I volunteered to mow this womans yard(with her mower)& the gas in the carb bowl was like dark brown tea & no go until I flushed it & it had only sat over the winter(~4 months).I was surprised it went bad that quick.

Along the same subject -- What is the best way to get all the gas out of a tank on our old cars?
A Siphon kit from the auto parts store? How can you be sure you got all the old gas out?
I have a car stored that I'd like to drain out before adding some new gas to, also.
Thanks!

I suspended a small gas can to feed the carb & ran the fuel pump into a barrel & drained the tank that way then added several more gallons,swished it around & pumped it out also. I've used those cheap parts house siphons & they never work right. A siphon or hose might get to the very bottom of the tank but after swishing/draining the extra gas I was comfortable.

How can you tell if the gas is "non-oxygenated" ?
Is it mainly by smell? I'm a little concerned about a car I have some older gas in ... but I couldn't smell anything abnormal when I took off the gas cap recently.
And if I pump out the old gas and it is bad ... should it look different?
Thanks for any tips!

You can tell by getting it from a pump that says "non-oxygenated" on it. Seriously, it is just the premium fuel with no ethanol in it. Maybe other parts of the country are different but that is how it is done in Minnesota. The blend fuels seem to deteriorate rapidly because of the ethanol in them. If there is an obvious bad smell or appearance, then I would not use it, at least not in something I care about.

Ok, thanks for the explanation! I had not heard that term before. I'm in California, so will check this weekend when I go to the pump.
If I think I might have run some older gas (year or two) through my car recently, is there anything I can do to head off trouble? Like adding a fuel additive, such as Gumout, STP, etc?
Thanks!

Ok, thanks for the clarification on that. I usually learn more from these postings than from reading the newspaper! Have any of you guys tried products like Gumout, etc Fuel System Cleaners? Does this stuff have any real benefit to our classic Mopar's fuel system? Does it cause any harm? Thanks!

Most gasoline fuels are blended for an average shelf life of three months. Ethanol attracts water and that does not help, so the humidity in your area can have an effect, YMMV. Stabil works pretty well. I have found that old fuel gets a varnish smell to it, and at that point, I would drain it. Setting a car up for storage means draining all fuel or at the least, adding a stabilizer and topping off the tank so there is no room for condensation to develop.

I pumped out 15 or so gallons out of a Truck tank and ran it in my '88 TBI-Injected daily driver D-100. Ran fine. The gas didnt smell bad or anything, smelled like gasoline.

I just syphoed out about 5 gallons of old gas and to get read of it I put it out side in 2 big open pans and about 2 or 3 weeks later it was all evaporated away totally ,,,,,,,,, on the rainy days I put a sheet of plywood over it seemed to work good for me but I was real nervous that somebody might flick a cigerette and start a inferno real glad its all gone its hard to get rid of old gas cause nobody in my area will take it.......
