My Pontiac Vibe's owners manual is available on line. As you know the base Vibe has the Toyota 1zzfe engine and the Toyota transmission. The manual states "GL5 75W-90".quote:
Or, post a picture of the owners manuals fluid recommendation page.
Our MTL-R is already a dual rated GL5/GL4 fluid and has been since February 1st of 2005.quote:
So, Redline 75W90NS would be the preferred oil for this app as it contains a GL5 level of additives but without the friction modifiers for the limited-slip differentials that most GL5 75W90 gear lubes have, at least according to Redline. But any 75W90 GL5 rated gear lube should work, so M1 75W90, Amsoil Severe Gear 75W90, etc would be fine. But it's best to use a 75W90 GL5 rated Manual Transmission lube, so contact Molakule to blend you a GL5 rated MTL-R!
