That was easy - I found it - I made the post below in July 2007 -

There's a Schaeffers vs. Amsoil thread going, but this is slightly off that topic, so I'll make a new thread -
While at my moms in Okla. City this last wkend I visited with a family friend - he has a large hay farm in S.W. Missouri, he owns his own plane, he has rebuilt engines, he's built custom houses for himself and his kids - very high talent man. So anyway, the topic strangely turns to oil - his face lights up as he tells me his Schaeffers story (btw, his name is Bob) -
Bob's son is the lube guy for a construction co. with construction sites throughout Kansas. His son does the lube work at every site - from large cranes to light equip. The company was using M1 products across the board. A Schaeffers rep comes along and shows a test (apparently on an application the constr. co. was already using) -
Schaeffers VERY significantly dropped the temp in a bearing compared to M1. The company started using Schaeffers on a limited basis at certain sites. Equipment operators began to report back positive results from the switch to Schaeffers - the company then switch all equipment at all sites to Schaeffers.
Bob hears all this from his son and starts running Sch. 50wt racing oil in his plane. His plane has gauges for the turbo temp and an independent guage for all six cylinders. Bob said he saw an immediate drop in temp averaging about 40deg (I forgot to ask what oil he was running before Sch.) He also said his six cylinders would run at widely varying temps (1200 to 1500 deg) - with Sch. they all pegged on exactly the same temp - he was quite plsed. Another knowlegable pilot flew with him and was surprised to see the turbo running at such a low temp. So Bob now has Schaeffers in everything - trucks, farm equip., etc.
He said Sch. grease was significantly outlasting his previous grease. He said Sch. grease had a stickiness to it but was still very slick.
Bob was extremely impressed with Schaeffers - and it was all on objective real data (not "it sounds better", "feels better", etc).
Last pt - a Schaeffer rep told Bob that within three OCIs he would see "no wear" in his vehicles. Sounds like the rep. perhaps drank a little kool-aide there, but perhaps Sch. if known for very low wear levels. I am presently ignorant in all things Schaeffers, but plan to push the learning curve before my next OCI.
