[TheForge] new question, quenching oil

[lee robbins]

has anyone had any experienced quenching oil hardening
steel in hydraulic oil. i emptied my backhoe after
draining the system to fix a pipe and added fresh oil
and the old stuff seems perfect. I wonder if anyone
has had experience with this and if there is any
reason to avoid it.
