I've decided to switch to mineral oil for my big saw and wondered if anyone has used Walmart mineral oil? You have to buy it by the pint and it runs about $12/gallon. It is the cheapest I can find that I can transport by myself. I was told that there is a local (within an hour's drive) that sells a food grade mineral oil by Chevron, but you have to buy a 55 gallon drum. Unless I put a motor, tires, and steering wheel on it, I'm not getting it home by myself!

I've bought about 2 gallons of it (you should've seen the looks I got <<<snort>>>>).

I've also heard that you can get some at a feed store (sold as horse laxative), but haven't looked at our local place.

Hello Mary Ann,

  If you look in your local "Yellow-Pages" under Oils-Lubricating you may find a supplier that sell it in 5 gal buckets, most of them here in Salt Lake do.  That's how I buy mine.  Many of these companies call themselves "Petroleum company" and they deal in many other forms of oil as well.
  A couple of phone calls may help you save a buck or two.....

Thanks! I just tried that and found a possible source. However, they stumped me by asking what viscosity. They said it comes in a range of 20-150??? A rock club I visited uses mineral oil and it seemed quite light. My guess is I might want it in the lower viscosity range?

The supplier just called me back, he had done some investigating for me. He recommended Schaeffer food grade oil, viscosity of 32. He said it is a high-grade oil. He said he also had some non-food grade (Chevron rock oil and Superla) that is not as expensive. The Schaeffer food grade is $92.71 for 5 gallons.  omg

Lighter viscosity is better. I am unsure what scale your viscosity numbers are in. there are 3 or more scales in use. The one I know is SUS, and a "light" mineral oil is between 65-75 SUS. For example, water has a viscosity of 31 SUS at room temperature, whereas vegetable oil has a viscosity of 200 SUS at room temperature I have been buying STE-70 mail order from Texas, but it is $19 plus shipping, and this time around, I got the light mineral oil from Farm Tractor Supply for $15. It seems close to SUS 70.

The other characteristic is flash point, where higher is better. STE-70 is about 388 deg-F.

Thanks Daniel,
I have no idea what the scale is, I'll have to ask when I go there. The guy was really  nice, trying to save me money with the non-food grade, but he said there was an odor. I want to go to odorless. Does what you use have an odor?

The oil he suggested for food grade is used in the valley (by wineries) for high speed machinery.

I use agricultural grade light mineral oil.  It is available at just about any livestock supplier as it is used for intestinal problems in horses and cattle.  It works well, is non-toxic and does not create too much vapor.  I pay between 10 and $12 per gallon depending on the store.

Don't know if this will help or not, but here's a link I found while looking around for information on the Borax thread yesterday.  Also has some info on oil in the comments.

Mary Ann, fwiw...I use hydraulic oil from the 'Carquest' auto parts store.  $35 a gal.  Does not smell...just don't know about long term effects on your skin although I wear gloves most of the time.

The Farm Tractor Supply oil has a faint alcohol smell because of some trace impurities - not really an odor. It it more like technical grade, which is one step below food grade. The STE-70 is avalable in either technicalor food grade, and the only difference is some of the conditions of botteling. No odor.

I found this chart:
http://www.bobistheoilguy.com/visc.html

According to this ISO 32 (Schaffer food grade) is about SUS 175, which is much thicker than you want. Rock particles will not drop out so fast. You would need ISO 12 to be about SUS 70. But be careful because fo SUS people have to say which temperture it is at.

From another source:  "white mineral oil that is USP grade (US Pharmacopeia) or a food grade oil. The only difference between a USP grade white oil, and a food grade is the requirement for food grade to be packaged in a clean room. They both come out of the same tank. If you have a large bakery near you, that could be a good source for small quantities of these oils. The bakeries use them as a dough divider oil, and to oil the baking pans. Duoprime White Mineral Oil 70, is a 70 SUS odor free oil with a flash point of 330║ F available from Vanguard Distributing. Exxon markets white mineral oils as Marcol 52, and Marcol 82. The numbers indicate the SUS viscosity. They also have a 330║ F flash point. There are many more white mineral oils available then just these two. All of the white mineral oils clean off slabs easily as well as from your hands."  Thanks woody

I did find a couple places on the internet...
Had shipping calculate to me (same zip code) for comparison:

Mineral Oil 5 Gallon Pail  -  Price: $ 76.90  (UPS groung $33.47 to me @ Lincoln, NE)
http://www.chemistrystore.com/Mineral_Oil-Mineral_Oil_5_Gallons.html

Mineral Oil 5 Gallon Pail  -  Price: $ 64.95   (UPS groung $28.20 to me @ Lincoln, NE)
http://www.thecandlemakersstore.com/product/ADMO1LB/Mineral-Oil-1-pound-to-5-gallon-pricing.html

There was a site that had "free" shipping and 5 gal to 55 gal but more than 2x the price - so not a great deal.

