I use mineral oil.I dont know what size saw you have so if you have a small saw like a ten inch Walmart or Target is about the cheapest.If you have a bigger one then try someplace that sells horse supplies,they sell it as a laxative in gallon jugs.I would like to know if it could be bought online in 5 gallon buckets,but I havent really searched to hard yet.

Robin: As Mike said, Tractor Supply has it in gallon jugs as a horse laxative.

I bought my mineral oil at Agway for $14.99/gallon. Tractor Supply wanted $18.49/gallon for the same thing.

I use a lightweight tractor hydraulic oil. Much cheaper than mineral oil.

I buy technical grade mineral oil at United Oil, which is an oil wholesale warehouse. Costs $7.29 per gallon, plus a barrel charge. Barrel charges are $5.95 for a 5 gal bucket or $55.95 for a 55 gallon drum. If you bring in your own container, there is no barrel charge.

Robin,
If you are filling the 20" saw you posted elsewhere you will need quite a bit of oil. Fill with water to cover bottom (cutting rim) of blade and either what you fill or drain and measure. That will tell you what you need as far as quantity. Any light weight, high flash point oil will work. You can try tractor places around your area. I know there is (or was) a John Deere place across the river. Tractor hydraulic oil should work fine. Also, I heard of some kind of oil dealer in Lake Havasu City but don't know the name. Covington mineral oil is $65 for 5 gal. but shipping would push up the price. It should give you an idea of price if you can find it locally.

I used hydraulic oil with ok results. Now I use the technical grade mineral that Tony uses and introduced me to. Much better stuff.

I am using an AW32 hydralic oil in my 16" saw with good results. Five gallons was about $35.00 at a local auto parts house. Got it about $10.00 cheaper from my oil supply house.

Calculating oil quantity is not that hard: LengthxWidthxDepthx7.48 = gallons needed (L,W,D must be in feet, so convert inches to feet, even fractional feet. e.g. 3 inches = 3/12 = 0.25feet)

Mineral oil- light or heavy viscosity? Or am I looking at the wrong kind of mineral oil

Technical grade or food grade mineral oil is a light viscosity oil. The only difference between the 2 is the food grade is processed and packaged in a clean environment. Food grade mineral oil is used for lubrication on food preparation machinery, like meat saws, grinders, mixers, etc. Also used as a laxative for animals, mainly horses. Technical grade is used around here for spraying on dirt roads to keep the dust down and some farmers use it to spray on ponds to kill mosquito larvae.
Just thought that might give you a little more help in finding a source for it.

ty, If you don't have a farm supply store near you, then try an auto parts house.The O'Reily's near me has a full line of hydraulic fluids. The AW32 that I am using is a 10 to 12 weight oil. As best as I remember, it cost about $36.

If you can find a place that works on electrical transformers you can get the old oil they take out of the transformers. It's a high grade mineral oil with additives that raise the flash point to above 300 F. Now before everyone panics and says "PCBs! Cancer!" They are required to test the oil for PCBs before disposing it. If it's pre-1975 oil with PCBs then it has to be incinerated at one of two facilities in the US.
BTW. If you are buying mineral oil there are different viscosities. Baby oil is probably the cheapest from a retail source. The perfume smell goes away after week or so. Mineral oil for human laxative sold at the drug store is too thick. It's like the consistency of cough syrup so it doesn't splash off a spoon when taking it.
