This is used engine oil that I removed one of my Marine 4cyl engines last summer .
I didn't have it analyzed, and recycled it.I did pour some in a jar to let it sit for a few day hoping it would separate, water bottom, oil top, but it never did.
I thought it would be interesting to hear what y'all think happened to it or what is in it.I don't know what brand or weight the oil was.
just some background...
This engine oil came from a Marine engine that ran hot, and warped the cast iron head. I am currently rebuilding the engine short block and got the head back from the machine shop. The block was in good condition, but the head was warped between cylinder 3&4. It also had a hot spot on the head gasket between 3&4
