Used motor oil for bar oil??

Not enough data, he may do other things that shorten the life of his saws.

 

But slinging out petroleum bar oil is? Both are doing the same damage to the environment.

 

Not much, oil is designed to keep the engine parts from deteriorating. Unless someone allowed the oil to stay in the engine so long that it broke down to the point it was no longer lubricating. The main containment would be the wearing of the bearing surfaces which does happen over many tens of thousands of kilometers. There could be some chemical changes in oil that has been overheated by long periods of high speed driving over many months.
I drained the oil from the Old Girl into some plastic jugs. The Old Girl is not operated that often and the oil looked almost new. I have used it in the little Echo saw because I ran out of bar oil.

 

That is true; however, we are breaking it down much quicker so it goes into the atmosphere much quicker and thus builds up quicker than nature can handle. However, that is for a different topic.

 

Is it still used in brake pads? I thought brake pads used a different material; still going off topic though. Don't forget about all the sulfur oxides from car exhaust that forms sulfuric acid when it mixes in with the moisture in the lungs.

 

Not very well but irrelevant to the bar/chain question because the tolerance of the chain in the groove of the bar, speed etc is not the same. While engine oil might can work quite well in two different applications that does not mean that bar oil can work in the same two different applications.

 

I forgot the smiley!

 

Okay, I'll try. You have rings on the cylinder/piston that cause the compression. When a engine wears you get blowby past those rings. What's on the other side of the rings? Oil. All that nasty stuff that normally goes out the exhaust pipe slowly into countless air particles, starts getting put into the oil, in MUCH higher concentrates. This(ring/cylinderwear is why older engines loose power and the oil becomes blacker quicker than a new one with tighter tolerances. Oils job is to lubricate and a side job is to clean if you will. Remember leaded gas and other things? Guess wear it builds up. It's been my experience that people who use change oil in their saws normally don't work on their saws.

 

I would guess, no data, that the total number of humans farting produces more methane than the number of neat cattle

 

It has more to do with their digestive system and the quality of forage they consume.

 

Not my Sequoia bigger than its era tahoe

 

Yep the heavy metals that come out of the metalk like engine bearings and other byproducts of combustion and such.

 

That's my point , someone who doesn't care enough to use bar oil probably does more neglect as well, it's just a coincidence and how ones overall attitude toward maintenence and care

 

My experience is not matching what people are saying. I had my old 046 Stihl that I bought in 1994 and retired in 2016 and never had the oil pump replaced. The engine lasted a long time too, and while I did not exclusively use 2 stroke oil, I occasionally dumped in NEW 10-40 into the gas when I was in a pinch. This is a commercial grade saw and used commercially...in other words I did not just leave it in the corner for years upon end and make these claims.

Now perhaps I just skated by without an issue, or perhaps it does not matter as much as people think; as Kimberly says, I think there are too many variables to say.

 

I disagree. They cannot even enforced half the laws they have on the books now, much less pay for forest rangers to go around and check land owners and loggers. I have not had a forest ranger show up on my farm for over 7 years and I roll over my forestry permit every year.

In order to ban bar and chain oil they would have to ban all spills everywhere and that is just not going to happen. Common sense says a little spillage is going to occur and that has to come without repercussions. If I am consuming 1/4 of a gallon per day, that is the same amount we were allowed to spill into the coastal waterways of Maine when I worked on the Tug Boats and all without notifying the coast guard. The coast guard does not want to be notified of a 1 quart spill and be bothered with it any more then a forest ranger wants to be bothered with checking bar oil tanks on peoples chainsaws.

 

actually if you research the subject, there is a lot of data confirming this.
And again I have cut 10 cords in the last 10 years so my used motor oil has done less damage then your new bar oil.

 

It is still used in MANY products, in some applications there is nothing else that will work. In some instances it is from products overseas that have little regulation.

 

Your missing my point. Laws are laws wethe they have 100% compliance or not. It would be a secondary violation, meaning they don't go after for it specifically . Take seatbelts. for example in this state up till a few years ago they didn't go after you for not wearing one. If you were speeding and they saw it you got a ticket, but they didn't ride around stopping seat belt violators. Or my hunting license. In like 20 years as a licensed hunter I have shown my license 2 times and never on my property. That doesn't mean I don't need one on it though . No one checks how many deer I kill either, that doesn't mean it's legal for me to kill bucks a day or 25 a season, its mostly self policed, and they go off tips of folks that anonymously tip othwrs. In this case if you cut on someone's land and they saw used oil, they could report you for it, or a saw shop that worked on a saw for you?? Speeding is also the law, but we all know you get by with it 99% of the time, does that mean it's not enforceable? Died fuel, many in farm country have had tanks dipped, othwrs never, does that mean that they cannot enforce untaxed fuel? They cannot see it in your tank and have no idea, some officer has to just randomly dip you to find that one. I think this is a very similar situation .

So I would agree, they can hire new Rangers to go check and enforce bar oil laws, but would they do it if called or on a site inspection of one was ever made....yes.

And I am not arguing for the ban of clean new B and C oil.

 

Hence the "Extrapolate what you will".
