Is Valv Durablend Changing?

[ProfPS]

I was in the local Advance Auto Parts store and looked at the labels of Valvoline DuraBlend 5w20 and 5w30. On both labels listed CF ratings. I checked out the product spec's at the Valv website and they both are no longer CF rated -spec's date 5/2/06.

Are Valv and the oil co.'s changing their formulas -I noticed other co.'s 5w20's are not as abundant as in the past in many stores?

Is Valvoline DuraBlend's at the top of the qt oils on the market -last posting on Dura's was 12/05?

I have often wondered myself if MaxLife is DuraBlend with seal conditioners added.

Durablend was SL/CF, then it became SM and the CF rating was dropped, presumably because it wasn't robust enough under SM to meet the CF requirements.

My understanding is that Maxlife is more like All Climate with PAO added and seal conditioners.
