 Sure, water will work just fine.  Take a look at a big hydroelectric
turbine sometime; chances are it'll have water plumbed to sleeve
bearings.  Once the shaft is spinning any fluid will do - even air,
which is often used in very high speed applications.

 Automobiles use oil-fed plain bearings primarily because they already
*have* oil in the crankcase to lube the myriad things which require
lubrication, so it makes sense to use oil.
