I've found that on the Diesel's I've owned, the sweet spot is 2000 rpm for mileage.
Oh yeah- 55-60 @ 2k rpm IS the sweet spot for the best mileage i've seen so far. The thing is here, if you're doin' 55-60 on the highway, you're getting flipped off and passed and honked at by everyone! I averaged 7.5 to 8 mpg with my loaded trailer doing 55-60 in traffic during rush hour. Not as bad as I thought it would be.
Where is Columbia County? I used to live in Montgomery County PA.
