The only thing we know for sure is that some manufacturers, like Honda, advise in the Owner's Manuals of their vehicles not to change the factory oil until the first service (usually 7,500 miles). My question is: Why? Is it because the factory oil is special in some way? Is it because the factory does not want some eager beaver new owner to swap in fully synthetic oil too early in the life of the engine?

I am going to go out on a limb, and say that, if Honda says wait to change until 7500 miles, then it is already synthetic in there...
