to answer the original question in this thread:
from my experience Envirosafe works great,
I've used it for 3 yrs in my '87 420sel. I came to using it after spending way too much time and money trying to get my a/c to work satisfactorily with r134.
lost my a/c charge this spring, fixed the leak, and refilled with r290 just to try it while waiting for my e-s to be shipped. short term, it's effective and cheap.
but boy is this a loaded topic!
