I read that too and even bought a bottle of FrigiQuiet. Read the bottle and it says to use only as topping off oil with R12. Called the company to confirm they do not recommend it as the oil with R12. I went with mineral oil.

To clear up a few things:

1. I flushed the system to get rid of the PAG oil or whatever was used for the 134a.
2. On the vacuum, the gauge only showed 24 in Hg after pulling a vacuum for over an hour. The next day it was 22 in Hg, so said the gauge.

LarryB - I hear you on the 28 in HG, but I could never get it above 24 in HG - the pump just wouldn't pull it that low. And it's a pump the guy uses professionally in home heat pumps, so I don't think it has a problem. I am beginning to think the gauge could be innaccurate, something was said that there might be a problem with the low-side gauge. I pulled a vacuum on a reclaim jug in case I have to start over & the pump pulled it down to 30 in HG, so I don't know what to think. I do have 1 can of R-12 in the system I don't want to lose.

All - thanks for your help, I know I don't have it just right yet. Got more to do. I will he checking for leaks with the sensor when I get the gauges back. Also have access to some nitrogen & R-22 if I have to do some serious searching.

Will check back with results.
So are you saying the compressor was connected when you flushed the system?
Help me out guys, don't you have to drain the oil from the compressor?

The compressor should be taken off and flushed with the new oil being used to clean all the old oil out.

That's what I thought. I don't read anywhere in the thread that the OP removed the compressor. He just flushed.

On the other hand... IF he is dealing with a Delco R4 then at least he has NO OIL SUMP... so the amount of bad oil would be less than a normal type compressor... but I only deal with earlier models so I do not know what type compressor he has...
It is proper to hand flush all of them... just saying if that were overlooked for some reason an R4 would have less residual oil left over than most other designs.
