Right now I have one 5 gallon jerry can of gas with some stabil in it. I try to rotate it out every 6 months or so but I could probably leave it longer with the stabil in it. I want to try and up the amount I keep on hand to be around 10-20 gallons as that should be plenty for any outage I don't need to evacuate for beforehand. I've tested out my maximum load on my generator and it's about 50% of its total capacity. The spec sheet says that should last about half a day. The tank on the generator holds about 1 gallon.

So 5 gallons in theory should last me 2.5 days at maximum load. That includes an AC and a refrigerator blowing constantly (which under normal circumstances they wouldn't be).

Should I just load up on a couple of jerry cans with ethanol free gas and some stabil and call it a day? Or is there a smarter way to go about storing gas?

You may want to recalculate that, 5 gallons runs my 5500kw generator overnight with a window ac unit. I run my fridge and freezer few times a day to keep them cool.

This is a 2000 watt generator. So my peak load I calculated with a smart plug that measures wattage is about 1000 watts. I made sure to have the AC running and turned the fridge up before so the condenser was on. Still peaked around 1200 or so watts.

So my calculations may be a little off but I feel like they’re close.

Wouldn’t it be easier to go get gas several days before the storm? Not the day of/before when there isn’t any left. But why not wait till there’s a threat. At
Least in the Gulf?

I'm trying to increase my perpetual stockpile. I keep 5 gallons on hand at all times minimum as it is. I want to up that and want to know the best way to go about it.

I am betting he has a Honda EU2000 generator or one of the Chineese copies, the fuel consumption is very low. I ran a 5000 BtU ewindow unit, Frig, and some lights on about 2.5 gallons a day.

Take it from the boat if you have one.

It's a Champion. I plan to get a second to run in parallel as well.

I think you are overthinking this. If you have something else at your house that uses gasoline (mower, boat, etc.) you could always load up however many cans you want and rotate through the oldest in your household equipment and refill cans as you go through it. However, you would need to know the expected beneficial life of the gas in the cans and weigh it with how much gas you go through in these other items.

Gas in a can in the shop unused isn't as big of a deal as gas in a machine that sits around for a year without being used. That's when you start seeing the harm.

I have 33 gallons in my truck, 18 gallons in my wife's car, and 21 gallons in my boat. I also have two 5 gallon cans for my lawn equipment. If we have an impending storm everything gets filled up in advance. All will be available for the generator if needed.

In your boat!

We have a dual fuel, I broke down and bought a 100 lb propane tank to have on hand plus I have the fuel in my boat. I also have 6 5 gallon cans that I use to keep full during hurricane season, I got tired of rotating them out at the end of the season so that is where the 100lb tank came into play. I can always fill them up if before a storm or I have enough fuel to make it a few days for the gas stations to get up and running again.

Styrofoam ice chest. It seals tight so that you don't get as much evaporative loss.

I keep a two 1-gallons cans of 4-cycle TruFuel, that's enough to run my generator for several hours in a sudden power outage, enough time to either fill up a larger gas can or siphon from my truck if needed. TruFuel lasts about 5 years unopened so I don't worry about it colleting dust on a shelf in my garage.

Project farm (YouTube) has a good breakdown about fuel stabilizers...definitely worth looking at.

Ethanol is the devil in fuel, but I use it all the time in everything and never use a stabilizer. I just don’t let it sit for more than a couple of months.

I also have a champion generator and it’s been dead nuts reliable for years and has seen continuous use for days.

I personally don’t store gas for long and just fill up the cans when I expect to need the generator. The generator is always full but I run it regularly to keep it from sitting.

If you really want a game changer- buy you a battery operated liquid pump. They are like $10 from HarborFreight. You’ll never pour from a can again.

That’s what most people do and it sucks. Even if you have 4 five gallon cans full that’s only around 48 hours of run time. I store 80 gallons every year and have never had a problem. If you don’t use it you can fill up your vehicles

I run the generator every 3 months to just make sure it doesn’t sit idle for too long.

I have a safety siphon and it works like a dream.

Buy ethanol free. Keep in airtight container. Don’t waste your money on stabilizer. I running some non ethanol in equipment that has been stored properly. It’s al least 6 maybe 8 years old. Don’t let gas sit in equipment.

This is a great question as I have the champion 2000 just to run my fridge. That’s all I care about running.

I just rotate it every three months. Everything in my cans gets put in the truck every three months. Hen refill the cans. I lose very little via vapor and bad gas.
