Because every professional user I have ever seen is using 10W30 engine
oil. Now I'm not about to put that into my Stihls but I was just
wondering if I am wasting money on expensive bar oil?

Any comments?

I worked with a professional tree service for 7 years. We used the bar oil
or motor oil . Whatever was available at the time.. Using motor oil never
hurt any saw we had. We used Stihls, we had Huskys, Echos (long time ago).
Never hurt any of them. the main thing is to make sure that the bar gets
oil. Theres a slot that the chain runs in.. sometimes it's good to clean
that out. It can get gunked up a bit. That'll help keep the bar lubed up.
