If its still there,, , Compu-cams had a great writeup on why you need break in oil since the reformulation to low sulfur oils. I've personally seen $30K sprint car motors flatten the cam in 20 minutes.. Next time around we used the break in oil and wham.. Good motor no issues. Made me a believer. I also NEVER mix oils, seen two many react, turn to jello, or water thin under heat and eat engines.. __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
