Gasoline and time

[A bones]

Maybe not the right place to ask but, here goes. After years on the interstates and more than five years of bad health, I'm soon to get back my strength and tend to my 'junk' collection. As I look around I realize I have many gallons of gasoline in five different tanks.

Anyone Know the best use of this spoiled product? I've been thinking the Model T might be able to digest it, but I won't find out the hard way. As it won't just disappear, I wonder what if any good use it may be ( not cleaning parts, and not disappearing into the environment ) Thanks for your time and attention.
