Evan -- That's the only way you *could* drive a 2 cycle Green Leaker. Otherwise it would over heat or you couldn't shift it. At least for the 71 - Series, they only ran happy if they were against the governor (2300 RPM). I'm not sure about leaking -- AMTRAKJoe can corroborate this as he rode with me. But on the trip out and back to Kansas city a few years ago (1,400 miles, all Interstate 2300 RPM most of the time, screaming happilly) ... on the trip home, we topped off the oil in KC. When we got to White's (Racine, VA) two days later to refuel, we did not need oil and the engine wasn't leaking. Once we got home and the truck sat for a week, it started leaking again -- about the same time our hearing returned ...
The transmission was seeping a little, though ...
In my limited experience (with one 6-71), that engine was happiest when it was wound all the way up and kept there. 2300 rpm, 62 MPH all day long. It used less fuel, it didn't burn oil and it didn't leak. For people used to lesser engines that don't like the top end, it might take some getting used to.
2 cycle Detroits -- drive 'em like you stole 'em and they'll love you long time.
