Battery Cable Upgrade

I performed what is known as the big three electrical upgrade. I replaced the block to ground cable, the alternator to battery cable, the battery to starter cable, and the battery to ground cable (yes that's more than three). I am not sure of the exact mechanisms behind the upgrade, but I have noticed an increase in my FE. In previous winters I would average an abysmal 15-16 mpg in my Jeep. The last two fill ups I got ~18.5 and 17.2 mpg. That is a definite improvement, especially when factoring in the less favorable driving conditions I face this winter. I would recommend this upgrade to anyone who still has their flimsy OE battery cables.
