I also use photographic slide album pages. They're solvent free, acid free, and they degrade much more slowly than "coin pages".
The solvents and plasticizers that are creating the "oily" feel can't usually work their way completely through a good 2x2 film (not after at least a couple of decades, anyway). But they can soak partway into it over time, making the film sticky on the outside which in turn makes the 2x2 difficult to take into and out of the pages. This process is accelerated if the pages are "squeezed" together for prolonged periods, either by stacking a huge pile of albums one atop the other, or by jamming too many pages into a closable album and forcing it shut.
I recall once going to a dealer stand at a coin show where this "solvent transfer effect" was so bad, and the 2x2s in their stockbooks had become so sticky, that the dealer handed me a dud credit card and a screwdriver so I could prise the coins free of the album. It's not a way to impress customers.
