We need to know if "F" with the new heads or old heads... Change in Produktion should be applied in March 2015.

2015, F engine, prod. 11/14, in-service 1/15, slightly less than 5,000 total miles. No big track, only autocross use-- two seasons, 16 events @ maybe 15 miles per event = 250 "track" miles in 1st and 2nd gear, with occasional short burst in 3rd on some courses. No problems at all until this week, when having 24-month service done, dealer drove car after oil change and got a code thrown for oxygen sensor failure. New sensor ordered and going in tomorrow. Only 1/2 quart oil used in last 3500 miles.
