It seems like I paid $60.00 to fill up at $4.19/ gallon so that equates to 14.3 gallons. The low level light was not on constantly but was fading on and off. I believe our tanks hold 15.8 gallons so if all of this information is correct I only had 1.5 gallons left and technically the light wasn't constantly on. With this math I better find some gas before or immediately when the light comes on! The only reason I ask is because I didn't want to stop and put any gas in my car that contains ethanol. Only ethanol I would run is E85 and it is not readily available to me. I appreciate you response!
