I thought it was all smoke signals until I just recently swapped my engine oil to Schaeffers. The engine was noticeably more quiet and the oil temps have dropped.
Schaeffers "All Trans Supreme"
- Thread starter DBUSHLB7
- Start date
As mentioned, I have used Schaeffer's All Trans Supreme in my transmission builds for over 5 years now. It's not an optional upgrade, it is what comes in every build. I have not had any problems with it when used with fresh Alto Red Eagle, GMax, or Raybestos clutches. I also run their 80-140 gear oil in my diffs and their Moly Bond 15W40 engine oil in my truck.
Again though beware that the 5-40 9000 series will exhibit chemical leaching from the copper oil cooler for the first few changes if you go that route. It won't hurt anything, but any oil analysis will have a copper spike that could hide bronze wear.
I haven't personally tested if the 7000 series 15-40 does it or not, but it still contains a decent blend of poly alpha olefins so I suspect it would.
Not a huge drawback and other than that, best lubricants you can find.

It definitely has a unique smell to it as well. Well, coming from someone who has ran stinky Rotella his whole life lol.
With the Moly-bond X-200 I'm not going for long oil life or extended changes, and with a big external oil cooler with it's own fan and a temp gauge I'm not so concerned about the hot temps that synthetics can hold up to better; I am using it because I feel it will hold up the best to the extreme pressure abuse it will see in high hp applications.
You may be right to not choose synthetic, depending how often you change oil, what climate you live in, and what bearing tolerances you run. Synthetic is actually a Marketing term more than a description of the oil anyways. Most "synthetic" oils are far from synthesized PAO Basestocks like Customers seem to believe. Anyways heres my laymans description of why i believe people should run Schaeffers.
The benefit is actually not that it holds up better or worse as a lubricating film, it's more that its already prepared to fail before you put it in!
The measure of oil film integrity in extreme conditions in terms of "will my oil still hold a film in my bearings?" Is probably best guessed by comparing the HTHS viscosities and shear stability after testing. In that sense almost nothing beats a true ester of glycol base stock(not schaeffers). Where Schaeffers really shines is their "anti-wear additive", which is more or less microscopic softer sacrificial metal bits suspended in the oil that are there to take the hit and get squished when your bearings press through the oil film and would make contact.
Schaeffers pioneered the use of molybdenum as a consumable anti-wear additive, and they still use it better than anyone. Add in that they also utilize antimony in the same way (i havent seen another oil with moly and antimony) and have excellent detergency without being solvent and their base stocks are incredibly shear resistant, and you basically have the best real world performance possible for ~$15-25 a gallon depending which blend you want.
I'm not employed by them or affiliated, I have to pick mine up at a distributor like anyone else. I have a fancy schmancy college degree in this stuff, and I firmly believe this is a great product from one of the best companies in business. They spend $0 on advertising because they can convince engineers and farmers to buy into their products just based on their quality and reasonable cost.
Try some yourself and run used oil analysis if you don't believe me.
