What do you mean when you say the light goes on when you need 13.5? Light goes on when you need 13.5 gallons? Or did you mean to put 3.5 gallons?

Man, you must love to drive, or your commute to and from work is insane.........

 

I mean that when my light goes on and I fill up, it's normally around 13.5 or so (2.4 gallons left in my tank). If it doesn't go on, it's around 13 (sometimes a little less).

 

Oh, now I understand
