That isn't much gas at all unless you are just running the generator for a few hours each day.
I've got a 5500 watt one that I run 24/7 after a storm. It uses about 10 gallons each 24 hours.
After being without power for 3 weeks after Wilma and having to pay someone a lot of money to drive a 55 gallon drum over from the west coast I now go into these storms with close to 200 gallons of gas stored in
two 55 gallon drums and a bunch of 5 gallon cans. I
modified my generator fuel line so that I can run a line back to a 55 gallon drum and run it off of it.
I'm always afraid to leave my house unattended after these storms. The house right next door to me got looted after Wilma. My office is right next to their house but there is a wooden fence between us and I didn't even know they had been robbed until my neighbors got back into town and told me.
