glow fuel

       Remove this ad - become a site supporter!
I was wondering how long glow fuel stays good. I have 2/3 of a jug full of cool power 10% . I think it's 3 seasons old.

Thanks for any advise.

Re: glow fuel

Right from there website,

"Unopened and stored in ideal conditions (between 60-80 degrees) it will remain usable for several (5-7) years. As the fuel begins to degrade it will increasingly lack the punch of new fuel. Really the only way to tell if the fuel is good is to run it. If it idles well and the transition is good on the ground, use it. You might notice a little less "bark" in a fuel that has been stored for several years but it won't hurt the engine.

Opened would vary according to how much moisture the fuel has sponged out of the air. A quick way to ruin a gallon of fuel is to drain your tank at the end of your flying day back into the fuel jug. What is happening is that your fuel is picking up moisture from the pressurized tank. The carburetor is sucking in humid air and after combustion the moisture laden air is entering into your tank via the tube from your muffler. When you return the fuel from your tank to your fuel jug you are contaminating the rest of the fuel in the jug.

My recommendation is to run your tank dry at the end of the day, but whether you do that or not don't return the fuel from your tank to your fuel jug."

Re: glow fuel

2/3 jug 3 seasons old is most likely contaminated with moisture.

How much is impossible to say. In any case, moisture is the enemy.

Some engines are more tolerant to old fuel than others. I had an OS 1.08 that would run fine on any old weasel snot you could dump into it. No way with my Super Tigre 2500, which will not operate properly on anything but fresh fuel with the proper oil content.

My oldest glow fuel was mixed with the gasoline for my weed whacker and lawnmower. It really helped their high end performance. Those babies really spool up on glow fuel.

Re: glow fuel

Rejuvenation pellets: I bought some pellets off ebay from Funship Models in Florida, From the data sheet "Molecular Sieves 1/16" Type 3A". I bought some stuff off a guy and with it came half a gallon of 5% fuel. It had some stuff floating around in it and it did not look just right. I put a small wad of polly-ester pillow stuffing in the bottom of my funnel and pored it through a couple of times. I put in some of these beads and left it a month. It was clean and looked a lot better. I tried it on a couple of engines designed to run on 5% or less nitro and it worked perfect. I suspect that it is the same stuff that they put in snow machines and personal water craft to absorb water, it comes in a little plastic screened container that you drop in your fuel tank.

Re: glow fuel

Wow, it will probably have a little more water in than a new gallon but definitely try running it first. If it runs through a tank on the ground with no problem it will be fine in the air.
If the fuel is not reliable then keep it for cleaning engines, flushing carbs, or breaking in engines..

Sure are lots of myths that won,t die .And this is one of them . If the fuel was sealed , it,s GOOD ........................PERIOD

Re: glow fuel

Here is the text of an earlier post I made on this topic:

My son gave me a PARTIAL (3/4) jug of fuel he had sitting around. It had the internal plastic cap in place, and the outer screw cap on it. It had been stored in his garden shed where it gets very hot in the summer. So hot that the bottle was venting fumes past the seals. When it cooled off, the inner seal reseated and the bottle partially collapsed on itself. It sat there for at least six years.

I put it in my engines and used it all. Ran just fine, thank you very much. Saved me about 15 bux on fuel!
