Considering Pennzoil will warranty your engine for 300k on this oil if you start using by 75k total vehicle miles, and the fact that you can frequently get $10 rebates on 5qt jugs, I'm going to go out on a very thick limb and say you're welcome to your opinion but in the absence of hard data, that your statement is worth only what I paid to read it, or less.
As bbhero points out, and has been discussed quite extensively lately on the board, HTHS is much more relevant than KV100 when it comes to protection and wear. It's also one reason I'm looking at running Redline 5W20 in my Subaru since the HTHS of 3.2 is well in to the same realm as all the other 30wts I've run, and AAMOF it's actually higher than the Amsoil SS 10W30 (3.1) that's currently in my vehicle. However, the Redline 5W20 KV100 is just over 2 full points lower than the Amsoil, I'm expecting a reduction in pumping losses, and quicker lubrication on startup while not losing any protection in the bottom end.
OP, the PP 5W30 is fine for any vehicle that calls for the 5W30 and the specs it meets; if you're looking for a really thick 5W30 and prefer the yellow bottle and easy availability at WM, look at the PP Euro L 5W30. My VOA showed a KV100 of 12.38, which is at the very upper end of the 30wt scale.
Has anyone been able to use the warranty? Other oil companies have a warranty also.
