can gas for cars go bad?

Question

for example if you buy gas in 2006 will it still be safe to use in 2007.

Answer 1

I don't know about an actual expiration date, but I believe some of the gas stations now are using gas with a little more oxygen added to the mix. It runs just as good, but I would only suggest you use it if you are taking a long trip, or if you know you'll use it all up soon. Don't get it if you're just going for your monthly fill-up (i.e. you don't drive that much). If you allow it to sit in your car without having put some of that engine protector fluid in with it, it could cause minor problems over time.

Answer 2

some of the more volitile components of gasoline will evaporate or break down fairly quickly, 6 months or so, when the gas is stored in a sealed container. the gas will still burn but may not provide as much power as when new. if it's in a car, just fill the tank with fresh gas to blend the old with the new and minimize the effects of the old gas. add a bottle of techron or some other good fuel system cleaner to help. drive the vehicle to run the old fuel out as quickly as possible. there is no need to pay to have the tank dropped and flushed and the old fuel disposed of.

Answer 3

As mentioned, you will need to use Fuel Stabilizer. This needs to be added when you buy the gas, "not" weeks or months later. Also, read on the Stabilizer, it only considered good for a certain amount of time (one year). Though it may last longer.

Answer 4

Yes, it can get "stale" if it just sits...you mean from lawn mowers and such? Over a winter it can leave deposits in the carb too...in a car, if the car sits for a long time, you should change all fluids too...

Answer 5

you can use fuel stablizer, but it only keeps gas good for a while, fuel does go bad it will start shalack, , use it asap,
