Decalin RunUp shelf life?

[dholly]

Seeking some guidance on my first purchase of Decalin RunUp.

For $19.50/16oz. vs. $29.50/32oz., the large size is clearly a better value. However, since it is used rather sparingly, I don't want to run into issues of degradation. Does anyone know what the shelf life of this stuff is? The MSDS (http://decalinchemicals.com/wp-content/uploads/RunUp-MSDS.pdf) offered no clue.

Thanks

I was told by a representative at AirCraft Spruce that it has a long life, even after it begins to turn yellow it can still be on the shelf for over a year and still be good, I personally buy the 16oz as they are easier to carry in the plane on trips and usually use a bottle every 4 months or so.

Thank you BigJohn. To be on the safe side, I will go with the small since it may take me a whole year to go through it. We are actually beginning to see an increase in retail sources carrying ethanol-free premium auto gas around here, good news because those marinas that do sell ethanol-free are generally low octane only. Apparently those boaters are cheap bunch.
