Wouldn't the oct rating drop as it was stored? I would probably get some if a storm was rolling around. Just really wanted to discuses the topic with people who would know...ya know

 

I hope not...lol
I keep around 10 gallons of C16/117 octane in my garage,,just in case I want to head to the track on the spur of the moment kinda thing.

 

wow, throw me a frickin' bone scotty. sorry I didn't READ

 

Some gas can degrade completely after only 2 months. with stabilizer, it could last another 2-3 months. I wouldn't store gas for more than 6 months with stabilizer. Having 50 gallons stored is a pretty useless idea being that gas can go bad so quickly.
Using old gas in a supercharged engine is NOT a good idea. Old gas can cause detonation and melt the pistons very quickly.

This is just FYI of course

 

If he has a pump on the drum every once in a while use the gas in the drum to fill the truck, then replenish the drum with fresh gas as you use it. A little bit of work, but it could be worth doing around just hurricane season as a safety precaution.

 

Good grief. What a pain in the freakin ***!?! Storing gas, how long, where, lasting, etc. And what about if you can't get to the area where its stored after the storm? Even if the storm left a spot alone last time doesn't mean the next one will. Heres an idea....supercharge the hell outta the truck, get an SCT X3. It will hold 3 tunes and your pc or lap top will hold lots more. (I have at least 20 stored on mine to run the truck in any configuration I have had it in.) Point being at least one of those tunes should be modified to run on lower octane thus getting you through the bad times. Problem solved.

 

Adding to what twinskrewd suggested, if I was you I'd get just a mail order tune for the lower octane. Mail tunes are pretty cheaply priced, so it's not like your having to pay $500+ to get dyno tuned for an octane you may rarely ever have to use(natural disaster).

 

Gas can store for years...where do you get for only 6 months with stabilizer?

Where to store it? Ever heard of a shed in the back yard?

It would be good enough to get around. DO you plan on racing and going full boost during a gas shortage? Keep your driving to a minimum, stay out of the accelerator and that stored gas with stabilizer will last for years.

Seriously some of you people...

Besides that, there is this theory about rotating the gas that works wonders!

Of course, I am also one of those insane people that keep a years worth of food, several years of hygiene products, cash, silver, gold, other precious commodities, generators, lots of propane etc.

Only if my HOA would allow me to park a deuce and a half in the back yard.

 

Good for you!
There's nothing wrong with being prepared for just about anything.

What is a good gas stabilizer to use that you would recommend?

 

I have NEVER heard of gas lasting longer than one year, especially without stabilizer. Read this: http://articles.cnn.com/2008-04-09/l...l?_s=PM:LIVING

Like I said earlier, it's not a good idea to store gas without stabilizer, because the chemical composition will change after a few months, and cause problems for your motor.

Do what you like, but I'm not using any old stored fuel in my vehicles unless the world is ending and I'm stranded in the middle of no where.

 

Just thought I would share. Not here to stir the pot which is unusual of me. A lil food for thought is all.

First... Lets go back to my "rotation" comment...

2nd, I have used gas that was well over 6-7 years old WITHOUT stabilizer in older fuel injection cars that have sat for years. Not to mention generators etc. Diesel is a whole other story and can last for 15+ years.

I think what you posted twinskrewd was UK laws. Even if it is US guidelines... Who cares?

FEMA states that people should store 32 gallons of gas, along with the 5-6 gallons in a generator for emergency operations. This is highly advised for people up north where snow and ice can cripple the electrical grid and also in coastal regions.

Getting back on subject.

Try and get an 87 octane tune from your tuner, he will probably just bump the timing way down and won't charge hardly anything. Store 93 octane gas with stabilizer, and try and keep your tank halfway full at all times. ROTATE your gas storage every 3-4 months or so.

 

Sta-bill works just as good as anything really. I always put a little extra in.

Hell now that I think about it, the gas in my 04 f-150 right now is probably reaching 7-8 months old.

Because I live so close to work, a tank of gas in my F-150 would last nearly 1.5/2 months anyway.

 

I don't care what you say....go ahead and google it, everyone will tell you gas is only good for a few months. Just because you "ran 7 year old gas in a car" doesn't mean the gas was still good. Of course if you mix fresh gas with1/2 tank of old gas you will most likely be ok. But why use 7 year old gas when you KNOW it's going to cause engine problems. Why do you think old carb'd engines run like crap with old gas? It's because of varnish and chemical change within the gas.

 

I never stated it was going to be perfect and not break down, but a vehicle will still run with it in emergency situations.

Lets all go back to "rotation" also...

Seriously, you lost this one give it up.
