my globe works, and unfortunately shows up quite often. i had a lot of consumption issues, so i got into the habbit of seeing almost exactly how many kms i was getting to each tank.
pushed my luck one arvo, light was on, then realised i had about 30kms to the next petrol station, made it fine! (although there was barely enough fuel to power the light, let alone the engine)
lesson learned!
does everyone else's gauge drop in large increments? mine does basically 100kms, then drops exactly a quarter in one hit. doesn't make much different i guess.
end ramble...
