    Chev Trailblazer 2002: Could anyone give advice should I use oil additive for limited slip diff? Diff is charged with fully synthetic oil now and yes, the truck is driven in rather hot climate in UAE - if that makes any difference.Thanks!

    Full synthetic - should not be any need to use another additive. Normally using the recommended blend is plenty fine unless you are really tearing it up. The dealer sells a special limited slip additive which is very good. It just makes it extra slippery. If your worried about heat then you change the velocity to compensate. However, you have to take it easy when you start until the fluid warms up and flows freely. Kind of a double edge sword.
