How long can you leave it in...?, Before gas goes bad... Options

[sherman1]

OK, minds outta the gutter !

We're talking gasoline in the 914 tank - How long can a 1/4 -1/2 tank of gas sit in the tank, while the car is in storage, or under restoration (whatever) before it turns bad & begins to look like old varnish?

I know I can drain the gas out, into 5 gallon containers, but I wanted to avoid that if possible.

I figured about 4-5 months before it begins to go bad, but not sure.
How about using a gas-additive, or octane boost?
Any gas experts here? (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)


Thanks!

A few months ago I helped dig my parent's '79 Dodge Powerwagon out of its 9 year old spot...

it;s important to note *all* the conditions.

sure, there are stories of old gas lasting. but gas was a lot different - much less volatile - "only" 10 years ago. the current question involves contemporary gasoline.

second - sure - lots of people - including me - successfully store gasoline over the winter in cold climates. a cold climate winter is a far different environment than a summer in California where the original poster is located.

last - 9 years is nowhere close to the record :-) ... my yellow car had almost a full tank when it had its track incident in 1981. when i drained what was left - in 2005 - it was more like varnish and stank quite badly...
