The lab I refer to is ASTM, gov't regulated. I agree testimonials are not the end all. You only care about how can it perform in your equipment and save you money.
I have to fall back to cost advantage. If there is a lubricant that can perform to our level, it is going to be more expensive. If the lubricant competes on price, it cant perform to our level resulting in higher grease consumption, higher lubricant related failure, more down time, higher repair cost.
Google "Lithium Complex Grease". The info given will confirm the following.
Point 1: Aluminum complex greases are water proof, period. They will not emulsify with water, they will not wash-out. This single fact will reduce your grease consumption by 2 or 3 times. If it takes 3 tubes of your grease to last as long as 1 tube of Schaeffer grease, which one cost less to use? Water is heavier than oil. When a grease emulsifies, the water displaces the lubricating oil leaving only the thickening agent to lubricate the bearing. This causes excessive and premature wear.
Point 2: Schaeffer greases contain a solid lubricating package that include MoS2. Cat studies have been so complete, they require, in heavy equipment5% Moly for greases used in Pins and Bushings and 3% Moly in most everything else. Moly has been proven, through independant studies, to reduce the coefficient of friction as much as 75%. I've had people tell me they haven't had a lubricant related failure since switching to Schaeffers. If you have 1 tractor we aren't talking a lot money. But imagine a large farming operation or a construction company, now were talking thousands of dollars in related costs.
There is so much information I have left out. You would be shocked at the number of mechanics and maintenance professionals I have talked to that don't know how a grease is built or how it functions. These are only two of the benefits using Schaeffers grease brings to the table in realizing a cost advantage.
Anyone is welcome to PM me if you want to know more.
