Sounds like it would be better to put this filter on halfway through an oil change. It dissolves too quickly. When oil is new, you don't need the fresh additive kick, only when its nearing the end of a long oil change interval. New rule: Only change oil filters halfway thru an oil change interval, never at the beginning, when using this thing.
