After reading all the reviews on here I decided to order some and have my dealer put some in when replacing my lower control arms. I defiantly noticed a difference. The gear engagement is a lot smoother. I have only put about 30 miles on the car since adding this, I have a 13 build so I guess I have 2 bottles in the car but obviously this stuff does not last long since I only have 4000 miles in 1 year. Time will tell if this will last for awhile but for now I am happy.
