RE: 120hp Lehman lube

albin man,I think your light viscosity synthetic in the BW may be a good idea. However I think multi-vis is slightly undesirable but I suspect that multi-vis synthetic meets the requirements or standards for without any VI improvers. And in that case you may have a good BW lube.
But there is one other possible downside to the engine lube oil for the transmission and that is foaming. Gears and clutches make like an egg beater and churn the oil up something fierce. I think the ATF has extra serious anti-foaming additives and that would make it the best oil for the BW.
