99.9% of the sugar settles or is filtered out, big shops have fantastic filtration to meet FDA for reusing oil.
That sounds great! I am hopeful this will work. I'm not too worried about sugar because I believe they aren't glazed until after the frying. And the sugar shouldn't go into solution in the oil so should filter out.

best sources

I have found the best sources of oil to be Greek or Sushi places. They don't abuse their oil because it would make their food unpalatable. In my experience starting with the best feedstock possible yields the best fuel with the least processing problems. Cheers Dan

Most old fashioned donut shops use fully hydrogenated oil that is solid at room temp. Not good for bio use

From what I've read the hydrogenated oils make good, high cetane biodiesel, but it gels as warmer temps that the non hydrogenated oils. So it makes good summer biodiesel, but not good winter biodiesel.

It's cheating, but in a pinch, you can add a teaspoon of real turpentine to a 5 gallon can of diesel fuel or biodiesel and it will raise the cetane level several points.

I found this out years ago from an old Russian truck driver who used to fix GaZ trucks in the former DDR.

Where in the world did you find olive oil for $3 a gallon? I make soap and would LOVE to find a source like that!

I do not know if Krispy Kreme is old fashioned or not....but no use asking for the left overs of whatever they use..... they have NO LEFTOVERS... it goes out IN the Doughnuts...
