1 can of propane 16oz-less than 5 dollars.
use the money you've saved (you now have twice as much gas!) and buy an AI (airsoft innovations) propane adapter kit and it comes with silicon oil. Follow instructions that come with AI Adapter.
A little bit of math.
Cheapest I've ever seen Green Gas-$15.00 plus shipping (and that retailer was alberta based and it was a sale) FOR AN 8oz CAN
I can get 3 tanks of Propane for $15.00 at the local crappy tire when I go to get new lightbulbs. 3 cans times 16ozs. Thats double the size of can X3.
EDIT: I've typed this out like 4 times recently. THIS IS SOLID INFORMATION.
