When I ran the pink stuff through the engine I purposely left a puddle of it in the exhaust and plugged the exhaust port with a rag so no rain water, etc would get in and dilute it. At least then I knew that what was sitting there was a fairly close sample to what was sitting throughout the engine components. I figured it would be an easy way to check out the consistency of the stuff if we got into some real cold weather.
When I pulled the rag out and looked in it looked like “solid” pink ice
