nidom Posted May 26, 2010 Report Share Posted May 26, 2010 I always put any old or unknown fuel to one side and use it to clean chains etc, or bung it in the lawn mower. Quote Link to comment Share on other sites More sharing options...
timp Posted May 26, 2010 Report Share Posted May 26, 2010 I would just buy more fuel, mix it with 2 stroke oil at a slightly higher rate than normal and then add some of your original fuel at about 25% of the total. Might take a while to use it all but is a pretty safe way. Quote Link to comment Share on other sites More sharing options...

1oldbanjo Posted May 27, 2010 Report Share Posted May 27, 2010 In order to avoid this situation I have two things that I do. One is that I have "mixing tags" that you can attach to you fuel jug and you can switch the tag to show if you have mixed it or not. The second thing I do is that when I have a 2 cycle oil that does not have enough dye in it, I add some. I bought a little bottle of blue dye that is used for dying candles - make sure you get an oil based dye and not a soy based one. It takes about 5 drops of oil per gallon to tint the fuel enough to show vividly that the fuel is mixed. I got the dye from a craft seller on eBay - but any craft shop that deals with candles will have it. Quote Link to comment Share on other sites More sharing options...
motovintage Posted May 27, 2010 Report Share Posted May 27, 2010 use a test paper such as a white paper towel, put drops of known 2 cycle mix, straight gas, and your mystery gas, let the fuel evaporate for abought 1/2 a day and compare the residue left, the 2 cycle mix will leave an oily spot.

OK this is going to seem insane (like much of what I say) but I was wondering what would happen if you dropped a few drops of candle scent into your premix. You know to sort of... freshen up the line at the section start. Quote Link to comment Share on other sites More sharing options...
