My two cents: With that engine application, if I were looking for 10k+ OCI, I'd go with the PU in 5W-20. If I were looking to save some money and go with a 7.5k-10k OCI, I'd go with the PP 0W-20 or QSUD 0W-20.
PP 0W20 or PU 5W20

Can I up the ante and get .05 cents worth?
Why not stay at the same oil wt.? Why go to a 0W20?

*raised to $0.07 now
[I'm no expert and this is really just from what I've gathered over the years reading on here] The 0W should reach engine parts sooner than a given 5W, but not necessarily [depending on the brand and what end of the cSt margin it's on]. I can't remember exactly between PU 5W-20 and QSUD/PP 0W-20 [and comparatively between QSUD/PP 5W-20 and 0W-20] but I think they are fairly close in terms of cold-pump and cold-flow. In reality, I think anything above 40 degrees it's not that much of a difference.

Really? That's very interesting. I have done a lot of reading and research on PP and never saw an article stating that.
Are you saying it's a blend like Castrol SynBlend and MC?
Maybe not definitive but compare the MSDS's from;
http://www.epc.shell.com/
under "2. COMPOSITION/INFORMATION ON INGREDIENTS"
PP 0W20 is worded
"Synthetic base oil and additives.
Highly refined mineral oil.
The highly refined mineral oil contains w) DMSO-extract, according to IP346."
PU 0W20 has the below additional statement that leads me to conclude PP includes other than Grp III, of unknown percent.
"The highly refined mineral oil is only present as additive diluent."
I missed earlier a listing for Pzl Platinum (apparently a different product from PP) that is worded same as PU 5Wxx.

My 10 cents worth...........is that they are both very good oils. Use PU if you can find it and PP if not.
BTW - the higher NOACK of PU leads me to believe that it uses a better / higher-quality basestock than PP.
PU has a 150ppm more Boron than PP and a more moly too.

We have to be cautious when using an MSDS as an ingredient list, since that isn't quite accurate. In any case, it would not surprise me in the least if PP were a blend of several types of base stocks, like M1 and probably every other synthetic out there.
