My gauge is broken so I have to calculate it every time. I filled mine up last week when the gas light was on and put in 14 gallons (didn't quite fill it but whatever) I only went 192 miles before the gas light came back on :th_scratchhead: Sucks for me, wasn't even romping on it...Clean air filter, less than 5k on the plugs and wires, fuel filter is less than a year old.
