Alright, has anyone tried GM's manual transmission fluid otherwise known as GM Synchromesh? My wandering around looking for Royal Purple motor oil led me to a DSM forum where they said this stuff worked wonders and worked even better than Redline, RP, and BG.
If anyone has ever used GM Synchromesh, even on non-Mazda vehicles, I'd appreciate your input.
