Yeah I don't know what it does but it seems to work. Hopefully it's a permanent solution but I have my doubts.A few hundred miles in and still not ticker tape machine under the hood!
At 3% of total capacity I can't imagine it's impacting viscosity to the point that it's making the difference.
I have had 2 bottles of Ceratec for about 4000+ miles and I have not experienced anything odd, yet. When I change the oil in another 1500-2000 miles, I will update here. So far, my engine has been super quiet expect the 2K rattle which is worst when cold but quiets down when up to operating temp but its still there.Has anyone had issues with Ceratec (no other additives) so far on the Coyote motors (crap settling out of suspension etc)?
