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.

YOU MUST FILL IT TO THE HOLE ! or the wheel bearings will not get any oil... To all who have not filled there rear/front ends the wheel bearings will fail and the cost is extreme compared to a couple of quarts of oil , All brands mix does not matter if its synthetic or conventional, but running it low WILL result in catastrophic failure. just fill it.
