HD Syn3 make by Citgo , low quality oil not sure why HD went cheap . Better oil brands out there , I use Mobil 1 V Twin synthetic and Spectro synthetic in the tranny in my Softail CVO. Neutral easy to find and transmission quieter.

As ultrafxr has stated, Syn3 is a quality oil.
As you've stated you feel that because it's made by Citgo that it's not a high quality oil.
A little story from a few years back.
I used to get called into Union Carbide, now First Brands the maker of Prestone Antifreeze. Our equipment is used in their plants to finish making the bottles that they use to fill with Prestone antifreeze.
While there I noticed bottles with labels for Peak antifreeze, Chrysler antifreeze, Wal-Mart antifreeze, and the list went on. I was talking with the floor supervisor about all the different brands they fill and he said that each one is its own formulation. He said that if I wanted to buy the best, I should by Chrysler antifreeze. He said it had additives and such that were superior to even Prestone's formulation. The process was like this, once the production run was done and all the bottles were filled, they shut down and purge the lines of all product and then flush them afterwards to make sure they are clean of the previous product.
I've also been in oil bottle filling plants that use our equipment and their process is exactly the same. Most fillers provide oil for many different customers and brands. So just because it's made in a Citgo plant does NOT mean that it's Citgo's oil formulation. And I highly doubt that Citgo oil is a bad oil.
I used Syn3 for the first couple changes and then went to Amsoil. I had no issues with the Syn3, but SO many here have suggested other brands to be superior to the Syn3 in noise reduction and temp control. I personally have used Amsoil for decades and have always been impressed with it.
In my street rod that held 9 quarts of oil, I used Mobil 1 racing 20/50 and had great luck with it. In fact largely due to the use of the Mobil 1, I saved my crank and block. Now granted had I been using any other quality synthetic oil, I probably would have the same results, but in that case Mobil 1 was cheaper and easier to get locally for me, at least at that time. Today my HD dealer has Amsoil on their oil products shelf and it's readily available. But not to be out done, I switched again and this time I'm using Liqui-Moly full synthetic. My mind tells me there's less noise now, but honestly it's purely subjective and very hard to prove one way or the other. The only thing I'm sure of like ultrafxr said, I highly doubt I'll ever having any failures due to the oil I'm using.
