is 85 -140 weight gear oil good in a vdrive, also lucas oil trans additive
any thoughtsI don't know about v-drives specifically, but for other gear boxes, I've found that Torco 85-140 GL6 has always been hands down the best non-synthetic. Prolong has the best gear box additives that I've seen, as well. I don't know about synthetics.
Of course, I have a friend that runs straight STP in his v-drive.
