I changed my rear diff cover from factory to dana spicer which has two fill holes.
I put three quarts of amsoil rear diff oil and still don't have it dripping out of the lower fill hole.
Is is ok to top off the rear diff with another diff oil with the same weight?
IMO, should be enough until you get another quart of Amsoil. As long as you’re not towing/tromping on it.
