Jakes and high boost?

[Jarhead79]

I was told to run the he'll out of it when overhauled. What pissed me off is KW let it idle for an hour at low rpm. Oil was changed at 3,000 miles now have about 8,000 on current. 6.5 avg for 3,300 miles. I hate the black oil after you run engine for an hour on fresh oil. Idle is at 17% for the trip.
