Bar Oil

[Yander]

I asked the guy I hire to remove trees around my buildings what bar oil he uses. He said the oil he drains from his truck and has for years. And he has a big assortment of Stihl saws in his fancy truck including an MS500i. Just saying.

My dad also used, used oil for several decades, cutting wood. No issues except I stopped using it due to the mess it makes as it slings back onto your clothing and if you spill it on yourself when refilling. But I don't use much bar oil, so $$ is a non-factor.

I use used motor oil. Yes it's thin but they charge too much for bar and chain oil.

Priced a replacement bar and chain recently? One year I put used oil into my saws. The next year I had to replace the bar and chain on both.
Motor oil doesn't contain the sticky compound required, so it just slings off before getting all the way around the bar groove.

I've been using Great Value soybean oil. Get it in the gallon jugs at WalMart for very cheap vs the very expensive Stihl Eco Bar Lube which is exactly soybean oil. Haven't had any problems yet.

This is what I was going to suggest. When it's really cold, I mix some canola cooking oil in with regular bar oil. Seems to work well for me.

FYI all petroleum based oil is a carcinogen, my father used used motor oil from our vehicles in his Homelite super xl that went 30 years. I used it in my Homelite 330 for 20 years and now my Jonsered for 15 years and have had no issues. I replace bars maybe every 10 years. It is free and recycles oil rather than consumes more.

Are you drinking it? Oh... you get some in the cut and burn it? Give me a break.

Guys handling used engine oil were getting ski cancer.

Why Used Engine Oil is a Concern

• Carcinogenic Agents: While unused engine oil has a low risk, the process of running an engine creates polycyclic aromatic hydrocarbons (PAHs) and other combustion products which accumulate in the oil over time. These PAHs are known carcinogens.
• IARC Classification: The International Agency for Research on Cancer (IARC) classifies used engine oils as a Group 1 carcinogen, meaning it is known to cause cancer in humans.
• Specific Cancers: The primary cancer linked to dermal exposure is squamous cell carcinoma of the skin, particularly scrotal cancer, which was one of the first recognized occupational diseases.

Bar oil is meant to lubricate the chain sliding in the bar groove. The sticker the better IMO. If your bar does not have a nose Sprocket/wheel it will get hot if you don't give it a break once in a while.
If it does have a sprocket/wheel you should be greasing the wheel often with the special grease gun that came with the saw.

There is no need to grease the front sprocket on a bar. I stopped greasing mine over 30 years ago and have yet to burn up a sprocket nose.

You guys jinxed me! Was running out of Blue stihl oil and my dealership was out, so I ran to the locale TSC store and got their brand of winter bar oil. At 10 degrees it ran like molasses....

Never tried it. I just cut with diesel.

But wonder is their TSC winter weight listed at 10w or 20w? I was at RK and their winter BO was 20w.

I always thought winter BO was 10w least ones I seen local.

I seen it there beside it to left in pic and never checked.
