AX15 gear oil?

[Starfish Prime]

Changing the oil in my AX15 soon.
Any thoughts in Redline MT-90 vs. Pennzoil Synchromesh?

Any other product I should consider?
Thanks

Definitely go with the full synthetic Redline MT-90 and avoid (!) the conventional Pennzoil Synchromesh. Too many bad reports of poor shifting traits after the use of Pennzoil (or GM) Synchromesh.

Thanks! Just learned I should use GL3/GL4 because GL5 has sulfurs that don’t play well with brass synchros. Evidently Synchromesh is GL5??

I don't know what its GL rating it is, I can't even find it, but it's not a GL-5. Their technical data sheet at https://www.google.com/url?sa=t&sou...FjAAegQIARAB&usg=AOvVaw3S7QL5Z04t5ReLnoZzJLe- doesn't say what it is.

Redline is a gl4. Check out the video by jeepsolid on YouTube. He uses it in his YJ and goes over all the specifications of the oil
