Hmm. good thought. I could always play with it to find the optimum rpm.

I try to keep it at 70 or less on highway. Fortunately for me, in NJ, it very easy NOT to do 70, or 60 or even 40 on major highways. Thank goodness for traffic congestion

 

i get worse mileage @ 60 than I do at 80, in town I burn the fuel like it's going out of style (around 16mpg in town) all the stop and go sucks

 

me too. it's not easy getting that Rhino up and moving from every stupid stop light in town, of which there are many.
