Red Line MT-90 75W90 GL-4 Gear Oil is a fully-synthetic, ester-based lubricant engineered for manual transmissions and front-wheel-drive transaxles. It offers a shear-stable formula that maintains consistent viscosity in both warm and cold conditions, reducing gear noise and improving shift quality.
- SAE 75W90 GL-4 gear oil with viscosity similar to SAE 5W40/10W40 engine oils
- Popular for use in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions, and Atlas transfer cases for off-road applications
- Delivers quicker shifts and ideal synchronizer coefficient of friction
- Safe for brass synchros—formulated without reactive sulfurs found in most GL-5 oils
- Provides high-performance gear protection and extends synchronizer life
- Eliminates notchy shifting, including in cold temperatures
- Meets viscosity requirements for 75W90, 80W90, 90 gear oils and SAE 40, 10W40, 15W40 engine oils
- Recommended for GL-1, GL-3, and GL-4 applications, as well as most special synchromesh fluid requirements
- Not suitable for differentials with hypoid gears
- Compatible with petroleum and other synthetic lubricants
