Bar oil as fogging oil

My chainsaw calls for about 1 tsp of oil poured into the plug hole when storing for extended periods of time, to lubricate the cylinder walls and rings. I have a giant container of bar oil and was wondering if using bar oil for this purpose would be wise? Per the MSDS the bar oil is 95% 30W oil with 5% tackifier added. I figure the tackifier will help maintain the oil in place on the cylinder walls in storage, like a fogging oil. The oil and tackifier would then burn up when the saw is started. If the tackifier is harmless to the engine, I may but a bit in a squirt bottle and do the same with my other outdoor equipment engines (4 stroke) for storage. I wouldn't feed it into the carburetor as I expect the tackifier may attract dirt. Any thoughts or drawbacks to this?

I wouldn't do that. Tackifier forms a gummy residue upon combustion. Remove the spark plug and add an ounce of XW30 motor oil as it has rust preventatives and metal inhibitors. Pull the rope slowly a couple of time to coat the cylinder walls.

You could use marine fogging oil … stored properly an aerosol can would last for years

Add a can of marine fogging oil to your next online purchase. Starbrite, CRC, Stabil, Quicksilver, Mercury- any brand in an aerosol can with the red tube will work fine. I would not use bar oil !! But some engine oil would also work ok. Fogging oil is a bit thinner, specifically designed for corrosion protection, and made to burn off. Besides my boat I also use it for lawn mowers, boat generator, home generator, chainsaw, pretty much anything with an engine.

Fogging oil in a spray can isn't a really exotic product -- looks like Walmart usually has it.

My 2 stroke oil has fuel stabilizers. What i usually do is before i store them, add a couple of ounces of oil to the tank, shake vigorously..run the machine and see the heavy smoke then dump the fuel..start it again..run it out of gas then store it.

I probably need to do that to my Stihl this week … my wood pile is just 12' from a GFCI plug, and really enjoying my new electric chainsaw

The best fogging oil is a gas (ethanol free) & 2-stroke oil mix of 10:1 Use for any engine (2 stroke or 4 cycle, no matter) Run the engine with a small amount of this fuel, until the carb runs dry. Put it away for the winter. Done. You can use "canned fuel" (like True Fuel) with a lot of extra oil added, and then you don't even need to drain the carb at all.

I tried an experiment and heated a small amount of bar oil in a steel can until it ignited. When the fire burned out I was left with a small amount of black oily substance that won't ignite. This must be what the tackifier breaks down into. I don't want that in my exhaust. I will run the rich 2 stroke mix as was suggested. Thanks for all the input.
