Uhh... I have a bad feeling about this. I have a really hard time believing that they just wanted to add more ZDDP and were willing to go back a spec to do it. Is there even a market for that, outside this forum?
Nobody else thinks WalMart wanted it to be cheaper, and the only way Warren would do it was to dumb down the specs to SL levels?
I'd be interested to see a VOA, but there are just too many other known good oils at about the same price.
