Compression numbers are within acceptable range of each other. Very strange.
Did you, by chance, see if there's a different oil dipstick between the two? That changed between engine years on my old car; wonder if it could be the same for these as well. Oil fill spec itself from a pan drain and filter change is 4.25 qts (4 will usually do it in my experience).
