Default Used motor oil as chainsaw bar lube

I heard somewhere that it is OK to use old oil for your chainsaw , should I filter it first or just use it as is

I would think that it would be too thin...based on the fact that chain lube starts out around the consistency of gear lube and motor oil starts around 30wt and is then thinned even further with gasoline mixed in after use. Wouldn't worry about filtering. Probably make a mess but give it a shot and let us know how it goes.

Be careful where you point that thing - the oil is going to get flung off the bar and go all over the place.

I'll agree with the " . . . something is better than nothing . . . " and use used motor oil, but it will be way thin and fling everywhere. In pinches I've used whatever NEW motor oil I've got laying around and it makes a mess. For the cost of the real-stuff and the hassle of filtering used motor oil, unless you can't get any bar oil or gear oil, it would not be worth it to me, but it can be used.

Use gear oil if you have to but not motor oil. It's too thin. Never mind the dirt you're pouring into a 600 saw. Chain is what, 30 bucks a copy today?

I have to ask just what is wrong with buying bar and chain oil? LAst I knew it was pretty cheap and a gallon goes a long way.

Take it to an oil change place, they sell it and should take it for free.

You could always mix your oil with gear oil you have lying around; that'll thicken it up.

Don't do it. It will wear both the chain and bar prematurely. Likewise with WD 40 or marvel mystry oil or clean motor oil.

chain oil has sling additives so that it covers the entire chain. They also cover temp range winter and summer weight. If it makes a mess menzizisies will supply a proper absorbent towel to help you contain the mess

You can use sanitary napkins for the clean up?

Who woulda thunk it?

The idea is to dump it over the fence

30 years ago most of the chain saws in production ran about 7-9,000 rpm. Lot's of loggers used old motor oil or mixed it with a bit of gear lube depending on the outdoor temp. The point is the saws didn't develop enough chain speed to sling it and most of the oil stayed on the bar and chain where it was supposed to be. Now however it's a different story. Modern saws such as Husqvarna and Stihl will easily run 12,000 rpm and many of the Husky's tach 14,000-14,500 right out of the box when set to manufacturer spec's. At those RPM the chain speed is well over 60MPH. Regular motor oil let alone used stuff goes right straight off the end of the bar leaving the bottom part where all the pressure is nearly completely without lubrication. As with other..... things.....dry is bad, lubed up is good.

You'll get 3-4 times the life from you bar with the use of a good grade B&C oil. We sell it by the semi load to timber harvesting operations all over Northern Michigan.

Used old motor oil for years in a Stihl and never had any problems. It's just lubing the chain and bar. It is not under any significant heat like a motor is. Never seemed to have a problem. But your probably better off with the proper chain and bar oil...

It will work in a pinch, but definitely not recomended. The best way to see the differience between bar oil & motor oil is to put a drop on your thumb, then touch it with your index finger. When you seporate your fingers, you will notice a string effect, kind of like a thin ribbon of oil through the air between your fingers. If you do this with regular motor oil, you wll simply have 2 oily fingers. If you have to use motor oil, and happen to have either some STP or High Taq oil additive laying around, mix about 3 parts oil to 1 part STP and you will have a really close duplication.
