Should I go back to Moly grease?

Then I was lied to and it makes sense, they told me their rotary screw oil was group 4 and my Atlas Copco air compressor gelled up the oil in 60 hrs for a 8,000 hr oil and permanently clogged up a heat exchanger as if it was a group 3. What are your times?
Is the base oil acceptance back into the carrier base correct?

Maybe not lied to just provided a less detailed answer to paint a picture. The air compressor oil very likely is a group IV but they may not have enough group V to keep things in solution and prevent sludge and varnish formation. It would be like running an engine oil without a detergent package in a modern turbo charged engine. It may work for a while just not a long while.

The production times for greases vary widely considering batch size and exact makeup of product but you definitely aren’t making any grease in 45 minutes and no an Aluminum Complex doesn’t take days to make.

I’m not as well versed in Aluminum Complex as some but no thickener that I know of “accepts” oil back into it. Once the oil has bled out of a grease it’s not going back where it came from. Otherwise you’d hear of people “oiling” there aluminum complex greases instead of pumping in fresh grease.

they may be referring to the reversibility of the grease??,making a aluminum complex grease does take a bit longer to manufacture am told. not sure of the time factor of the blending/heating and cooling process.may vary from the manufacturing/brand

Just an FYI, but Lucas has switched their red grease from lithium complex to calcium sulphanate. Not a big deal as the calcium type of compatible with lithium complex. Since that plant burned down, lithium materials have apparently been hard to obtain.

I wouldn't consider calcium a downgrade either, but it's good to know what you're getting.
