Subaru Owners looking to save on gas...
Here is a little trick I just learned, it may already be known by many, but at any rate. On Subarus at least from 00' and up there is a fuse socket in the under hood fuse box, look in you manual as to which one, place a 15 amp fuse in there and that is an override for the AWD system, it effectively and safely places the car into front wheel drive mode.
Since spring is here, there is no threat of snow or ice, gas is $2.39 a gallon, and it is just long dry road trips ahead, I switched mine a week ago to test it, I am getting better than 32 mpg in my Outback sedan, before I was getting around 24mpg.
