Got this low oil warning couple of days ago, message said that I had to add 1 qt of oil. Checked with dipstick, the oil was indeed low !!! Added 1.5 quarts of oil (Mobile1 synth) to bring it back up to normal level.

8000 mi, but was recently driving on regular gas, if that makes a difference... But now switched back to premium...
