I just realized that Pennzoil offers a warrany if you exclusively use (and document) their products. Here's what I thought was curious: For Platinum and below, the warranty is 300K miles or 10 years. For Ultra it is 500K miles or 15 years.
I have never kept a car past 200K, but most people on this page know that with a reasonably well built and well maintained car, 100K+ is pretty easy and not a remarkable feat like it used to be. As a side note, I had 2 different model year V-8 Mercury Cougars XR-7s go past 180K miles prior to me selling them and they were in perfect mechanical condition when sold. They received regular bulk dino oil and filter changes every 4K miles from whatever quick-lube place I lived close to at the time. I would have guessed that the Platimum and Ultra warranty would be in the 500K category, and all other Pennzoil products in the 200K - 300K range. I wonder what about Ultra makes it worth an additional 200K miles and 5 years (in Pennzoil's eyes) over the rest of the Pennzoil portfolio?
