Pennzoil

The same Penzoil shills, flooding BITOG with raving pro penzoil posts, are also here giving it undeserved high marks. They are over at BITOG, right now, whining about this site too.
Penzoil shills are all over the net pushing their product and advertising the "big penzoil 2fer sale".
Penzoil is at best not harmful. But right now it is highly over rated that's for sure. The wax buildup claim is crap though. You would surely be far better off with Castrol Syntec or Mobil1 Synthetic.
Penzoil is responsible for legitimising the labeling of Group III semi syn as "full synthetic", and don't even forgive them for that!
