My MS210 uses less than an oil tank for each fuel tank, not lots but less. I have a MS310 but have not used it much so I do not know the bar oil consumption. I always add chain oil after adding fuel. 
As a quick audit I start up the saw and rev the engine a bit while the bar tip is pointed at a clean piece of cardboard. If I see a bit of oil slinging I hope that it is enough oil. Note of course that different brands of bar and chain oil have different flinging characteristics. I used Stihl oil for a while with the new MS210. I got some Tractor Supply oil and fussed that it was thinner. As little as I cut I have a while longer before I get back to the Stihl chain oil.
