In addition to the first oil change contradiction, the track prep manual also indicates that you can go WOT after 500 miles, but no track duty until 1500 miles, whereas the standard manual states a blanket 1500 mile break in period. I am left wondering which to follow! I may go with the track prep manual, to be on the safe side with the oil change, as well as having a justification to go WOT at 500 miles
