The HPOP reservoir is fed oil from the LPOP. No need to change it separately, but a lot of folks like to. I did it once when I changed to syn, but it was a bit messy. There is a small access port on the top of the reservoir. You can open it with an allen wrench and sneak a thin tube in there to drain it if you like. A turkey baster kind of thing or syringe would do it, but thinking about it now, a long enough thin siphon tube run down to a drain pan would probably work and not be too messy.

I do it every time. Only about 80% of the oil is drained out when you change the sump, and that leaves 1/5 of the dirty oil to mix in there with the new oil. I drain the HPO reservoir when i do a oil change. I have a vacuum canister with a hand pump on it and a tube you can easily stick down into the reservoir and you get at least a quart out. Refill to the top and the injectors get a nice treat!

I've never changed the oil in my HPOP, some folks like Kris do it every time. It's really a matter of preference. One thing you may want to try is knocking a hole in the bottom of your oil filter to drain it before you go to unscrew it all the way. Easier to handle and smaller chance of spilling a bunch of oil.
