OK, so what did you really mean by your earlier statement?

Wouldn't you expect the higher tier oil to have better numbers. Yes I know there just numbers on paper, but still. For the lower tier oil to have a higher vi and a lower Noack makes me believe the PUP PDS is flawed. Could be wrong, wouldn't be the first time.

Ultra platinum has slightly higher Viscosity Index and slightly better MRV spec with a tradeoff in noack, but we cant compare two oils on pds alone, must wait for VOA/uoa to see how the add pack differs.

I think old PU was 167 VI and 7% NOACK. I wouldn't trade off a 80% increase in NOACK for a 4% increase in VI. I think SOPUS is crazy for releasing PUP with weaker specs than PPPP. How are people supposed to tell which is the better oil?

Since P4 will be available everywhere, and PUP will likely be a chase around game again, I'll take P4 since they are so close.

Thanks Rikstaker.
With that kind of pricing I might load up. Like I need any more oil.

Can't go wrong? Of course you can go wrong! You could spill it.
