Ok so everyone says to watch out for glycol in washer fluid, don't inject it into the engine.

I run a mix of waste motor oil. I found a shop that says they dump brake fluid in with their WMO... The problem with this is that some brake fluids contain glycol. I was wondering if people say not to run it because it ate trough the plastic engine block casting on a honda civic :lol3:
I have run my truck on everything motor oil, ATF, hydrolic fluid, mixed with paint thinner, ISO Heet, gasoline, vegetable oil. I don't know, i don't really foresee it killing my cummins, but is this a really horrible idea and where i should draw the line????
