I will not readily disagree with someone called Contumacious
But I do have a few worries...
My experience is that recanning ink tends to shorten its "use-by" date. If you have mixed it with a little plate oil to loosen it, the mass of the oil has been exposed to oxygen, and a drying-oil has been added to it. I suspect it will start to polymerize more rapidly from now on... I mean, not overnight, but possibly it will glug up within a year or two. I'd use it ASAP. I've received some old cans of ink, cleaned them up and recanned them, sealed the cans etc, and found them all skinned and very dry two years later, so they can turn on you!!!!
Just my opinion, based more on vague and general recollections than rigorous scientific analysis
all the best!!!
