According to the people that make and sell the stuff, it does!!!!!!!!!!
I have an uncle that is a retired chemical engineer,back in the 70s/80s, the company he worked for did testing of various
oil additive products...he said for the most part,back then,the stuff does not much more than thicken the
oil....I do remember they tested STP and another brand of
oil additive that I can not remember the name.....
According to their testing,he said as the oil cools down when you shut the engine off, it thickens the oil and makes it "clingy",so it does cling to the metal parts better helping reduce a dry start-up the next time you start the engine,he said that's about the only thing good they could find........whether it is worth the time and money to use it, is up for debate, another day.......
He also said if these oil additive products were that good, the manufacter of the engine (Ford/Chevy/etc.) would recommend them.....how many do????
