Throttle vs Cruise Control

[CapnDean]

I wish I could have:

 

A throttle on my truck. Just like the one on the old 53 model Chevy.  You know, the truck with the starter on the floorboard.

 

Does anybody know if setting your rpm at say 2000 and cruising down the interstate---if you would get better or worse economy & longevity out of your engine?

 

I know it would speed up going downhill and slow down going uphill....who cares....Just wanna know if there has been any research on this....

 

I always felt like when the cruise control slowed me down....it was costing me somehow!
