Mixing in the rear end

[Luvlegs]

My mistake - while at parts counter, asked what rear gear lube to put in differential - he gave me one bottle - I asked if that was enough for a complete fill - he ran and grabbed another off the shelf. AFTER I put all of one and almost all the second in, I noticed he had given me one bottle of Mobile 80W-90 and one of 80W-140 - I never thought to check the two. All of the 140 went in and darned near all the 90.
Do I empty and start over or go with it for a while and then change out?

On the positive side, I also found that after a few taps with a hammer to loosen, the plug came out nicely using the end of a short 3/8" extension (I didn't have any square drives).

It's starting to look pretty so heres a quick pic too.
