Do sealed cans of gas line anti-freeze go bad?

Question

I'm cleaning out a closet and came across two 12 oz. cans of gas line anti-freeze that could be 20-40 years old. Cans look brand new.

Treat as hazardous waste, or put into my trucks fuel tank?

Thanks.

Answer 1

They're good. If anything they are more, not less useful.

Answer 2

Most commercial gas line antifreeze products from the 60's and 70's were mostly Methanol/Ethanol compounds and some had trace detergents. The alcohols in a sealed container would never degrade but the other compounds might. Burning '70's tech in a 21st century engine might not be a good idea. It's 2 12 oz cans that might have run $.89 at the time. Not worth the possibilities. Dispose of them as hazmat.

Answer 3

I won't put it into your truck because "if" it is 20-40 years old the chemical compound can degrade over time even if it is sealed.
I would look for a phone number on the can and call the company they can tell you the age by the lot numbers on the can.

For the max $10 that the two cans cost you could be damaging your car and having to spend alot more to repair it.

Good luck
and if you are going to dispose of it then please do treat it as hazardous waste as you stated above:)

P.S. - JD "working at Walmart" doesn't exactly give someone a whole lot of confidence in your opinion :P

Answer 4

For the money involved I'd treat it as hazard -type waste. If it is isopropyl alcohol and your a penny pincher use it to wipe down electrical contact points. Its no good for cleaning grease. As the other gal said some can collecter would pay an outrageous price for something like that. Be careful with ebay as you'll need to take extreme caution or complete refusal from UPS, US Mail Fed Ex to send something as volitle as gas-line antifreeze in the mail.

Answer 5

eliminate the tank and carefully drain it. replaced into there any water interior the gas you drained from the carbs? If no longer, you have not got a moisture difficulty. possibly you basically ought to do a track-up, or a carburetor rebuild. after all, the motorcycle is 24 years previous.

Answer 6

i don't know that they go bad, but probably the chemical formulas have improved over the years and you might be better off getting new stuff at the store. you could always put it on ebay as a collector item

Answer 7

I'm sure the chemical make up would not remain stable for that long...besides the newer stuff is more technologically advanced.....get rid of it safely and spring for some modern stuff if you really need it!!!

Answer 8

yes they do ,they do have a limited shelf life,so id think id treat them as hazardous waste and do away with them properly.like any other chemical they will loose their strength after a while,they need to be done away with,good luck on it.

Answer 9

I work at Wal-Mart. They are good.
