Fuel Saving Tips
Yep, cant believe I didn't know this, but when you run your defrost, even with your AC turned off, it still runs the AC Compressor, I just did my first test and got an extra 1.8 mpg, which is a lot considering my truck usually only gets around 12. That means all winter long, I was just wasting gas because I always leave my defrost in the on position.
