So got my order from MTP. It came with a free gift so I picked the shellfish oil. Does shellfish oil freeze? It was -10F last night. Just don't want to leave it in the garage if it will freeze. And don't really want it in the house in case it gets broke=mad wife.
Also how does everyone use this? Can you dillute it then use it just like fish oil?

Don't have to add much shellfish oil to your fish oil to make it smell stronger. I put 1/2 to 1 cup shell fish to one gallon of fish oil. Don't know about the freeze temp

Yep, gets cloudy looks an smells normal when it warms up i mix a tablespoon or two with a half gallon of ground fish Been awhile since we had below zero temps here

I once got what I considered pure shell fish oil. The stuff I got, that I feel was pure, was labeled as a flammable liquid and was in a steel can. The stuff you buy in a plastic container is already cut, with what and how much who knows. Most people would not buy pure shell fish due to the price. It seems like it was $200 a gallon 15+ years ago. It is synthetic, not a real oil from shell fish. It seems like Nick Wyshinski had it formulated off the top of my head.

Would it freeze hard enuf to break the 4oz lure bottle it came in?

All depends on what it's cut with.
