Choosing what to use from the stash is difficult!

First in, first out. I'll use the older SM jug of MC5k before I use the newer SN jug of PYB I just recently bought.

I agree with Bigdawg74. First in, first out.

Yup. I tend to use them in the order that I buy them as well. My truck gets only PU for now but the Legend gets a variety of different brands (Kendall, Pennzoil, NAPA, QS, Peak, Supertech, Shell).
