That said there is really no way to know exactly how much refrigerant is in there. There are 2 ways to find out.
1-Recover the refrigerant into a recycle container and weight it.
2-Flush out the system and replace with the proper amount of refrigerant & oil.
That last comment in bold scares me. When refrigerant leaks out, oil leaks out with it. Not only do you not know how much refrigerant is in there you don't know how much oil is in there either.
Get too low on the oil and your compressor WILL seize up.

Hmmm, thanks for the heads up. I don't wanna make things worse, thats for sure. I didn't look at the level closely when I posted earlier. But it does say low, full, alert on it, along with numbers which I assume is the pressure. It's an odd looking gauge. Kinda like an old style tire pressure gauge. Never the less, I think it may be best to remove all the old
R134 out and put in new. I'm not the best informed when it comes to a/c. But I thought the oil was mixed up in the can with the R134? Please pardon my ignorance. What is the proper amount of oil and refrigerent for an 85 300SD? Actually since this is a newer style compressor it may be listed on it somewhere?
