Description

The Red Line MT-90 is a full-synthetic, ester-based gear oil designed for manual transmissions and front-wheel-drive transaxles. It offers improved shiftability and synchronizer performance, even in cold temperatures. This GL-4 rated oil provides high-performance gear protection and extends synchro life by lacking the reactive sulfurs found in many GL-5 oils.
