Reduced additives are better for lubrication

Volume is volume, most stuff is soluble. The differentiation is so tiny that it is irrelevant.


I was poking around on the Pennzoil site when I stumbled across information that backs up the authors percentages. In Pennzoils motor oil fundamentals it states 75-85% base oil, 15-25% additives.

Anyone know how to post the pie chart.

Because it's a flash file you need to print the screen so it copies to memory, then paste it in a graphics program like paint, then edit what part you want. Save it and upload it to some webspace like Image-Shack or whatever and then insert the link to the image here.

Just go to the Pennzoil site.

Yes, but do Additives reduce, or increase, Lubrication as it flows past all the parts?

HH- Some engine parts do not need additives to be oiled correctly.
But some do, like the cam and valvetrain - and timing chains if you have one.
High localized pressure needs boundary layer protection, like ZDDP or Moly.

They can do either.

The dude is referring mainly to VII's, not AW/EP/detergent adds...

Most of the rest of what he said is just stupid, though.
