fuel/oil
 

would anyone know if it would be ok to run 50/50 or 25/75 of oil and diesel together with an airdog and it would be plain used motor oil and i would be running it in a 02 24 valve

As long as you have a way to completely filter out ALL steel shavings, and remove all water/moisture I would think you would be fine. Infact Ur pump will probably like it bc of the lube. 50/50 seems a little too much tho to me. I'd stick with 25% or less.
