Is royal purple goid to run in our engines? I got a 91 NA auto

 

Its good but a bit expensive, but really when you are talking babying your motor, is there really anything you wouldn't do ? I put it in my trans and Differential on my 84 NA, was as smooth as butter, best shifting car I ever had, (still have ). If you can afford it they make a good product, there are a lot of excellent choices now days. You can get it in drums too, and save some.

 

friend of mine uses it. says be good.

 

I used it in my 350Z. Good stuff. I swear the car ran smoother and was more responsive.
