Fuel Saving Tips
It's common knowledge that on-board fuel economy meters can be slightly optimistic, however, in my experience, they've never been off more than 5% from the real mathematically-calculated figures, often less than 3%. However, for those striving for the best fuel economy, these meters can be helpful for an entirely unrelated reason. They can help us all drive more economically. Regardless of how accurate your computer is, it will likely help train you to drive more efficiently when you have your avg mpg staring you in the face every time you get behind the wheel.
