Looking for that sweet spot of performance and economy/efficiency.
For highway driving what is the ideal engine RPM (or range) for a 2001 unmodified 4.0L?
I am not concerned about vehicle speed as the ideal RPM range will most certainly result less than interstate 80mph.
My XJ - automatic, lift of 2" with 30" tires and happy to drive in the far right lane if need be.
Many thanks!
