Want to Know about Grape Seed Oil

I was talking to someone I lift with regularly and play football with and they have some sust that they say is mixed with grape seed oil…it has a yellow/greenish tent to it and he says the green is from the grape seed oil. The thing that bothers me is there is something floating around in it that he says is from the grape seed oil.

Will someone with experience let me know if it is suppose to look like this?
