So. Many. Oil. Choices?

This is the only oil that I have been using for a little over 3-years now in my AV 4500 psi compressor.

Thanks to all for the input. I narrowed it down to the new Coltri 755, and a couple repackaged variants of Chemlube 800. I went with the Chemlube 800 variant. It a little more cost effective. I could only find the Coltri 755 in one liter, or likely would have tried that.

I talked to techs from both places for advice. The consensus was that newer triester based 800 was a 40W designed for harsher environment and would probably do better here in AZ and in compressors with “questionable” oiling systems. In the event the compressor runs hotter due to poor design or tolerance the 800 would undoubtedly lubricate better.
As an aside the newer Coltri 755 (vs the older 750) is also a triester based oil similar to the the Chemlube 800. There is no hard evidence, but is seems that the older (older being a relative term) diester based oils (Coltri 750, Chemlube 751/501) have detergents in them that when exposed to extreme temps may begin to break down and gum up. If changed a little more often this will be prevented. I read one review where the individual changed from Coltri 750 to the newer 755 and noticed the compressor instantly ran verifiably cooler and when doing the first oil change the oil was substantially less broken down. Again, I understand this is all anecdotal evidence, but the underlying theme seems to hold.
I know people have been using the “older” oils for years with very good results, I just made the personal decision to try out the newer oil and see how it goes. I’m always open to being proven wrong. It was a little more expensive, but if lasts just a little longer between changes and the compressor will in fact run cooler it’s a wash.
BTW neither tech tried to talk me into the more expensive oil. I listened to what they had to say and made the decision myself.
They were both the same price delivered so I went with the one where the tech was just a little bit more helpful (from Filtertech.com)

hunmm.......no wonder my compressors seem to run better with transmission oil than royal purple, I really didn’t like how thick it is.

Got the oil and compressor. Very happy with filtertechs.com. Had the oil from Florida to AZ in less than a week. During the week leading up to Christmas non the less! Really happy with the combo. Compressor runs quite, smooth, and cool. In all fairness I don’t have anything to compare it too, but this is doing exactly what I was looking for.
