Propane is BY FAR the best fuel. No mater what fuel you are using your gonna
need fillups. Oil is cheaper but much dirtier and requires more maintenance.
Electricity is the MOST EXPENSIVE. All you people out there with your electric space
heaters be warned!!!
Seminole, a 10 gallon variation like that is strange. If you leaked 10 gallons in a month
you would smell it. Go to the tank, open the cover, and take a whiff. Also listen
close as you can hear most leaks.
In theory a 120 gallon tank hold should show 80% at 96 gallons. Some guys will
fill them to 90%. The guages are NOT ACCURATE abd lock up constantly. Unless
it happens again I wouldn't worry.
