Making the oil "thinner" does not make it inferior.No offense, but there was a time where Pennzoil Platinum and Pennzoil Ultra seemed like the best oils out there, but IMO they have seemed to have cheapened there oils.
The HTHS is a better determining factor than KV. I think you'll find that most of the SP/GF-6 5W-30's are 3.0-3.2 anyway; in other words, no significant difference.I agree with you, @The Critic. But it also does reduce the amount of applications I'd consider it for. Some vehicles seem more suited for a thicker 30 grade, while others (especially TGDI vehicles that call for a 20 grade) would be more open to this thinner 30 grade.
Correct. HT/HS is the indicator.The HTHS is a better determining factor than KV. I think you'll find that most of the SP/GF-6 5W-30's are 3.0-3.2 anyway; in other words, no significant difference.
Good point. I was thinking along the lines of a known fuel diluter that you want to finish in the 20 grade range at the end of its OCI. If you start too thick maybe it ends up >9.2. Or is that pretty insignificant too?The HTHS is a better determining factor than KV.

Not sure, but my guess.....it is immaterial.Good point. I was thinking along the lines of a known fuel diluter that you want to finish in the 20 grade range at the end of its OCI. If you start too thick maybe it ends up >9.2. Or is that pretty insignificant too?

Is there really proof of this? I have heard many repeat this, but no proof. Seems to work well in the cars and trucks that I use it in.No offense, but there was a time where Pennzoil Platinum and Pennzoil Ultra seemed like the best oils out there, but IMO they have seemed to have cheapened there oils.

What specs are you referring to?Sometimes an oil comes out and the specs via the SDS look great and then a year or two later the oil specs do not look that good. Meaning that the formulation has changed.
Safety Data Sheet and VOA's on various Pennzoil Platinum, Pennzoil Ultra, and now Pennzoil Ultra Platinum. Every oil that has been talked about on this Forum has had its ups and downs.What specs are you referring to?
I asked for proof that Pennzoil had cheapened their oils, and you can’t seem to provide any. It’s ok, it gets repeated a lot on here.Safety Data Sheet and VOA's on various Pennzoil Platinum, Pennzoil Ultra, and now Pennzoil Ultra Platinum.

I see what you are saying, maybe I should have worded it different, I once thought Pennzoil Platinum and Pennzoil Ultra were the best oils out there. Then I read what I read here, and I was turned onto a different oil and I like that oil better.I asked for proof that Pennzoil had cheapened their oils, and you can’t seem to provide any.

I’m really not agreeing or disagreeing, just trying to understand why people think that about Pennzoil. I use it often and have no issues, but I am not cornered to any one brand either.I see what you are saying, maybe I should have worded it different, I once thought Pennzoil Platinum and Pennzoil Ultra were the best oils out there.

drtyler, 1 thing we must all do is be open minded, this Forum is here to discuss everything about motor oils and sometimes we do not agree on things here.

I have asked others who state similar about Pennzoil, and nobody will provide any sort of answer. Its like a myth began, and folks ran with it. Happens a lot, unfortunately.
