just got bar oil at rural king. 5 something a gallon . the only surprise with bar oil was when I bought some cheap chit made out of soap .
Same thing I found. I bought this oil called chain pro from our local farm and fleet. It smelled like drain oil. It worked when it was cold but when it got warm(above 50f) it nearly ran out of the saw.
I use poulan, husky and woodland pro oil. At all flies off the bar, no since in spending too much $$ for it.
