I switched from PP to PYB after running it over 5 years and 125,000 miles and my truck seems quieter on conventional. Oil looks the same as synthetic after 3,000 miles so far on OCI and hasn't burnt a drop that I can tell. The new SN version is great and much cheaper. It worked well for me. Congrats to you.
how come you dont use highmiles version instead of regular version ? since it good or better then regular version ? and what weight did you use to quiet down the knock on start up ?
