Fuel Saving Tips
While not a tip to directly effect your gas mileage, it'll help everyone behind you. When on the highway try not to switch lanes erratically. This is essentially what causes traffic. The person you cut off will break (maybe slam on their breaks!) causing the person behind them to break...a little harder, etc. The same goes for when you're sitting in traffic, it's best to sit in one lane, and minimize breaking by keeping a slow constant speed. Your car will appreciate it, and by virtue of keeping people behind you from stopping you'll do a little to alleviate the traffic jam.
