.....why I said was the new regulation says you can only put 17 lbs in a 20lb tank...less then the 80% rule. Many places still do 80% but it is no longer legal because of issues with the OPD. Guess I could have been a little clear

You could be clearer by linking to this regulation, including where it may apply, and explaining what the "issues" are with OPD valves so we can all see judge for ourselves. My tanks are always filled to 80% capacity - 5lbs for my 5 pounder, 10 lbs for my 10 pounder, 20 lbs for my three 20 pounders, and 30 lbs for the two 30 pounders that were on our previous travel trailer ... all weights verified before and after filling, as is my usual procedure, by putting the tanks on a scale ... also verified by the Costco fill slip I'm handed by the tech who weighs the tank before and after each fill.

Yes, please do clarify this issue. Is it possible it is a New York regulation?
It certainly is not done that way here in Montana. Here, the tech connects the hose and fills until the OPD shuts off the flow or the 80% valve (spitter valve) spits out liquid propane, whichever occurs first. then the valves are shut off, the hose disconnected, and I pay according to the meter reading. The cylinder is not weighed before or after filling. If I get three cylinders filled at the same time, the meter is not reset until all three are filled to 80%, then I pay for the meter reading, which is the total for all three cylinders. That is the way it is done everyplace I have purchased propane during the last 20 years, in several states in the West.
