Oil and water don't mix. Yes, the water being injected should be WELL
atomized. Same as the fuel !! Excess fuel is far more likely to "wash" the
oil off of the cylinder walls than water is , since oil is fuel soluble !!

See my immediately previous post about NOT needing to run so rich at WOT
when using WI, and then think some more about  your stated concern
regarding wear.

As for getting water into the oil--combustion of petrol produces copious
amounts of water anyway, all you are doing with WI is adding more, not
adding anything foreign. My comments have been about steady state running.
Might well be a good idea to put a thermostatic cutoff on the WI--don't
enable it until the engine is warmed up.
