Folks, please look to the column on the left of this link for a number of interesting facts regarding mineral and synthetic oils (no, I don't work for Exxon-Mobil): http://www.mobiloil.com/USA-English/...Motor_Oil.aspx
Certainly you check the oil containers to insure it is all of the same batch. That would be the same difference as using a partial container would it not?

+1 to the previous response. Creating a specific viscosity range is not a simple matter of blending different vicsosity oils to make the "new" viscosity. Takes a lot more than simple mixing to produce a viscosity range. The entire process of determining a specific viscosity range involves a lot of proof testing.
Detrimental? Maybe, maybe not. If your bike is under warranty yet, I'd bet mixing your own viscosity "range" would not fall under the manufacturer's recommended practice and they could wipe their hands from a warranty claim. Its not a simple as saying the manufaturer cannot tell you WHICH brand of oil to use.
In a pinch in the middle of nowhere I'd do it, because almost any oil is better than no oil.
Some people mix oil and others don't. Some people use synthetic while others use dino. In all of the oil theads, nobody seems to have a problem with their choice and nothing bad happens. DOES IT REALLY MATTER?

I tried mixing olive oil and canola oil once...didn't like the taste!
3 pages on a simple question, must be winter and an oil thread.
