The Torco sythetic is great stuff. As I stated when defending myself for using sythetic gear oils earlier, I ran torco synthetic the longest and I put it in when I first began running my 3L. When I switched to MTL it was darn near two years.
When I opened up the transmission the fluid still looked and smelled like it did new with the addition of some basic wear items.
The thing that is amazing is I was running serious torque from nitrous to 3L and even some time with the turbo and the stock diff is still in perfect shape. I beat up on it pretty bad with high torque loads and well... you can see the picture.
I also never had a shift issue with it either although I don't live up north so I can't compare really cold weather shifts.
I ought to stop screwing around on the next fill and just go back to what I know works because of how long I used it and the photographic proof. Besides, it meets or exceeds GL4 specs.
Still, last time it ran me $11 a quart from BAT.
Maybe I can find it cheaper now.
OH, BTW. I see what you are saying about people suddenly changing the listing of their specs on their websites but I have a hard time believing that it would be just over our experiences here in our website. Granted, with as many hits a person will get from our site now searching for redline MTL, it is going to crop up a lot but I can't imagine it affecting the other companies.
I also am inclined to say that a bad batch of fluid is still kind of a long shot because just as you said earlier....you could run anything form ATF up to the spec'd gear oils and it wouldn't hurt anything. If it was a bad batch, someone had to drop something seriously different into the mix that day
Either way, I think it is just a combination of thicker fluid, lots of metal particles from wear, and non-existent or inadequate/ineffective flushing of the particles formed during break-in.
Obviously I'm not saying they are the same or have the same additives! I'm just reiterating what he had said.
