I CHANGE MY OIL EVERY 3000 OR LESS MILES WITH FULL SYNTHETIC AMSOIL 5W-20. I HAVE TO PUT IN 1/2 A QUART OF OIL FOR EVERY GAS FILL UP. I'M A HIGHWAY DRIVER THAT SETS CRUISE CONTROL AT 75. I DON'T DIVE CRAZY. 2007 HAS AN EXTENDED WARRANTY, WHERE IS THE ONE FOR 2006?
THIS CAR IS CONSTANTLY BURNING OIL. MY OIL PRESSURE LIGHT NEVER FAILS TO TURN ON SOMEWHERE BETWEEN 1000-2000 MILES AFTER EACH OIL CHANGE, AND I HAVE TO REFILL TO STOP THE LIGHT FROM COMING BACK ON.

OIL CONSUMPTION!!! I'VE OWNED MY 2006 SCION TC FOR ABOUT 5 YEARS AND HAVE RECENTLY BEEN EXPERIENCING A HUGE OIL CONSUMPTION ISSUE. IT DIDN'T PHASE ME AT FIRST, ALTHOUGH NOW I NEED TO SET MY ODOMETER TO ZERO AND REFILL MY OIL EVERY 800 MILES. I BELIEVE IT IS CERTAIN INTERNAL PARTS THAT ARE CAUSING THIS PROBLEM, SUCH AS THE PISTONS AND THE PISTON RINGS . I'VE NOTICED THAT THIS HAS BEEN AN ONGOING PROBLEM FOR A LOT OF SCION TC'S LATELY, WHICH HAS BEEN TAKEN CARE OF THROUGH AN EXTENDED WARRANTY PROGRAM FOR THE MODEL YEARS OF 2007-2009. I'M TRYING TO PROVE THAT ISSUE IS ALSO AFFECTING THE 2006 MODEL YEAR TOO, AND WOULD GREATLY APPRECIATE IT IF I COULD RECEIVE SOME HELP CONCERNING THIS ISSUE. I WILL UPLOAD A PHOTO OF AN OLD PISTON THAT SHOWS THIS EXACT PROBLEM.
