Propane Tanks 20lb does not equal 5 gallons (trimmed from another thread)
i apologize to the op as i have a stupid side question for you guys on propane filling. now it is only 5 gallons and is for my propane grill, but i only went to one place all of these years to fill it. in recent years i began to suspect them of not filling the tank all of the way and charging full price to fill it. other places to fill it are not close by so i stayed at this one place for saving on the gasoline. when they filled it the last time it went to just a bit over 4 gallons on a 5 gallon tank and i burned off any and all that was left inside for this instance. now it needs refilled again and i'm unsure if i should go elsewhere due to being ripped off or not.
