Is anyone else experiencing a bad gas gauge? One day it shows that I am on empty after the previous day showing between 1/4 and 1/2 tank and the light is on and the gauge on my dash is flashing to let me know I only have ~30 miles left till complete empty and this is on even pavement, then I start my car again and it shows that I have betweeen 1/4 and 1/2 tank. I usually fill up when my OD shows ~200 miles traveled and then when I go fill up, the pump stops at ~12-13 gallons of gas, I thought the Z had a 20 gallon tank?

 

Gas gauge problems are very common, especially in the older models. Do a search, there's a lot of threads on the subject. Some examples...
