so this is the 3rd time im changing my oil, but this time i drained maybe only 3 1/2-4 quarts out? i filled it with 5 1/2 of Mobil Full Syn. exactly 5,000 mi. ago. No leaks, no harsh driving. The only thing i can think of is it just burned up real fast for some reason, or Mobil 1 had a bad batch idk.
please help!
P.s. i filled up this time on Redline.
