  post locked   Does gas go bad?  

My car has been idol for about 10 months, Is the gas in the tank still good? Will it hurt my engine?

Thanks in advance.

10 months should be ok. Put some fuel solvent in anyway now. In the future use a fuel stabilizer for storage as it can go bad on you. What seems to happen is additives can make a gel that can clog things up. Pure gasoline would last years but none is pure,

The only way that ur gas can go bad .. is one of two way ..if it was already defective from the pump you got it at ( unlikly or u wouldnt be able to even leave the gas pump lol, well maybe get a block and everything would start malfunctioning on your carLaugh) or if say you left the gas cap open on your car for the ten months and something got in your gas tank .. it just needs to be left running for a while .. let it blow out all the junk that is stuck on your engine .. and figuar out all the timing of your fuel pump again .your engine is all about timming and mixture .. from pistons to your tires. if things arnt mixed properly your cars computers trips out !!

Aggree and disaggree again: Gas if it was pure disilate is stable. The additives used aren't for sure. They can separate like salad dressing over time. You can peel the skin off of old gas that used certain additives or some make jelly that will clog any filter! It varies by what was used for additives that we really don't get told much about at the pumps,

gas will start deteriorating after about 6 months if there is no fuel stable
in the tank basically starts turning into varnish thats good to use on wood
but bad for (fuel pumps ,relays ,and especially fuel injectores )

if its running good for you just drive it next fill up put in some premuim
and hopefully youl be ok

Go buy a can of SeaFoam. It's good stuff. Add it to your gas tank then go fill it up and add more SeaFoam as directed on the can 1oz per gallon of gas I recall.

Seafoam is a carbon and gum cutter. It will do nothing to stabilize stale fuel.

SeaFoam claims to be a fuel Stabilizer...... Every spring my motorcycle use to run rough till I started putting SeaFoam in the tank when I put the bike in storage...... haven't had the problem since. SeaFoam is a fuel stabilizer.

Fuel stabilizers are designed to prevent stale fuel. Nothing can correct it once it's stale.

When I was in the Air Force, my car sat for over a year one time and it started, but ran rough till I got fresh gas and added fuel system cleaner (don't remember the brand now.). I'm thinking about the 10 months in the initial post..... And I just went a little further than the post before mine, with the addition of SeaFoam.

What is in the fuel we buy varies greatly state by state. Fuel does go bad - period at least with the junk they put in it here,

yup fuel will start going bad right after 45 days after
you fill up and yes turn into varnish after a few months
thats why any time i store any of my cars for a few
months if im away i will use a bottle of "stable" fuel
stabilizer and run the engine oh about 15 minutes

for it to really circulate throuh out the fuel system
its great stuff at preserving the fuel in the tank
stable preserves and keeps gasoline fresh for
up to a year! so its well worth doing
now if you dont use any kind of fuel stabilizer while

it sits for extended period i can gaurante you you will have expensive problems.
