I used to think gear oil was gear oil until I did some reading of my own. It seems that a lot of todays gear oils use detergents that actually eat up the metal parts inside certain gear boxes. The metals at risk being "yellow metals" that many old vehicle gear components contain. Even the M35 guys strictly warn against using non yellow metal safe gear oils.
I was just wondering if our GMC's have to follow the same rule of sticking with a "yellow metal safe" gear oil. Seems to me like they would. Although I have not been able to find any information to support this, and it seems like a very valid question to ask regarding the maintenance of our GMC's.
