Porsche No. 6 is a delightful, trouble-free '88 Carrera that runs like a fine watch at 140,000 miles. The engine has never been opened. It is a daily driver, neither abused nor pampered but driven aggressively by a serious track competitor before I got old. At this mileage and age (the car, not me), if I want to save the car, would it be wise to be less aggressive with the throttle, perhaps with a "normal" red line of 4000? Second, this 911 has always had "ordinary" Castrol 20-50. I have no interest in synthetic at this high mileage, but would a "high performance" Castrol be better (or is it the same stuff in a fancier package?)
