Ok I have a 2005 Toyota Camry with 2AZ-FE engine and a 5 speed manual transmission.
I have used Redline MTL/MT90 50/50 blend for years with nothing but fantastic results. It is a pain to blend.
I have tried Royal Purple products in it and was very disappointed in cold shift performance as it seemed to lose it's cold shift performance in under 20K miles of use.
BG Synchro shift and Synchro Shift II work almost as well as Redline but by 30K miles it has lost it's cold shift characteristics.
Amsoil Sever Gear was totally disappointing from a cold shift and warm shift perspective.
I do not think any of them have had any issues protecting the transmission from wear and tear all of them come out looking and smelling like new.
The shifting though is terrible once they other fluids start to go south. Since I put Amsoil Sever Gear in the shifting has been terrible. I put this fluid in during Winter and now I am having a difficult time with 5th to 4th down shift and 4th to 3rd.Sometimes it is just fine sometimes it is difficult.
I often have to shift back to 5th and try again to get the shift to go through.
I am going back to Redline since I have never had any issues using Redline and it easily makes it to my 50K mile OCI with out losing it's shift feel and ability.
I decided not to do the MTL/MT90 blend but instead running MTL 100%. The only difference I see between the MTL, MT85 and Mt90 is viscosity.
So anyone else run 100% MTL, MT85 or MT90? Seem's like all of them are GL-4 70W80 to 75W90 and the cst at 40C and 100C all seem close enough to be interchanged. I can not see where blending MTL and MT90 makes much sense.
I will let everyone know how it goes after I drain and refill with MTL. It will be interesting to see if warm shift performance radically improves with the change. The recent problem with warm downshifting.
I lost all my records recently when my wife cleaned out my file cabinet.
