'22 honda navi; at 600 mile service I was told service manual calls for engine oil in rear diff...not gear lube (owner's manual doesn't mention what to use...unless I didn't read closely enough)...
my question...how common is it to spec engine oil in a rear diff? I'm gonna have to 'play the game' during warranty but I'd rather use gear oil afterward...
