FANTASTIC FOR TOYOTA MANUAL
I have a 2015 Scion XB (Toyota) manual transmission and changed it a few weeks ago and used that Ultra 1 GL-4 and my manual transmission started having clunky gear shifts. I just changed it to Red Line MT-90 that's actually recommended by Toyota and what a difference. Immediately felt the shifting smooth as silk. Oh well, live and learn. Buy what's recommended by the mfg because they know what they are talking about. My fault.

Manual Transmission Lubricant Supreme
Redline lubricants are a premium synthetic oil product for your automobile needs. I utilize it in my classic Alfa Romeo Manual Transmission. Redline surpasses anything that was available when my Alfa was new. It really clings to the gears and shifts effortlessly with no grinding. This product works for most manual gear boxes but always verify with your owners manual. Larry Hunt

Arrived very quickly!
I have used this gear oil exclusively in the past for my BMW 6 speed transmission, which requires just under two quarts. I only purchased one quart this time around because I'm using it together with a different type of gear oil in hopes of quieting gear rattle due to the installation of a single mass lightened flywheel.
