doing this will destroy them and their ability to function properly. Seen it plenty of times. I have no idea why people think they can get away with this. - Perhaps some mis-leading/bad information off places like ttr or some other garbage-dump truck tuning forums or social media.
as far as gear oil goes, use a GL-4 instead of a GL-5 if your concerned about the sulfides and the DOC. Sta-lube makes a decent one...
