It is usual to see a layer of "battery oil" (light mineral oil, I think) on
the electrolyte surface of large stationary batteries. Slows evaporation and
controls mist during gassing. My only reservation has to do with the sloshing
that goes with a mobile application. I could imagine the oil not doing the
plates a lot of good if it got sloshed down around 'em.
Why not take an old battery you don't much care about and give it a try?