All great information everyone, thanks! Over the weekend I visited a rock club tailgate sale about 1 1/2 hours away. They used mineral oil in their 16". When I first saw it I thought it was water it was so light. I'm going to email and find out what type they use. The person running the shop that day wasn't sure.

I stopped by the farm supply and was told that they only carry mineral oil during the fair (in August) so I guess not much call for it here. Too bad it isn't used to grow grapes or it would be everywhere! The person working that day couldn't tell me what the price was.

I've got a few leads thanks to you folks, I'll let you know what I end up getting and how it works. I'll be glad to get rid of the smell, but more importantly what I'm using now (Pella) irritates my throat something fierce. It isn't the rock dust or mist, just the stuff right out of the bucket irritates my throat in about a minute of breathing it.

Yeah, they use it for their equipment. That is the Schaeffer food grade I mentioned that Daniel said would be too thick.

That Maracol 52 would be the lightest mineral oil I have heard of.

I can't find anywhere to buy it though. Anybody know?

seeing - "FDA Approved,Medicinal grade white oil.Manufactured to exceed the purity requirements of the Pharmacopoeias"  I'll bet this is expensive.  Only found one site that has 'buy me' options (it's in the UK)...
http://www.lubricantsupplies.co.uk/esso-marcol-52-x-175-kgs.html

Esso Marcol 52 x 175 kgs  (my metric isn't great but i bet that is a 50 gal barrel)
ú554.40  (554.40  GBP = 918.03  USD)

so about 1000 $ for 50 gal barrel = sounds expensive, wonder what the shipping is?

I have been using the mineral oil from Tractor Supply ($15.00gal) and it really works well with absolutely no smell. Today I went to Wallyworld and purchased 12pts @ $1.68/pt = 1.5 gals for $20.16. Not tooooooooooo shabby considering the looks I got at check out.......

United Oil sells mineral oil: 10 gallons $78.00 with two buckets. If I supply the buckets its $10.00 less. I'm not sure if its a national company. This is comercial minerial oil. Its my understanding that food grade is the same but is proccess in a clean room enviroment.

had 55 gal barrel delivered to my house. just used two planks to roll it off the truck. cost of white mineral oil and delivery $13 per gal.
I want the food grade thickness 70. tried 90 but too hard to recycle through the paper bag. white mineral oil has a low flash point, not poisonous.
does not stain. no problem handling slabs with bare hands. other oils can cause  health problems and fires.

When I ask the united oil rep about the mineral oil should I be asking for weight and flash point? Is there any other ? I should inquire about.

Assuming good techinica/food grade an oderless, the best questions would be viscosity (in either SUS or ISO or Saybolt or Kinematic@40C ...) and the flash point in either F or C.

I've been getting these specs for light mineral oil:

Kinematic Viscosity @ 40 degree C......... 14/18
Flash Point ........................................... 170 C min

Also read that mineral oil is a by product of gasoline and it cost the refineries more to dispose of it than to sell it. Question is why don't they just give us some for our saws and charge us shipping only?

yes, they should give it to us!!

sounds like you are getting something like Deakeol 9 on this chart (http://www.hollandchemicals.com/Documents/Ctrl_Hyperlink/White_Oil_Specifications_and_Applications_uid62320091115061.pdf )

This is also another good chart for seeing how different viscosity measures compare.

SInce this company is just a few states north, I asked them how much for 1-gal and 5-gal of theri Drakeol 7 and 5. It seems that the lighter the oil, the lower the flashpoint. I would hate to get oil that needs cleaning less often, but which burns me to death. I will try to stick to flashpoints above 300 F.

So this is what I came up with for flash point 419 f
Kinematic is 40 c @ 23.5

How does my oil compare to others? I'm  thinking a higher flash point is good but have no Idea what Kinematic viscosity is or how it pertains to cutting rocks.

If you look down the 2nd viscosity column on the chart I linked to, you see that is about SUS 120, or comparable to their Drakeol 13. It is a little thick compared to SUS 70. I think it would qualify as a medium mineral instead of a light - or maybe right between the two.

The reason thinner is better (as long as flash point does not get too low) is because particulates will settle out more quickly and you get less thick rock pudding. Possibly have to change oil less often. Oil might filter faster. Likely have less grit dragged back into the cut by dirty oil ... etc. But other factors like blade quality, kerf wider than core, depth of oil in the tank, whether the oil is pumped onto the blade, and others, might make more difference than getting a slightly lower viscosity.

I'm not going to throw out my STE-70, but I lose a little each time I clean and filter, and if the price is right, I will replace with a lower viscosity if I can get it.
