Optimum High Idle
in Engine and Transmission
Posted
Hello all. I'm new to the Mack thing. I just purchased a 2000 Mack, CX618. It has a Mack 460 hp engine, 13sp Eaton with 3.70 rears. What is the optimum high idle. My manual says 1200 to warm the truck up but I'm looking to know for when sleeping for the least amount of wear and tear when idling is necessary. Thank you for any replies.
