I recently came across approx. 20 gallons of old gas. 5 gallons came to me in an old gas can someone was throwing away. I saw it at the curb and stopped. The can had gas in it but the spout was broken. I fixed this problem by removing the gas cap from an old mower that was also being trashed and went on my way with the can full of gas. I don’t know how old it is but it doesn’t smell super fresh. It also doesn’t have the completely broken down smell of really old nasty gas. I don’t know how to describe that smell but it in no way resembles the smell of gasoline. It is a nasty dead smell.
The second 15 gallons are so came out of a vehicle I am getting ready to part out. It has been sitting a little over a year so I siphoned it into cans. The tank was full and the gas is darker than normal but still smells pretty much like normal gas much like the gas in the can. The smell isn’t like that of fresh gas but it doesn’t have that dead smell either.
I have been mixing this gas with that for my lawn mowers and using it up slowly that way. I have also put up to 20% in a truck that I plan to change the fuel filter on soon. I figure the rest of the fresh gas will dilute this and keep anything from getting gummed up.
Also, I sometimes come across totally dead gas that is completely broken down and has that horrid stench. I wouldn’t put this in anything no matter how diluted it might be so I usually just put it in a pan and burn it off or use it to help burn off brush.
Does anyone have a better way to get rid of old gas or am I doing the best thing?
