I've noticed that some of my cylinders are a bit "sticky" or sound like
they are grinding. The small cylinders and pumps have a lubricant
on them already.
On a side note, I'd be careful about what kind of oil I put into these
cylinders, since some plastics become "embrittled" over the years with
exposures to hydrocarbons. I'm going to look into plastic mold release
agents which I assume are better suited to ABS. You should be able to find
these at hobby shops.
Any chemists out there with better info than mine?
