If I am reading a MSDS safety sheet and see under Ecotoxicity that the product is not harmfull to aquatic organisms what is that saying about the base oils ?

Nothing.

Thanks for the reply but it is saying something when the next lower oil in the tier made by the same company says it " is " harmfull to aquatic life " mineral base oil " and "not" biodegradable

I'm out of time but i'll be back later with what the lower tier oil says about "not" being biodegradable along with being harmfull to aquatics vs the topic oil saying it inherently biodgradable and " not " harmfull to aquatics although that about says it all in different wording

Not arguing Callisa, just trying to figure this out

Understood. I thought your point was that you want to conclude something about the base oil when this remark is done. (e.g. if this remark is done, the oil must be ester based)

Or the lined MSDS has same remark about a particular component .

Clean 7500 is a very nice engine oil for the price .
