That gear lube study caught my attention. Particularly this line:

that is too thick, however, has disadvantages. Thicker oils are more difficult to circulate, particularly in cold temperatures,
and wear protection can be sacrificed".that is too thick, however, has disadvantages. Thicker oils are more difficult to circulate, particularly in cold temperatures,
I switched to 75-140 some time ago and it has improved my tranny performance but now I'm wondering if it being heavier than the 20-50 recommended is increasing the tranny wear.
Any thoughts?
