laugh all you want but I have found the quietest oil yet. Valvoline dyno straight 50 wt. yep I have tried them all in the last 4 years and 70,000 miles and if I had not heard it I would dismiss it, but it is oh so quiet that I had to post even tho I was reluctant. oil temps have stayed the same, mpg the same, everything the same but no more tick tick tick. amsoil, mobil 1 20-50, rotella (a distant 2nd quiest) harley 20-50 syn and dyno etc.
