I run the car pretty hard, It sees 6 or 7 thousand on the tachometer daily, a lot of full tilt on and off ramps, and doesn't go more than a couple of days without seeing triple digit speeds (on a track of course). I also maintain the car very well. I have been running Mobil one since 20 thousand and K&N filters since 35 or 40 thousand. I have a oil separator and it usually has a few ounces in it between oil changes. It uses no oil between changes. I go anywhere from 4 thousand to 6 between changes and this is the first analysis I have done. I also change out the fuel filter every other oil change. A lot of my runs are in the 15 to 40 mile range although the car has gone Kissimme to Plant City never going under a hundred the whole way more than once.
