The ISX has the least amount of internal wear at 1500-1700 rpm range 1600-1650 being the center point, especially when climbing hills, etc.

RPM's much below 1400 will cause the most amount of internal wear when under any kind of heavy load application.

I have the smaller brother to the ISX, an ISC. My gov runs up to 2400rpm. I figure that a similar rule could be applied to the smaller engines, maybe least wear around 1800 rpm? It seems to like pulling there best.
