So when winterizing this weekend - I pulled my thermostats out and drained the motors and ran the -100 through. My dock neighbor warmed the engines up - they were plenty warm and then ran the -50 through. We were talking and he said - I am sure things are okay for the winter. I said lets pull some drains and see what it looks like. His engine was light pink on every drain. This was after running 8 gallons through a 454 - crusader. So I mixed some pink and water just to try and match the consistency. My best guess was that it was 70% water and 30% antifreeze. The only part that was pure antifreeze was the mufflers. My 350 Mag took 6 gallons before it was spitting antifreeze through the exhaust. I know lots of folks don't drain the engines before they winterize. But I was surprised how much it was diluted. We ended up draining his motor at that point. He normally left his engine drained anyway. Just an observation that hopefully will benefit someone.
