The longer I have the car, the more I like the LED gas gauge. Here's why:
There are 16 or 17 LEDs in the gauge (tried counting while driving today...not a great time to do it
). If you break it down and include a gallon of gas after they are all 'out', each LED then represents about a gallon of gas. With the LED system, you essentially have a very close estimate of exactly how many gallons you have left in your tank. Pretty cool actually.
