Title: Transmission gear oil
Post by: Zach on March 11, 2024, 08:40:04 AM

Howdy, I need to replace the oil in my t-10. Curious what you guys use. I was trying to get some sta-lube 85w-90 gl4, but it is impossible to find anywhere around here. Other things I’ve hear is AMSOIL mtg and severe gear but I am unsure. Thanks.

Not familiar with the amsoil product but from memory I believe any 80w90 (or 85w90) GL4 should work. You probably already did since you mentioned GL4 but double check which (4 or 5) is recommended for a gearbox. I think 4 but it’s been a while and I forget.

I ordered some on amazon actually but it’s no longer available I just saw. Sta-lube I think it was
