What if you use a Fram filter along with your Pennzoil or Quaker State oil?
Breaks the fourth seal of Revelation and unleashes death upon the world. Or so I've been told.
LOL!
I know some guys from college that work at SouthWest Research Institute in San Antonio and they are telling me Pennzoil is a top quality oil now. They test oils at SWRI. Another friend used to work at the Mobil oil lab in Dallas and he told me not to use 10W40 as it has a lot of viscosity improvers (VI) in them and they break down to 10W30 pretty quickly.
