I heard you need to change oil soon after using the concentrate plus, true?

What about the lowest potency ones? I got 6x12oz for $10 from Costco. Wondering if I should use the low concentration ones maybe once every other month? Or skip it and just stick to one plus before every oil change.

Thanks.
