If you've lost 1/4 of your oil, and it's very dark, you should change it now
And you might have another problem, dark is normal, but losing 1/4 on a 2014 car is not normal.

12.05 @ 226 miles stomping on it frequently and for extended periods 93 non ethanol 18.76 mpg (over 100 miles of that was at Road America on the track)
13.87 @ 327 miles mostly around town and some stomping on to the floor on 93 non ethanol 23.5 mpg
*8.80 @ 245 miles mostly hiway but two(2) to the speed limiter runs on 93 non ethanol 28.85 mpg
*7.92 @ 246 miles same trip coming home, no high speed runs on 93 non ethanol 31.1 mpg
-- 12.47 @ 378 miles typical mix of driving to/from work mid summer on 93 non ethanol 30.31 mpg
12.05 @ 225 miles towing a 5x10 enclosed trailer with 2 motorcycles inside 18.68 mpg 89 10% ethanol fuel (all they had)
-----8.38 @ 176 miles towing same trailer following tank with 93 non ethanol 21.00 mpg
---------------post lowering car, Airaid intake, Bama tune, driveshaft-------------
13.49 @ 292 miles towing same trailer, same 2 bikes... 91 10% ethanol 21.65 mpg
-----10.62 @ 283 miles dido cept ... on 93 tune --93 non ethanol 26.65 mpg
12.90 @ 233 miles dido cept.... 0n 87 tune--still 91 10% ethanol fuel 18.06 mpg

-- 12.59 @ 378 miles no towing, my typical 2 work weeks of driving on 93 tune, 1 time to 145 mph-- 93 non ethanol fuel 30.02 mpg

So I pretty much run 93 non ethanol exclusively unless I just can not get it and run on the 93s tune

no runs with the bbk's yet and no new tune for them either, only have about 100 miles or less on them and it is winter.

some can be directly compared
