This is UOA number two on the rear differential of my 2006 Toyota Tundra Double Cab 4WD with Limited Slip Differential. This UOA had 8 ounces of Amsoil Slip-Lok additive in it, which was probably too much, but it didn't seem to cause any problem. I used only 4 ounces with the change I did after the current sample was drawn. I am really pleased with this UOA - I wished the front Diff and Transfer Case looked this good. Unused, Virgin SVG tested out at a TAN level of 4.3. Comments?
