I didn't mention that because I didn't want to open yet another oil debate, but I have seen that as well on a lot of Pennzoil motors.
My Dad swore by it, but after seeing what I have three's just no way.
I even bought a Honda dresser motorcycle because I felt sorry for it when I saw a Pennzoil bottle sitting next to it when the guy said he just changed the oil.
I swapped it out for Castrol GTX before I even left with it.:D
