Product Information

Red Line MT-90 is a full synthetic, ester-based 75W90 GL-4 oil for manual transmissions and transaxles. It lacks the reactive sulfurs found in most GL-5 oils, so it is safe for brass synchros, and it is less slippery than many GL-5 differential oils, which gives proper synchro friction and quicker shifts without notchiness even when cold. It also covers gearboxes that call for 80W90 or 90 gear oil or SAE 40, 10W40 or 15W40 motor oil, but it is not for hypoid-gear differentials.

Can I mix it with the fluid already in the transmission?

  • Yes. It is compatible with petroleum and other synthetic oils.

Can I use it in my rear differential?

  • No. MT-90 is not for use in differentials with hypoid gears.
