I didn't  notice the mix up because both were the same price and the bottles 
are almost  identical.  I stopped at the local Chevy place and got a bottle of 
their  limited slip diff additive.  When home and put all of it in the  
diff--then and only then did i notice the MTL.
The MTL bottle says its  70W80 API GL-4 Gear oil.  I think I'm OK but would 
appreciate any  comments.  I really don't want the hassle of draining it all.  
Got  work to do to get ready for the Olympics.
Thanks in  advance.



Without having books at hand I would be sure the MTL GL-4 is designed for  
hypoid gears.  Front wheel drive transaxles use mostly (if not all) cross  cut 
or angle cut gears that don't have the same shear loads and requirements of  a 
hypoid and hypoid lubricant.
