The gas tank is pressurized and vacuumed or something. Actually have to press a button to open the tank to put more in. If you don't use the gas engine for 6 weeks, it runs for 15 min to lubricate. If you don't keep the average gas age below 1 year, it will run the gas engine until the average age is below 1 year. And that logic is very much as a software developer would expect. It burns half the gas away and you refill it? Average age is now 6 months. In 6 months it'll do it all over again.
