Question about shelf life for gasoline

[Diamondpilot]

The marine stuff looks black in the bottle, but pours dark blue. Same product, and in my experience better suited for the crappy gas available. The other concern with long term storage is phase separation. Essentially the ethanol in the gasoline wants to absorb moisture and will eventually settle out of the gasoline leaving you with a corrosive water/ethanol layer and a low octane fuel layer. You might also consider a product called Star tron. According to the marketing hype, it is supposed to prevent the above problem.

I run a 5000w Honda to power most of my house during outages. I learned the hard way that untreated fuel causes issues of not used within 6 months.

The Star Tron is blue as you can get, sky blue to be exact. I see it all the time at WalMart in the fishing section where they keep Outboard 2 Cycle oils. Star Tron Enzyme Fuel Treatment - HOME

Just for info..... I recently read that the Sta-Bil Marine (green) and the Sta-Bil diesel formula (brown) are a different color because of the issues created from putting "red" Sta-bil into diesel fuel ......... making it appear like the dyed home heating #2.

The Sta-Bil website even mentions this situation.

Diamondpilot, cant use HHO around here for tractor or genny. Its 100% kerosene ( keeps the outdoor tank from gelling ), but lacks the lubrication of the diesel fuel. They might run, but not very long. Thanks for the opinion on the marine grade Stabil.
Ironhand, if you have had treated fuel last 6 months, then I guess I would be safe pouring in the correct amount of the marine grade Stabil to treat 190 gallons and keep it fresh for the 2 months it would take to use it up.

Its 100% kerosene .

I find that extremely hard to believe.

Not hard to believe at all. Most smart folks up here that have their tanks exposed to the cold use either full kerosene or a strong mix with #2 fuel oil nearing 50/50 at least.

I am trying to dispel the myth "my outages only last a few hours or a day". If you have a major event (hurricane, ice storm, wet snow) that affects a large area, then your outage can last a long time. Also the longer an outage last the more you will need a generator. Admittedly the longer outages are rare, but when you have then you need the generator. Two hour outages don't really require a generator, unless you have some medical needs.

I like the 5 gallon cans since you can rotate your stock. I put the newest gas towards the back of the storage shed and use what's in front first. I always add Stabil when I fill the cans at the gas station. I try to fill vehicles if I see a storm coming (not always easy to do). I have a method to get gas out of all of my vehicles.

You guys like paying more for weaker fuel?

We just treat #2 diesel but if you want something thinner than #2 wouldn't diesel #1 be cheaper?

So what do you use in the tractors?

 

[SARG]

I suppose the answer is a weak fuel beats a frozen fuel hands down .... especially during a blizzard.

The color is dependent on the brand. I like the STA-BIL brand avaliable at TSC, Rural King, WalMart, ect. $19.99 will treat 300 gallons or so and its black.

We have had the best results with it taking care of about 75 engines from tractors, boats, ect.

Again- not to belabor the point but it isn't black here...it is blue.
Even the link you provided clearly shows in the pic it is blue
