The 99 cent store RTV is so generic, it wasn’t very specific, except that it was supposedly for automotive use.
No further information. No mention of gear oil and/or differentials
Aren’t 99 cent stores . . . and the various spin-offs, such as the dollar store . . . the kinds of places that sell motor oil that is not suitable for modern automotive engines?
I seem to remember we talked about this a few years ago . . . ?
