pretty sure you want to do a compression test on a warm engine.
compression test will read lower on a warmed up engine and that's the reading you are interested in.
also, that's not much driving for that period. potentially, the oil control seals may need a bit of run time before they loosen up, pop out of the rotor and do their job. oh, and agree on oil change suggestion above, you may also try 20W-50 (assuming you're using 15W-50, now).
