What the heck does " It is generally advised to run the engine past 4500 rpm[1]. Consistently running the engine below 3000 rpm may harm it.[1] " mean?
Can someone put this in context? does it mean occasionally make sure you exceed 4500 or habitually travel at excess revs?
Anyone got the book that is referenced to shed light on this strange comment? (^ a b c Leffingwell, Randy (2002). Porsche 911 Buyer's Guide. MotorBooks/MBI Publishing Company. pp. 188. ISBN 9780760309476.
