I asked this question last summer, but I don't understand the answer. When I bought my saw (Lortone ST-10), it was full of clean oil, but I don't know what type of oil. When it got dirty, I removed it and filtered it, but there's not enough to fill the saw. I replaced the oil with mineral oil, and didn't mix the two because I was advised not to. I still have a jug of the old, unknown oil that's cluttering up my garage and I really want to use it in my saw.
So my question is, what will it hurt to mix two types of oil?

If it's just a gallon I would probably just turn it in to an auto parts store that takes used oil. For $20 I would not bother mixing oils. You never know if it's hydraulic oil or something like that.

I've been using mineral oil in my LS12, picked up a LS10 that had ?, kinda golden in color, cleaned and sold the LS10, and then needed more oil the next time I emptied the LS12, so i added maybe 2/3 gal of ? to the mineral oil. After a couple days of use, it seems like the oil is thinner than just mineral oil. In the future, I will not mix, just gonna stick w/ the mineral oil. Then again, It could be the 100 degree days... Damn it's been HOT!

It sure would be nice to know what kind it is. I used Shell Pella in my big saw and the guy I bought it from had some Almag or something from Texaco. I ended up adding the Texaco to the Pella with no issues. If both are mineral oils they should be OK. Does the filtered oil have a strong odor? Different odor than the mineral oil you are using? If it was a vegetable based oil you would not want to mix it in for sure. Pella has a really strong odor. Hydraulic oils less so. Most highly refined mineral oils have very little odor. The old timers used all kinds of mixes of diesel and kerosene which have pretty easily recognizable smells. I wouldn't mix those in or use them (except maybe to clean car parts).

Unclesoska, low viscosity is a good thing. Maybe you made your own "multigrade" oil.

It did have a stronger odor than straight mineral oil. Maybe hyraulic. It's misting alot, but again 100 heat. i do like the sound of "Uncle Soska's Multigrade", it has a kinda organic ring to it.

My mystery oil is yellowish and has a very faint odor, but it's not a bad odor. My mineral oil has no odor.
I think I'll take Chuck's suggestion and dispose of it. I just wasn't sure what could go wrong by mixing. Thanks everyone.

Like Fossil said... Probably just saw oil that has been filtered. I wouldn't mix in an unknown, if both oils are known it's not an issue.

There is a pretty good oil called "amber neutral". It is kind of straw colored with very little odor. If you are talking only one gallon maybe easiest to just dispose.

Yep, it's only about a gallon. Thanks though!
