1. Is regular unleaded OK or should I get gas with a higher octane?

2. How long before I should replace it with fresh gas?

A year at most, and you’ll have to use fuel stabilizer.

What are you planning to use the gasoline for?

I'm definitely no expert. But I read it's only good for a couple of months. But I had a gas can left over from my old house when I started letting a neighborhood kid cut my lawn, when I moved I decided to cut the lawn myself. The gas was probably a year old or older but my lawnmower started right up with it.

During hurricane season, I get the regular gas my generator takes and store 5-5 gallon tanks of it. If I don't use it by the end of the season, I put it in a vehicle.

Last year I needed gas around the time that Harvey hit and I had to travel about 50 miles to get some. I want to avoid another repeat.

Buy ethanol free gas. It'll last longer sitting up. That's all I use in every gas thing I have that's not a vehicle.

You might want to look into getting a Generac automatic generator that is powered by natural gas. I bought one three years ago and have weathered several hurricanes and power outages. It is nice to not worry about how you are going to do without electricity.

For a decent investment you can elect to not participate in the gas freak out after a hurricane. Our gas tank will provide electricity for our house for about a month.

Octane is irrelevant. Do not store E10, it will literally separate Ina matter of weeks

Buy non ethanol only, and with a stabilizer it can be stored for 6 mos or more

Gasoline becomes degraded due to the evaporation of soluble butanes and other distillates over time when the gasoline is allowed to contact the atmosphere. Storing gas in containers with minimal venting will prolong usable life usually into years. I have run 8 year old gas in small engines and vehicles with no problems.

I don't think octane is important....however, the use of non-ethanol is pretty critical. Trouble with ethanol is that it actually absorbs moisture from the atmosphere and can really frick things up if it sits up for a while.

I would fill everything with non-ethanol and plan to use it within a year. try to put it in something that you can seal up, if possible.

There should be a valve on the generator to cut off the gas. You can let the gas sit in the tank while burung / running the rest out they the carb. That way you can get rid of the old gas without worrying about affecting the carb

And ethanol free gas !!! Don’t chance it any other way

Don't matter.
Just keep it in a milk jug behind the fridge.

Obtain another vehicle and use that vehicle's tank to store the gas. It won't go bad.

Just buy a new car that already has gas in it. Why spend the money on something that disappears in a matter of hours

Good question. I filled a 5 gallon container with gas (likely with ethanol) in prep for Irma last September. I have only used a small amount for my lawn mower. I noticed the plastic cover has a crack in it - meaning it is not air tight. I’m guessing I should not use this gas in my car? And if not how does one dispose of 4-5 gallons of bad gas?

Just put it in your car and do a fill up with fresh gas. Try to get 2 gallons of fresh gas to one gallon of old gas.

What about in the zombie movies when they siphon years old gas out of a tank and put it in a car?

I usually get 87 octane but always ethanol free if it's going on a Jerry can with stabilizer.
