Yeah I buy at the .99 store and the saw takes about 7 gal and I buy 3 changes so pretty much clean the shelves and I get a lot of look.  Big baby what can I say.
Makes it about 12.00 a gal. of course now with the stp divide another 6.00 divided over the 7 gal.  Really hate the smell of STP.  I use gloves always so better to have nasty oil you don't touch to cleaner oil you breathe

If you are getting mist, something is wrong.  My big saw has double feeds at the back of the blade and has no mist at all with mineral oil.  Also no mist in smaller saws with dip feed.  Oil will mist when it gets hot.  That can happen with too little oil or with friction from misalignment or excess pressure.  Too much force is unlikely unless you are having trouble with jamming.  The most obvious indication of misalignment is saw marks on the finished cut.  In time you will have a dished blade.

Hi All

Fuels Oil No.5 Heavy   160 - 250
Fuels Oil No.6   150
Gasoline   -45
Gear oil   375 - 580
Iso-Butane   -117
Iso-Pentane   less than -60

I dont think you need to worry about the flash point.

I am using the original blade that comes with the saw and getting precise cuts that look polished when coming off the saw.  I dress the blade regularly and the saw only has 3 feed speeds and I am on the slowest speed since I seldom cut softer stones.  I can cut 1/16 slices so I think that the saw is true and feed is correct.  I am assuming that it is a factor of using Baby Oil.  Since the Baby Oil is meant for skin absorption I am assuming that it is simply too thin or incapable of dispersing the heat in the oil from cutting.  I am putting a bit over 7 gallons in the saw so it has plenty of pickup area as the blade is sitting in 3/4" of oil.

I do remember that my friend that suggested the Baby Oil also commented on the mist and rolls his saw onto the driveway when cutting so the air disperses the mist.

I also use Walmart baby oil.  It is pure mineral oil with oderant.  3/4" is a bit deep.  I wonder if it may be churning too much.  I generally try for 3/8".  I think I would also experiment with more speed.  I've never noticed it with light pressure, but who knows.  I'm sure you have tried fresh oil.  I'm kind of out of ideas, but rest assured, mist is not normal.  Hopefully someone has other avenues of approach.

I get a little misting in my 24" saw using rock cutting mineral oil. when I am cutting large hard rock. (I could be cutting 50 to 70 lb rock for spheres) the saw has a very slow speed on the drive. and it holds 15 gal of oil.
if you cut some of the California clear creek jadeite it could mist just about any saw oil. That stuff dose not like to be cut!

I use a varying mixture of horse laxative (mineral oil) and human laxative (slightly heavier mineral oils) and have virtually no misting problem in my 12" saw.  I agree with slabbercabber, if you have that much misting, there is something else wrong and potentially the major culprit would be too much oil depth.
I tried Baby oil (it was no cheaper than the human mineral oil laxative, and it stunk like a baby and appeared to be thinner as I recall).  Nothing tempted me to switch, so I remain firmly in the laxative camp.  Tom

I would be in the Laxetive Oil camp too however in Ventura County CA I have tried local feed stores but this isn't the best area for a good farm supply.  I haven't tried looking online for the laxative.  Maybe next time thru NM I might have to stop at a feed store or maybe even a Tractor Supply store I think they are named.

It seems most of us have tried a few different oils.

Most replies are for baby oil or light mineral oil either human grade or animal.

My base oil is human grade (purchased at a local fuel/oil depot) with a heavier additive to settle the mud.

I cleaned my clubs saw yesterday 14", it is straight human grade mineral oil, the oil was thick with mud only a proportion had settled, my saw I have twice as much settling.

I am a beer home brewer (over 200 over the years) in that I put finings (some are fish extract) in the beer to settle the sediment before bottling.

I suppose I am looking for something that works at removing sediment from light mineral oils. 

[irockhound]

I have noticed that since adding the bottle of stp oil treatment the grindings are falling out of the oil better. I experienced the same issue as your shop, straight baby oil and the grindings suspend in the oil and it makes me clean the saw more often.

If anyone has an on line source for the other mineral oils let me know and maybe the average cost per gal.
