If you’re a quart low in your sedan, there isn’t enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you’re driving around the Denver area.
The transmission also needs the proper amount of clean fluid to do its work. When it’s in need of service, the transmission drags your fuel economy down.
So keep it clean and give yourself a fighting chance.
