Got a gallon or two "donation" of blue Valcool (a Valenite product, I just learned), so ahm sorta set for a while.
But here's what ahm learnin:
The dilution ratios for various oils varies *widely*, from 6:1 to 35:1, from what I've seen. My local suppliers carry Rustlick, whose WS5050 oil they say supports dilution ratios from 8:1 to 35:1 ! But read further....
I was under but another mis-impression that 30:1 was the "standard" dilution--mebbe that was just the Silogram stuff (Brooklyn, NY) that we used to use. Valcool specifies 15:1 to 25:1 on their label. The dilutions supposedly correspond to light-duty, heavy-duty use.
But the plot thickens:
So now, I just got off the phone w/ Rustlick, and man, the info these local suppliers have is way off--no surprise, eh? The WS5050 supports 15:1, 20:1, mebbe 25:1 for light cutting of aluminum. Has rust stuff/bacteria stuff in it, altho not for rarely-used tanks w/ lots of tramp oil on top. The rustlick guy said 8:1 and 35:1 is impossible for their WS5050. Also, the rustlick label gives the refractometer data for various dilutions.
So apropo of previous threads on solubles and refractometers, how does one*know* what the right dilution is, for a product that has fairly wide ranges?
Apropo of my earlier assertion of sol.oil's digestibility, Valcool contains amines, and the label says def'ly do not ingest it. May indeed be digestible, but still not good in coffee...
Also, the con. Valcool is, according to the label, perty dicey stuff, a "primary" irritant of skin and eyes.
Has anyone used or have an opinion on Rustlick, distributed by Turpin?
Two diff local suppliers carry *only* Rustlick in-house! Traverse tools in Queens, and Westchester Tools, in, of all places Yankas--cheaper too: $20/gal, $83/5 gal. Traverse is apparently a Fortune 500 wannabee, while West. tools is smaller, but has/can get lots of stuff, perty cheap, nice place. I think Traverse recently put up 2" thick Lexan, like what banks have. Gimmeafuknbreak...
