Its the same functional product.
I inquired with Dr. G of Optimum and his direct answer with me over the phone was that they were the same base product but the new OLP was thicker to spread easier on leather/vinyl surfaces and the fragrance has changed nominally.
I've used both; they both perform the same save for the very minor variance in application "feel".
You got the right stuff, you'll still love it and the new OLP formula is a bit easier to apply overall.
