I have a 2014 CRV 12,600mi bought in August 2013. Did first oil change at honda recommended 7,000mi (at the dealer). Recently had tire service done and was told i'm missing 2 quarts of oil, determined by looking at the oil stick. I never had oil leaks in any of my cars so i didn't bother checking. My CRV doesn't have a leak, no smoke or soot coming from exhaust. Where does the oil go? Is it normal? Safe to drive until the next oil change at 14,000mi? Never had anything like this in any of my other cars.
