Alcohol with Ink in it ...?

I work at a plastic sheeting type facility and we have drums of used propyl alcohol with ink/pigment used for printing in it. Any thoughts on filtering, using this ?

Note: It's 99% alcohol when the drum is first opened.


Obviously mixed with some oil etc.

I would be worried about moisture is might have absorbed from the air.

Throw away the alcohol and run the oil.

isn't alcohol not good for engines?

Its molecular size makes it burn twice the amount, as an alchahol molecule is half the size of a gas molecule, also its hard on rubber parts in carbs and fuel systems. Also theres zero lubrication properties with it, but yea it'll burn, the exhaust fumes also make your eyes water or (burn). But for free, Id take a chance on the H2O comtamination, if it was stored indoors the likleyhood of comtamination is small. The ink might make a slight bit of carbon, I doubt it will make much difference if as you say it was 99% on the lable, thats beter odds than most gas stations.

throw some WMO in the tank with it for lube

I'd definitely add a lot of oil to it, and its free

I'll see if I can get some specs on the ink that's in it and in what proportions and post it up here.
