Thats because it is not possible that the battery would do anything with the engine efficiency. It has nothing to do with the efficiency of the engine, aerodynamics, rotating mass, gear ratios, fuel, air, weight, etc!

 

Different gas may be part of it...the previous road trip was down and up I25 in early May and the high mileage trip was a loop was through the Rockies last week.

I did all the math because of my own disbelief, and found I saved $77.96 on this last trip because of the better mileage... I dunno, but I like it

Maybe the engine is finally broken in....lmao. I will probably screw it up tomorrow when I install the Superchips Flashpaq...Northridge4x4 just shipped it overnight air a couple hours ago!

You gotta love those guys!

 

I completely agree. I used to be an Interstate Battery dealer and never heard of any such phenomena. I am an Electronic Engineer by trade and electromechanically it makes no sense. Could be good karma...

 

X2 this is what is happening any time i have disconnected the battery this is the result i get. nothing special
