well first thing is you need to give the condition of the engine, or even check the compression. then you go from there. for instance if there is valve stem and guide wear and ring wear then it will do little to benefit. just put the unit to work and operating temp. will clean the inards out the best. as the wear will accommodate the engine lubrication upstairs, such as valve guides. when you have an engine with tight tolerances as a freshly rebuilt then mystery oil will provide help to the guides. the last thing I would burn in an engine is auto trans oil as it has friction modifiers in it. like an injection pump don't need its very very tight clearances worn due to atf. better off just to add some 2 cycle oil to it. as that is what it is designed for. so if you want to add a little lube give it some 2 cycle oil. just think those power saws run at a high rev. with only a 50:1 mixture. the piston and rings don't need a lot of oil. now that has got me to thinking to get an oil saw and mix 50:1 auto trans and see what happens, and how long it will run.?
