Point well taken, but what about the possibility that an oil produces better results in some applications even if another oil " uses a better additive package and a better VI improver than Chevron or Mobil"...?

This happens on a regular basis. Some oils perform better in certain engines under certain applications. I am a big supporter of Pennzoil and Shell products and they have always worked above my expectations in my applications. If I had an application where those oils did not perform for me, I would find an oil that did.

Just wish Pennzoil hadn't dropped Performax 100. Give me that in a 0W40 and I'd forget the rest.

sprintman, I agree with you 100%. That was a great oil and the marketing department and bean counters was it's demise.
