Not all ingredients are required to be listed on an MSDS. I'm not saying that these fluids are NOT the same, but simply saying that they may contain more than what an MSDS shows. Look at any MSDS for motor oil. It likely just indicates heavy petroleum distillates or similar. None of the other additives (like sodium, boron, etc) are listed on an MSDS.
