Fuel Saving Tips
Quite often your odometer reading will differ from your actual distance travelled. Usually it is over reported, so that you think you're driving faster and travelling farther than you actually are. This can be 5-10% in many cases, which would decrease your mpg by 5-10%. Use a GPS unit to measure your actual distance travelled and compare it to your trip meter. If you're GPS reads 100 miles, and your odometer reads 105 miles, then you should divide your fuelly entry by 1.05 to get it to 100.
