I use 3-in-1 oil on the bottom bearings on my rotaries and occasionally drop some Al-Cass oil through the slides to lube the insides. The valve oil on the inside doesn't make near the difference that oiling the bearings makes.
Why - it helps make them move better.
As for pistons, they don't seem to move without it.
