I was a charter bus operator over 25 years. The majority of my runs were in the Gulf Coast area(HIGH HEAT/HIGH HUMIDITY!). When on a trip less than 24 hours I would engage the high idle and sleep on the bus with the ac on. The engines were good for at least 450,000 miles before work was needed. When I need to idle my engine I make sure the high idle is on. 97 Monoco 325 Cummins
