Getting the rear diff fluid changed out tomorrow. The shop stocks the Amsoil Slip Lock additive -- is this stuff even worth it for our cars?

the shop should have access to amsoil svg-7590 gear lube, which does not require you to use additive. if you go to amsoil web site, look at the study of automotive gear lubes. very informative... it shows the svg-7590 has superior test results than the redline. just my .02
