fuel disposal
 

I have about 70 gals. of 2 yr. old gas in my tank.What is the best way to drain it , and then what to do with it ?

Re: fuel disposal
 

I picked up a 55 gal HDPE drum from a local feed store and drained my tanks by gravity. Our county has a toxic waste disposal site that accepts stale gas. Yours might too. If it's gone to varnish, don't even think about running it through an engine. I made the mistake of trying to burn some in my generator and had to pull the engine apart to get the valves unstuck. What a mess.

After Moving Way up North (Melbourne,Fl) I had 50 Gal. of gas for about 2+ years. It had Oil, Additive etc mixed. It burned,smelled good (No Varnish) etc.Couldn't find a way or Place to get rid of it.. Placed a ad on Craigslist & explained everything, Fellow showed up w/ containers for Half next few days came & got the Rest. He said the size of His Tank Mixed He didn't care.. Easiest I've found Just let em' Know it is Old. (Was Not Ethanol). Good Luck!

WILSON , I have a new twist to the story today . If I can rem. how to post a pic , you won't believe what I found when I removed the filter late last night. Yhe top of the filter is covered in what looks like uncooked grits . white , tan dark brown perfectly dryed crusty BS
I have never seen anything like it.!!!

Re: fuel disposal
 

I used up some 2 year old gas in my ole Dodge truck.
Dumped 6 gallons at time in when I would go to fill up..
It even had TCW 2 or 3 in it...
Trucks valves had never been cleaner! :)
This was many years ago when the truck had 50,000
miles on it. Today she has 285,000 and still going strong.

See ya, Ken

WWP2, if I were u, I'd invest in a cheap electric fuel pump...pump it out and run 5-6 gallons in my truck...thats what I normally do with old fuel.....mixing it with a fresh tank. If you dont want to do that...I'll run up that way sometime and pump it out and burn it for ya! Let me know what you think.

Re: fuel disposal
 

Previous to my restoration,my Tsunami sat in a field for six years with about 45 gallons of gas in the tank
We siphoned it out and guys at work put it in their pickup trucks and tractors.
None of them had any problems with it.They were more than happy to get free gasoline.
I,on the other hand didn't dare try it.I was just happy to get rid of it.

Re: fuel disposal
 

I'm the poster to this thread originally .An update , I drained the gas and it looked and smelled just like some fresh gas that I had. I mixed about 10 gals in my truck tank with 7 gals of gas already in the truck .What a F - up
The truck cranked and drove for about 2 mins . It spits , jumps ,coughs and every other noise you can think of.It will not continue to run when you put it in gear .I am an Idiot , my wife laughs at me , This really sucks

Re: fuel disposal
 

Bummer! How many more gallons will your tank hold? Maybe change your inline fuel filter a time or 2 (I assume truck has one) Then either drain the tank or top it off with high octane or pour in some octane booster). Hopefully the sediment in the old gas just clogged up the little filter and it clears up some by changing the filter.

10:7 bad gasoline ratio was maybe a little extreme...hope it gets right for you. Good luck.

Yeah, did the same thing when I was a teenager with my car. But I had 300 gallons of 4 year-old gas out of my grandfather's Rybovich. Here's what my grandfather had me do: I went out and purchased a gallon of pure grain rubbing alcohol and a quart of naptha, and mix them into a 5 gallon jerry can with fresh gas, then pour that into the tank of my '66 Olds 442. I pulled the carb and cleaned it out with Gumout, then back-flushed the fuel lines with Gumout. Then I installed a Mercruiser water-separating fuel filter on the firewall, and ran the fuel line through it. I then mixed ten gallons of grain alcohol and 2 gallons of naptha into the remaining 280 gallons of gas.

My grandfather said he learned that trick back in the early days of WWII when the gas being distributed to civilians in the Keys was often the old military stock-piled stuff, which the Navy got rid of in favor of the new higher-octane gas. JFTR, I burned the rest of that old gas without a hiccup afterwards. (Of course, 97% pure grain alcohol - that's ethanol based, not isopropyl which may be methanol - could be purchased from the Rite-Aid drugstore back then for only 70 cents a gallon)

Or you could try this.

What is Star Tron® and How Does It Work?

Star Tron® is a revolutionary multifunctional fuel treatment based on naturally-occurring enzymes. While this is a unique application of enzyme technology, we encounter various enzymes in our everyday lives. For example, enzymes in laundry detergents break down dirt and stains so that they may be easily washed away, even in cold water. Enzymes in the human digestive system break down food into components that are easily used by the body to produce energy. Functioning as biocatalysts, enzymes increase and control the rate of chemical reactions. Star Tron® uses highly specialized enzymes to modify how gasoline and diesel fuel burns, resulting in more complete and uniform combustion with reduced engine emissions. This same enzyme package breaks down fuel sludge and allows water to be dispersed throughout the fuel as sub-micron sized droplets that can be eliminated as the engine operates while also cleaning the entire fuel delivery system. Contaminants are either safely burned off or filtered out, and fuel chemistry is stabilized for long-term storage.

Star Tron® is not affected by and does not affect any fuel treatment that may already be in use. There is no possibility of any negative chemical interaction. Because Star Tron® is pure fuel, it cannot be over-dosed. It is formulated for use in all 2 and 4-cycle gasoline engines and in all diesel engines.

My outboard mechanic told me about Star Tron yesterday. He said it is what Yamaha is recommending now.

Re: fuel disposal
 

Star Tron is >95% petroleum naptha, plus .5% organic aldehyde and ketone reactants (makes it hydrophilic) Aldehydes, for those of you who remember high school chemistry, are alcohol molecules.

So I guess this should be OK in a Bloody Mary... :D :D :D

Re: fuel disposal
 

no , alcohols are compounds . grain , isopropyl , methanol ,
Fr. Frank you are too much . I took 18 months pre-med back in '77 , it's funny how you can remember things you have not used in 30 + years. And to think my Seacraft is from the same time period .

Re: fuel disposal
 

Yeah, but I'm glad there are people around to correct me when I get stuff wrong. (Especially in church) :D

Re: fuel disposal
 

it's strange how you work on a certain problem and by the time you get every thing put back together , something the was working perfectly will screw up .I drained all the fuel out of my front tank which has never leaked , the minute I put 10 new gallons of gas and a can of seafoam in , I have a leak draining to the bilge and running out the back. So I dug out the jimmy rigged cover over the front tank , it was the area in front of the seat .23 SF 1978 . The whole cover needs to be rebuilt .It is the hinged type . We had someone put the tank in and he took major shortcuts .Should I rebuild the hatches with marine plywood or some type newer materials?
