freon. Oh well. It does seem to make a big difference. You may need to be Patient while using the stuff because it does have much thicker molecules. I believe that may also have been why it was so slow to come out of the can. But I will be buying it again when I need it.
