The World would, combined with condense and possible dis-similar metal corrosion. Metals like to find there way back to the earth in the form of oxides. Highly oxidized gasoline helps some as well.

Mine looked like yours in my mustang. I just removed tank and all as I tried to clean the tank on my chevy dump truck with a pressure washer. I couldn't tell I'd even been there. I read some info about putting gravel or nuts and bolts in the tank and sloshing them around. I guess it rubs the corrosion off as it is moved around. You could also seal the stuff in. Since both of mine are more modern I'm just getting new tanks. Fortunately they're both found at a decent price. The tanks of both are sitting in the back of another truck, empty and able to breath outside my shop (will go for scrap). If you get anywhere close you can still smell that old gas.

If I leave gas in my mower over the winter, I have trouble starting it in the spring.
I have since learned to drain and runn out during winter storage.

Re: Really old gasoline question
 

none of you fellas ever hear of fuel stabilizer?

Re: Really old gasoline question
 

One more thing to buy that has limited effect. For small engines, it's not worth the money. Here is Texas, it's too hot for any stabilizer to last very long. It will last longer in cooler climates but even the stabilizer only lasts for 2-years setting on the shelf. If you use it, check the date if it has one. It only works for fuel fresh from the pump. If it's already set for two months than no stabilizer will help it. They say that stabilized fuel will last for 24-months but they also have the fine print about the longevity in warmer temperatures and higher humidity environments.

Kurt, My current "daily driver" is a Mercedes 1980 300SD. It is a slow restoration project for me. I figure once I fix it up I will be able to put a few hundred thousand miles on it and might even add a spare fuel tank to switch to/from waste veggie oil.

As for old gas, I give it away to the landscaper. Let him screw up his mower.

Re: Really old gasoline question
 

I guess where I live it works much better. I use it in all things that sit for most of the year. gensets, lawn mowers, ect ect. works well here

Re: Really old gasoline question
 

It's normal for the new CRAP gas to do this kind of damage. That corn crap attracts moisture and corrodes (rusts) things like crazy. At least the new vehicles with plastic gas tanks don't have to worry about rust from the new crap gas. The shelf life is very short with crap gas, so if it's more than about 6 months old, I'd use it to kill weeds or to start my recreational fire.

Re: Really old gasoline question
 

I've seen a couple comments about using stale crap gas to kill weeds. My wife says almost everything in our desert yard qualifies as a weed. I'm hesitant to pour gasoline around as it might get into our ground water. Ideas?

I always have a hard time finding a way to dispose of the
Old fuel . Oil easy old gas not so .

Re: Really old gasoline question
 

Just put it in an old metal bucket and burn it.
If you leave it in an old bucket, it will also just evaporate, but them we will get to smell and breath it.

Re: Really old gasoline question
 

I found out today that our local land fill takes motor oil and crap gas and puts it in barrels to be taken to where they can properly process it. Yay!

Re: Really old gasoline question
 

Or you save it for winter, and you light one of those oil burner heaters. There's some good designs that heat the oil, burn it, and somehow heat & re-burn the gasses left before it goes out the smoke stack. Supposed to be pretty clean & odor free.
