I used the search but did not find enough information regarding the weight difference, the manual calls for 10w-30 and the Amsoil is 5W-30 but it is a direct replacement per the Amsoil website.


My initial impressions is. This stuff shifts VERY smooth and very direct no more notchiness whatsoever and extremely quiet. This is how I feel this S2000 should shift and I am extremely pleased with the performance and quietness thus far. With that said am I doing any harm using this weight, I trust the shop that put it in and their recomendation but just want some more feedback.

i used it for a while. notchy when cold right? new honda mtf version 2 fixes that up and is pretty much just as good. i'm on the new mtf now. when it was cold on the amsoil 2nd would crunch giving me the urge to double clutch lol

that pretty much sums it up...go with the new honda mtf.

 

I used the Amsoil for one cycle and was very happy with it versus the old Honda MTF.

 

anything was better than the old honda mtf.

 

I started to get an occasional high RPM grind (1-2) with the Amsoil and switched to the new Honda MTF. High RPM issue went away, but 2nd is super notchy when it's cold now. Maybe I'll mix the two next time!
