I tend to agree with the OP, that when looked at on the whole, Pennzoil can't be beat.
Their conventional oil almost always shows very low wear numbers, and last through long OCI's (seen a couple of 10K+ ones that were good)...same thing can be said for any of their products...
Also, their oil is very accessible - it's sold everywhere, so worry about finding it. Pennzoil, like Coke, has done a good job on that part of the marketing - when people 'think' of oil, the think of PYB.
