Whats the scoop with this stuff, good, bad...Anyone using??

 

i use it and like it

 

You have missed a big thread on this very same subject. For what it is worth, I just changed to the Pennzoil equivalent, and it still shifts butter smooth. I've noticed no difference coming from the GM syncomesh as Pennzoil supposedly makes both products. The Pennsoil is $4.99 at Autozone.

 

I use it. No complaints. Shifts great!
