I run my generator every couple of months or so under a light load.
Lots of other ways to lose electricity besides ice storms.
Tornadoes and straight winds have knocked my power out too.
A couple of years ago some copper thieves broke into the substation for this area to steal the copper grounding wires and caused a fire that knocked power out for most of the day and caused a million dollars in damage.
OEC guys were amazing to get power back on so quickly.
guess i better put the carb back on mine. would not run last year, so i rebuilt carb and need to re install .. lesson learned dont leave old gas with condensate in carb
I use avgas in my small generator. It has a 5 year shelf life.
Extra gas is no ethanol with stabilizer bought after the refinery change over to the winter grade of gas. I rotate it spring and fall.
I run my diesel generator every 1-2 months with a 220 heater that puts about 60% load on it.
Diesel is easy to store. Add conditioner each year, and rotate every 2-3 years.
It will go 10+ years if things are perfect. You can send in a sample each year to know what you need to add to it.
I don't think the added expense is worth it. I just rotate it.
