Here are the reasons why you use bar oil.
First because it is what is specified.
Second because modern chain saws are designed arround it.
I use bar oil, but have on occasion used clean engine oil.
I have been arround others who use sump oil.
Proper bar oil, in a correctly adjusted machine will spit very little oil off the end of the bar.....the oil is thickenough and tacky enough to be carried alll the way along the top of the bar over the end..and THEN onto the bottom of the bar.....where most of the cutting is done.
Both my machines, a sthill 029 18 inch bar and a little top handled 12 inch, spit so little oil off the front of the bar you have to look close to find it......but they use most of a tank of bar oil for the tank of 2 stroke..so the right amount of oil is being pumped.
IF I run engine oil, I get a lot of oil spitting off the front of the bar, and I run very close to running out of bar oil, before I run out of fuel.
As for sump oil.....OH goodness no.....Im happy to get coveered in saw dust and chips, and mybe a little oily residue.......but filthy sump oil..no thanks
That is appart from the idea of putting filthy oil into the precision metering pump on a good chain saw.
Don't skimp on either the bar oil or the two stroke.....I buy the sthill branded product in both,,,because it is well specified and it is competitively priced with other quality products.
Remember if the bar is not being properly lubricated, both it and the chain will wear rapidly.
If the engine is not being properly lubricated....it wont last very long at all.
The local tree lopper I use, has acess to plenty of sump oil, with all the machines he has to service.......he uses brand name bar oil...the sump oil goes on tree stumps.

BTW, the NSW forestry used to publish a very good chain saw manual....its out of print, but you will find a coppy in most public librarys.
They turn up frequently in second hand book shops and on ebay.
On the matter of sharpening your chain.......always buy a packet of files, a handle and one of those flat plate guides.
If you learn well you can do as good a job as any machine.
when the old file stops cutting well get a new one.
AND..always wear a stout glove on at least your right hand when sharpening....If you want to know why I show you the scar...ever seen inside your knuckle.
best too to sharpen in a vice with soft jaws.
