You don't have to if you are looking at is being some kind of system cleaner. If you are looking for something for that purpose, something like Techron fuel system cleaner would do the job but there is a catch for it to perform best. Dump a bottle of whatever cleaner you choose to use before you fill the tank to get a good mix and then run it until it is almost empty before you refuel it (fuel light comes on is good enough if the vehicle has one). I do this twice a year to make sure the injectors stay clean. It may clean other things but that is the primary purpose.If you have it available, how often should you run a tankful? Thanks.
Storing a vehicle with an empty tank might work in Florida but not here, when temps drop moisture will condense in the tank. I store my truck and Mustang with full tanks and a heavy dose of Marine Stabil. In the spring I drain 10 gallons or more out of the Mustang and replace it with fresh gas. My truck and Escape don't mind 6 month old 93 octane, the Mustang doesn't like it one bit. I tried running non ethanol in the Mustang but all I can get is 90 octane and I had to pull the timing back to run it.I'd only use it for storage, but only short term. If you know you're not going to use it for a long time, drain the tank and protect it with something to keep if from rusting. There's a few ways to do that. Easiest would be to fill it with Diesel and then recover the Diesel before using it. IMO it's better to use a vehicle then let it sit too long.
Florida is terrible for vehicles, both inside and out. I don't suggest storing any vehicle with an empty tank, unless it's in the SW desert or in climate controlled storage. I recommend draining the tank of gas and filling with Diesel or something like K1 that you use otherwise. IMO fuel stabilizers are snake oil. Gas is not meant to be stored, regardless of what's put into it. Diesel and other non volatile fuels can basically be stored indefinitely. I still think it's better to run the engine once a week or better yet drive it. Vehicles are not designed to be stored.Storing a vehicle with an empty tank might work in Florida but not here, when temps drop moisture will condense in the tank.

All our gas should be non ethanol, it takes more energy to produce ethanol than it produces, my experience showed a 5%+ decrease in mileage with E10, and the smell of E10 coming through a cold catalytic convertor would make a buzzard puke. Not to mention the fuel system damage E10 does to anything carbureted.
...communists of the 13 familes/WEF don't want people to have energy sources they can't fully control
...reason for the push to modern EVs...to remotely disable or limit the use of all vehicles
...control what you do in your homes when it comes to energy
beware of algae forming in hot weather, it likes diesel fuel.I'd only use it for storage, but only short term.
