2021 Crosstrek Premium 2.0L with CVT. I just hit 20k and did another oil change, admittedly about 1k miles too late as costco took about a month to get my oil out to me. The last 2 oil changes I've collected less than 4 full quarts of used oil. I put about 4.5qts new oil in and get roughly 3.2ish used oil back out of it. Is this an unusual amount of consumption? Worth taking it to Subaru for? I dont drive crazy or anything, no silly engine mods. Only have wheels/tires, mostly hwy driving on cruise control in eco mode bt 65-75 mph.
