I have not tried the nano-filters but have used their products for the last few years and the stuff flat out works. In the stang I will simply change the oil every six months, and according to lab tests this is too often, but that's ok with me. I have a buddy that switched from Mobil 1 to amsoil and he said he could tell a difference in the two. Kinda like using regular oil and the feeling you would get right after that oil change. Try it for yourself and make your own determination. Maybe start out by changing more often and extend that as your comfort level with the product grows.
