The guy I am helping with TA/D has a oil deal with redline oil. He change oil every pass and throw 14 qt. away well was. I have been getting it for last cpl races. Very little if any alcohol in it. I have filtered it and wondering best way to insure zero alky. Have not seen any signs of alky even after sitting a month and half. Have heard heating it and letting alky evaporate removes it. Have stuff to do,but wondering if other or better way. Only have 35 gallons so far.LOL

We have used a big pot on a hot plate.
No open flame.

Yea Iwas expecting alky on bottom but after sitting did not see ANY. Just wanting to insure as best possible. After all even atg 56 bucks a gallon and costing nothing its not cheap if cause problems,Seriously doubt it will.

I use an old crock pot...cheap garage sale item. Get it up to 170 or so and the alky will bubble out. While it is HOT I run it thru a very fine screen into a clean container. Still flows slow but if it wasn't hot it would probably take a week!!!

When i did it, i bought an inexpensive Walmart soup pot, and a used hot plate (no flame). i kept it about 150* until the fuel was gone. Worked great. Filter and pour back in while @ that temp, or like Steve says, it'll take forever lol

When I tried cooking it it seemed to take forever but it worked.
When refrigeration guys install refrigerant lines they pull a vacuum on them to remove the moisture. And it takes a while.
I wonder if that would work with the oil in say a pressure cooker pot? Something that wouldn't cave in under vacuum.
It would remove the risk of fire if it would work.

I use an old propane tank welded to an old flexplate so it doesn't fall over and strap a Moroso heat pad on. Does not work with nitro because the boiling point, I just let it settle a few weeks and drain off the bottom quart or so until clear. The attached picture shows what happens to the different fuels and mixes. The 3 VR1 samples were shaken vigorously and allowed to settle, the Brad Penn 40% was used in my engine with 3 passes on it. Looks very similar to the 45% sample.

Now f you could recycle the nitro.LOL

When you think about it, you’re effectively building a moonshine still. And I have ..um... allegedly run one once or twice...
As you heat the mixture you will watch the liquid temp rise gradually but the air temp in the line arm will stay room temp and then all of a sudden go right to the boiling point of methanol, at this point you turn on the water to your condenser and viola-methanol starts dripping out. Methanol has a lower boiling point than ethanol (149vs173) and is the stuff that makes you go blind from lousy moonshiners.
The boil will stay at this temp until the methanol is gone and then all of a sudden jump up to the next phase change, the boiling point of ethanol and then eventually water.
In theory if you had a tall reflux column still you could probably save the nitro.
Otherwise a centrifuge would probably work too...
