Apologies if this has been discussed before, but I haven't seen it. Understood that fuel and gas/oil mixes have a definite shelf life. But does bar oil lose its lubricating properties after sitting for months or years?
Thanks for your help. Have a chance to pick up some older oil locally and wondered...No, not really. Not a lot of volatiles in bar oil, maybe give it a good shake to make sure the tackifiers haven't settled, but it should be fine. Never really been a bar oil snob myself, as long as something is slinging on the chain you're good... we would routinely run canola oil if we were over decks or water features with no issues.
And even if it is in the heat or light, it may still be ok. I've used quarts of 30ND motor oil that came out of floorboards of junkyard trucks and had been there for who knows how long as bar oil.Bio- Vegetable oils go bad. Regular petroleum based as long as it's capped and out of heat/light will last a long time.
I don't think I'd want to use crude oil on my bar and chain, and bar oil is a refined product, so there will be volatiles that will evaporate over time, but yes, I wouldn't be afraid of 5 year old bar oil. 2 stroke mix, not so much, and definitely not gas.If oil can sit in the ground for 65 million years and be fine i don't think 3-5 years in a bottle will make any difference.
Yeah, I kinda knew this since those same veg oils turn rancid in the kitchen. Thanks.Bio- Vegetable oils go bad. Regular petroleum based as long as it's capped and out of heat/light will last a long time.
