MY 06 CADILLAC CTS HAD LESS THAN 35000 MILES ON IT AND LESS THAN 3,000 ON AN OIL CHANGE WHEN I NOTICED THE OIL LEVEL WAS BELOW THE READING MARKS ON THE DIPSTICK. NO DRIPS ON THE GROUND. AFTER RESEARCHING I DISCOVERED THEIR SPEC IS TO BURN 1 QUART PER 1000 MILES (1 QUART PER 500 MILES IF AGGRESSIVELY DRIVEN). I TOOK THE CAR IN FOR AN EVALUATION TO SEE IF IT HIT THEIR "SPECS", AND THE SERVICE MANAGER PERFORMED AN OIL CHANGE, AND SET ME UP FOR A REINSPECTION AT 2,000 MILES. WHEN I WENT IN HE CHECKED THE OIL LEVEL, AND IT WAS LOW, I ASKED WHERE THE LEVEL SHOULD HAVE BEEN ON THE DIPSTICK AND HE GAVE ME A RANGE. IF THE CONSUMPTION RATE IS SO SPECIFIC, SHOULDN'T THE TEST FOR CONSUMPTION HAVE STRICT GUIDLELINES ABOUT WHERE THE DIPSTICK READINGS SHOULD BE? I HAVE OWNED ALMOST EXCLUSIVELY GM VEHICLES FOR MOST OF MY ADULT LIFE. EVEN IN THE ONES I'VE KEPT FOR 150,000 MILES PLUS, I HAVE NEVER HAD EVEN ONE OF THEM LEAK LET ALONE BURN OIL AT THIS RATE. IN 3000 MILES, I HAVE TO PUT 2 QUARTS OF OIL IN THIS VEHICLE, AND THAT'S NORMAL. IT MAY NOT BE A SAFETY ISSUE, AT LEAST UNTIL MY CAR ENGINE SEIZES ON THE HIGHWAY FROM LACK OF OIL, BUT IT IS DEF SOMETHING THAT NEEDS TO BE ADDRESSED BY GM. *TR
