Default M-22 Trans Gear oil Question? has anyone used Valvoline synchromesh???
Hi Guys,
Time to fill up the M22 with fresh gear oil. Normally I use the oil school Valvoline Gl-4. 80-90 in white bottles. Someone recommended The new Valvoline Synchromesh. Anyone have any experience with this stuff in their M22 or M21 transmissions?? I called Valvoline and the tech help said it is rated as a GL-4 and “yellow metal friendly”???
