are the new winglets on the 700s used more for longer flights to save fuel

I prefer the old winglets and will connect if needed do they have software for this

NASA has a short and informative article on the purpose of the plane's winglets.

During the 1970s and 1980s, NASA research led to the development of vertical extensions that can be attached to wing tips in order to reduce aerodynamic drag without having to increase wing span.

Also back in 2012, Boeing wrote an article on their 737-MAX fleet's winglets which I assume would included the MAX8 fleet: The winglet update reduces fuel burn by an additional 1.5 percent over long ranges.

Examples: 737-700 "Upper" winglets only

737-800 "Upper" and "Lower" Winglets

737-700 "Upper" and "Lower" winglets:

737-700 has 143 seats, 24 rows

737-800 and MAX8 have  175 seats, 30 rows

Same number of seats in the defined models regardless of what type of winglets are used.
