ok, I have to come clean. I sell lubrication for a living. I work for the company its not a multi level thing like amsoil. We go throught extensive training on lubrication but I still leatn new things all the time. I can testify that during my time with the company using the industry standard tests that I have never had a grease beat or even perform as well as ours. The other 1000 people across the country that do my job will tell you the same thing. Im not trying to sell grease here believe me. I sell products in bulk so individuals are not in my market. Without being specific I can tell you that I personally have replaced most of the grease mentioned in this topic already and the customers love my product. Another thing one should look for in a product is IS9001 certification. My company has all types of grease lithium, calcium suphonate, aluminum complex, bentonite, as well as food grade. We sell aluminum complex the most. I can also say that lab results confirm that synthetic greases only perform to about 98% of what their natural ingredient counterparts can perform. Texas Refinery Company makes some quality grease along with Kendall, Canseco also has some decent stuff. Honestly as a rule of thumb, if you can find it on the shelf at your chain type parts house dont buy it. Also I'd run from Schaffer. This is some of what I have learned in the lube buisness. Im not trying to shove my products at anyone. If I can help with any questions I will try.
