Comment from Miata track on Amsoil GL-4

[Bill_W]

Personally just a normal street driver but track Miata made this comment. Lots of ND Miata users have good luck with Amsoil GL-4 75w90 with shifting. Interested in any views on this. The ND Miata had issues with the transmission when first came out.

Cant comment on the miata, but can on BMW and VW gear boxes - I found that the Amsoil MT fluids were superior to everything else. Redline is often praised for BMWs, but I generally found it lost some of its feel after a year or so of use. Amsoil kept smooth shifting and great feel for the long run, and Id highly recommend it wherever it makes sense.

It's worked very well in my Toyota Corolla 5 spd.

I have heard that Amsoil lasted longer too... Gonna try a change on Red Line MT-90 every 2 years.
