PYB (API SN) vs PYB (API SM)

[HangerHarley]

Which PYB is better? And how does it compare to RLI, Research Laboratories, Inc. (a ringer of sorts, instead of, oh, Royal Purple?)

PYB is pretty dang good. Would you choose yours in SN flavor, of SM? The SN is supposed to have more Moly. SM is going to be phased out and replaced with SN, so the SN has significant advantages over its formulation?

And then you have the Vegetable Oil oil, and the Purple oil.

Moly=good.
Therefore my pick.

 

[webfors]

Yeah, I'll choose SN. Progress is good, especially at Shell

I'm hoping the SN Formula Shell gets a dose of Moly too. In the SM flavor it was one of the highest in PQIA's tests and my Subaru seems to like it.

But if PYB has gotten a Moly boost, my Subaru might like it better now too...hmmm.

Which pyb is SN? I have a brand new jug of GF5 pyb 10W40 and it`s SM. What`s the difference?

 

[HangerHarley]

Newer formulation. Its at Wal-Mart too

I went in two months ago, and they were blowing out the old misshapen bottles.

 

[Scienceman]

Myabe they will sell the older stuff cheap.

Last week I purchased a 5 qt jug at Wall Mart and it was an SM oil that already met the SN rating as another post brought up.

I am wrong it was GF5 Forgive me.

At my WalMart, they have thrown in the 5w30 SN with all the older SM oils....and the SN is also $12 a 5 quart jug.
