There was a brief period where they reduced it slightly; but Valvoline
Racing has always had ZDDP in it.  It's not entirely clear to me that 900
PPM is worse than 1100 PPM as long as you change oil frequently; more just
lets you run the oil longer before it is depleted.  But the consumer
reaction was apparently enough to convince them to put it back up.
