A mix for B&C oil

I recently got several IBC totes from an oil distributor. Several have some leftover oil in them, from industrial diesel (train engine) oil to 140wt gear oil. I'm wondering if I could mix it with the summer grade bar oil I have now and it be OK to run in the saw?

 

I would.

 

Thanks, there is probably 5 or 10 gallons in that tote...
Even have a couple with DEF in them...I don't have a diesel truck...

 

Me personally = nope I wouldn't do it.
I know that using something other than bar oil has been discussed here before and some say yes and others no. I just wouldn't do it.

Bar oil can be found around here for six dollars a gallon and you can cut a good amount of wood on one gallon.
I burn wood but don't cut for a living so I can get by with maybe a couple gallons a year so that few bucks spent outweighs the risk and hassle of using something else.

I have spent good money on good saws and for me it's not the risk of causing damage.
Agree or disagree is up to you: but you did ask.

 

They’re are certain properties to bar oil (tackiness/ string ones) that are unique to it. Perhaps you could mix it with some bar oil just to use it up? Otherwise your left with trying to dispose of it some other way. You are fortunate sir I haven’t seen bar oil in my area for $6.00 a gallon in well over a year now.

 

Once and a while it goes on sale around here , I bought two cases last it was on sale from one of my OPE dealers , it was Husky oil. It was $6 a gallon but the only catch was you had to buy it by the case , at $6 a gallon I figured I couldn't go wrong so I grabbed two cases.
Last time tractor supply had a sale it was also $6 a gallon.
So yes lucky once and a while if you shop around.

 

Wy'all...We caught it on sale at TSC last fall 2/$15 or so. Bought 6 gallons, we have just a little left in the last jug. Only sale they have had so far was a $1 off, bought 2 gallon @10.99 each...

 

This is what I had in mind...

 

If it's the lack of "tackiness" that gives you the willies pour a can of STP in it, but 90wt is pretty thick. I have used straight 30wt in a pinch and have never had any catastrophic failures, or any failures for that matter. I will draw the line at used motor oil though. I don't think the guys that use canola oil for milling (toughest cutting there is) do anything to that oil, and that is thinner than 90wt.

 

I would try mixing up a 4:1 ratio, (4 parts bar oil, 1 misc oil) and see how it works and adjust from there

 

As long as the oil is clean. Then like others have mentioned mix it thin.

 

I ran 30w for years 'cause it was a work perk. Mixed some stp in for a tackifier. I still have the bar, the only reason I took it off is I pinched it and broke a chunk out of it.

Edited to add...gear oil stinks!

 

I would mix a small amount and do smear test & drip test, side-side with your bar oil to try & match consistency. I would only mix enough for a tank or two to see if the odor is tolerable. Then go from there on whether you want to go whole hog or not.

 

I'm in the camp of mixing a little in at a time. I've roached a bar using non-specific oil. Expensive lesson learned. I've been using the Bel-Ray bar oil and the stuff is great. It's so tacky I can turn my oilers down a little.

 

Wow that was a great desalination!

 

I meant
Wow that was a great deal.

 

The 140wt gear oil I'd mix with atf to thin it. The others it's hard to say. Like was said, STP or similar will add some "stick" to it. Gear oils have tackifiers made into them to do their job. Clean oil only, no used & you'll be good I'd bet.

 

As far as I can tell, yes, it's clean oil. I haven't pulled any out yet. Tanks were still sealed with caps on. They get the different oils in bulk...
If nothing else, I could have a big bon fire and burn up some trash wood with it...lol
