After re-reading this page it seems that @karl_h explanation in post #432 goes into detail to explain what @rcs9250 was saying in posts #423 and #427. This in response to similar cool down suggestions by @grackleblast in post #420 and #428. Thank you all for this important information.
So of course my head just goes spinning thinking this through.

I normally leave the the high pressure head drain open on my Bauer then later I close it to prevent outside air from entering. When running the pump open for a minute or two, do the cylinders ever really get cool enough that they are room temp? If there is enough of a difference in temp, moisture will develop ether on the outside or the inside. But only if there is water in the air. I guess doing something is better than nothing at all. Now what if after shutdown you let it cool off to room temp on its own, then run it with the valves open for 15 - 30 or so seconds to blow everything out before the cylinders get warm? 🤔

I left my infrared temp gun at work. I will bring home. I think if early enough tonight I will check to see what temps the heads are after cooling as well as at start up after about 30 seconds of run time with the valves open.

In southern CA like you are, I don't think you have much to worry about. Other than the rare long rains, your dewpoints are very low in general.
I'm not that worried but I also do not see running it a minute and a half enough to cool it. Tonight outside it was 71 degrees.

Running my bauer to 300 bar to top off my great white, the highest temp head (out of three heads) got to 180 degrees. After topping off I open the valve to the high pressure head and I let it run... 60, 90, seconds finally 3 mins. The hottest head was still at 130 degrees.

I think with the temperature difference if it were possible for the inside of the cylinders to drop out moisture to the cylinder walls it would still be able to.

Now if we were to wait until the compressor cools down to room temp and run it to push out the water..

Simulating a "after cool down" with the same 71 degrees, (prior to filling the tank) I open the valve and started the compressor. And measured the head temps. Everything stayed below 74 degrees up to 90 sec. I let it run and the center intake head rose to 84 (?) degrees. I think if I were to run the compressor to rid it of condensation I would wait until the unit cools then run it another minute.

Yes this is not a Alkin but it was in reference to a quote about Bauers. I would recommend you run this test yourself and make your own conclusions.

Pardon my ignorance, what's the shelf life on this type of oil - Seco Lube 500 as an alternative to Anderol 750? If I buy two gallons it may take me 2-3 years to use it all. With that said, is it ok to let the oil sit that long? I'm also taking into consideration how long it may have been sitting up in some warehouse. Here's where the MSDS can be downloaded and read.


I didn't see anythning about a shelflife unless I overlooked it.
 
I was hoping Humdinger might have knowledge on this question of expiration,,, as I have nothing
a google search gave me little info,,, that indicates a lack of problems with it

back in the power plant days we used Mobil DTE 27 in one of the turbine generators which after 25 yrs of my working there, I do not recall the huge tanks of DTE 27 ever being change,,, we did filter the crap out of it

if ya are worried just buy qts
 
Does everyone do a yearly oil change even if you don't hit the recommended hours?
As much as it pained me to discard oil with very few hours on the expensive oil, I did.
I didn’t want to be the guy to find out the hard way that I should have done it.
Many industries and products have recommended service cycles or recommendations that are total overkill or totally necessary. The aviation industry has very very strict requirements for maintenance for obvious reasons. I spent 15 years in the scuba industry where we had manufacturers mandated maintenance requirements for life support systems (diving regulators). About half to two thirds of the regulator owners followed the recommendation/requirement. That was their choice. I never heard of any failures. But as they say “You pays your money, and you takes your chances”.
