- I am thinking about putting Redline MTL (manual transmission lubricant) in the
- gearbox of my 1985 Toyota MR2. In general I have heard very good things about
- this gearlube, especially in providing smoother shifts, but I do have a few
- questions. Redline makes another gearlube which meets GL-5 and GL-6 specs and
- the Redline literature would seem to indicate that this lube provides the best
- protection and anti-wear characteristics. The MTL meets GL-4 specs only a
- seems formulated to help the synchronizers with "friction enhancers". My
- question is, would a friction enhancer also be a wear enhancer? I know that
- the synchros need some friction to work but what are the drawbacks of this
- increased friction? My owners manual recommends GL-4 or GL-5 spec gearlube,
- what does GL-4, GL-5, and GL-6 mean? Does GL-6 supercede GL-5 and GL-4 or
- would a GL-6 lubricant not be recommended where GL-4 is required? So, aside
- from helping the synchros, how good of a lubricant is MTL? Also, I have heard
- very good thing about Mobil's synthetic gear lube. Does anybody have
- experience with it? Does it smooth the shifts as well as MTL?

- Thanks in advance,
