I was wondering if biodiesel would work in our saws. It seems that the old timers would use reg. diesel. Is there a chance of burning up the saw with the oil igniting?
Seems like it would be a cheap alternative to mineral oil but I'm not too sure, any thoughts?

I have used diesel and kerosene before they made it k-1. Biodesel has veg. oil in it , so it should work. Ken

Just curious Geoff,does the bio smell like regular diesel?I would be interested in a cheaper alternative to mineral oil but I wonder if the veg. oil would eventually turn rancid after a while.

I decided to pick up some Chevron shingle oil. I have never run this saw (18" lortone) so I figured I should start with the right stuff. that way if I have problems I will know it's not the oil. I'll check up on the biodiesel soon. Good point about the life of the stuff Mike. Thanks everybody. Geoff

I don't think I would want to put up with the smell. Whenever you play in it you will smell like it for the rest of the day.
Have a great day............Tony

Check on the flash point. Diesel is 130 degrees I think. Bio if vegetable based would turn rancid I'm guessing. My diesel tractor fuel ignites on the compression stroke with no spark plug at any temperature. Something about that low a flash point makes me nervous. I recently heard of a Shell product called "Amberlite" or "Amberlight" and available from Shell distributor for $40 something per 5 gallons. Mineral oils would be better choice for safety. And yes, your saw could burn up and take your shop with it.

That's a good point John. i checked the flash points for mineral oil and biodiesel.
Mineral oil: 275F
Biodiesel: 300F
It should work. i can't see how it would go rancid, it's stored in huge tanks and cars keep it for a long time.

I ran a tank of bio in our boat last year, and the exhaust smelled like you were downwind of MacDonalds. I did not notice the smell when when fueling, but sure did when running..........smells a whole lot beter than regular diesel fuel. BTW, I buy bulk mineral oil to supply our club members, usually getting a white mineral oil that is pharmaectical grade. The last time, I bought oil, there was no white oil available, so I got a naphthenic mineral oil that has both a slight colour, and odor. It is called a pale oil (Hynap 60) In bulk it was $784.00 for 110 gallons, which included the $25.00 state surcharge for bulk oil sales. Flash point is 300F. Woody

I think the diesel stinks, I talked Ken into using mineral oil instead because of smell. If you check with several farm supply stores you should be able to find it about $13-$14 a gallon. At a rock show I noticed they were using baby oil the smell was great but the price I guess if you used off brands wouldn't be too bad. The curator of the museum told me it worked well. Donna

Baby oil is a pure grade mineral oil. I would think you could buy from discount places like Dollar stores or Big lott. The price shouldn't be too bad.

And when they look at you all funny for buying 20 quarts of baby oil, just tell them it's for "wrestling"

The first time I bought a drum of of mineral oil, the oil merchant told me the only difference between food grade mineral oil, and pharmaceautal mineral oil was the fact the food grade had to be packaged in a clean room. Oh, then there is the price difference. I checked the MSDS's for both, and they were identical. I also found out the bulk oil supplier that I get oil from also supplies a major lapidary company that resells the oil for $29.99 per gallon, and they get it for less than I do because they buy a larger quantity.

I've run diesel in my saws for years and love it. The only bad thing is the smell. I use a heavy duty pair of chemical gloves though. Diesel has a high flash point and takes a pretty good flame to get burning, never had a problem one with it as far as usage. Make sure when you buy it tell them it's for offroad use then you don't have to paid the federal government "road tax". I had my newest 18" running hydraulic fluid until I priced it... Holy moly! So back to pump diesel. Also if you use a bottle of STP oil treatment you'll eliminate the "fog" when you open the lid after a cut.
The only drawbacks is:
1. Smell 2. Getting rid of sludge (unless you have a nice burn pile) 3. certain rocks will soak it up and it's a pain to extract from the stones.

I found a local machine shop that cuts metal and they gave me 5 gallons of there mixture. It doesn't rust my blade and it is cool to touch. Don't know what it is but it works great.

Hi,
Vegetable goes through a conversion process to become Biodiesel... thus making it unlikely to become rancid!
However, as an alternative, I too have been toying with the idea of using machine cutting suds. A water soluble machine oil with water, very cheap.
Anyone any thoughts,
Derek
