Yes Sir I did! I watched the series he did on diff covers, and he did a great job compiling data. He's also a great salesman and managed to incorporate his own product into the presentation. I think more products should be presented like the Banks Diff Cover, backed by real data and evidence.
Amsoil might be the only exception, since they talk about Trimmer Moly on their own blog. Well, Amsoil has industrial railways going through their factory and they had a very long and fruitful relationship with ExxonMobil, Lubrizol, and probably Shell. They're an oil blender that serve a niche market and probably a microscopic fraction of farmers and truckers and the US and Canada. They're not really competition for the big guys, but more like customers, lol. So I don't see a problem for Amsoil getting their hands on the best additives to put into their products.
Thank you so much for your advice. You're absolutely right. I don't tow much. The last time I towed anything heavy was a 1200 LBS truck transmission in a 900 LBS trailer when I took it 100 miles down the road to have it rebuilt, and the next day back to put it back in my dad's truck along with a new clutch, hehe. I'll save my money and get the transmission pan along with 7 quarts of Lifeguard 8 fluid. I need to do a transmission oil change anyway.
This would be the ZF approve diff fluid for the RAM 1500 rear end:

These are the specs for Castrol Syntrax 75W-140 Limites Slip gear oil:

Compare it to Red Line Oil and AMSOIL Sever Gear and specs-wise it's a heck of a lot better than those. Just the pour point is mind-blowing, along with the Flash Point. Looking at the MSDS it contains a good amount of PAO.
