I'm told that my Ryobi seized up due to no oil in the fuel. I can't believe it. Is there a way I can check the fuel I have left to tell for sure?

Most mix oils have color to them.  Some maybe green, blue and so on.  Check the fuel you have for color.  If there is none it maybe raw fuel.

Feel it. Put some on your hands. Gas will evaporate, as you know, gas with oil in it is real easy to tell. What that doesn't tell you though, is how much oil is in it.

Thanks for the advice. I was thinking of comparing raw gas with the suspect gas by putting each in a glass container and comparing color. I thought there might be some simple analysis tool that dealers might have.

The simple tool is a kleenex.

Marshall's statement is correct. Please put some on your fingers, it should be easy to tell if there is oil in the gas.

I suggested the kleenex trick for a reason.  Guy/gal comes into repair shop (seen this happen many times) saw/trimmer won't start.  Upon tear down you find scored/scuffed/seized piston.  Guy/gal swears up and down that he/she was using mixed oil.  Dump the gas tank and sure enough - the gas is mixed.  But being the astute mechanic that you are you grab the screwdriver and head for the carb.  Since the machine would not run the only proof is going to be the gas left in that carb.  How to get it out with out wasting it?  Use a kleenex or paper towel.

Sherri, What is the kleenex trick. What do I do and look for? Jonathan

pull the carb and dump any remaining fuel out onto a clean white tissue so you can see the color of the fuel to determine if it was indeed premix or straight gas. it wont tell if the premix was the right ratio, but at least will help determine if the fuel was mixed or straight gas

OK. Thanks alot.

Jonathan,
You can also use a piece of white paper too give you a comparative.
Put one drop of the mix you have in the unit on the paper.
Put one drop of "straight gas" next too that.
Put one drop of known good mix next too that.
Let them dry for a few minutes.....The darker the spots.....the more oil was present in the mix.
There are other reasons for seizures.
