30 Day Generator Rule – Use it or lose it!
Letting your generator sit unused for too long could cause you to replace it years before you should. Gasoline has a shelf life of about 30 days. After that time, it can start to break down and damage your generator’s internal components. You have to “keep it flowing” for lack of a better phrase. To do so, it’s recommended that you run your generator two hours a month around 50% load. This will keep it primed and ready. Failure to do so can cause your carburetor to varnish, preventing fuel from effectively powering the generator. There’s no reasonable way to clean it, so you may end up having to replace it, which needless to say will be costly.
