Was wondering if anyone has detailed information that would lead to knowing the most efficient RPMS. Wondering if there's some sort of BSFC (Brake Specific Fuel Consumption) graph somewhere or another useful graph to look at.

Any info using a Scangauge that would be useful? I'm most curious to find out the best RPM range to be in when accelerating. Lots of zero to 55 mph driving for me.

Thanks for any info.

I know on my odometer it has an ECO setting after the trip meter. It tells me if ECO is on or not while I'm driving so I try to accelerate slow enough it stays on.

I think newer models have that feature. My 2008 definitely doesn't. I would love it.
