I understand there are environmental and legal controls regarding this, but prefer the internal engine conservation properties of ethylene glycol over propylene glycol. To comply with these restrictions, I start my diesel before Spring commissioning on the hard - after using the engine's water pump to draw fresh water out of a 5 gallon onboard bucket - indirectly filled by a garden hose.
I collect the green exhaust liquid to a bucket by way of a hose inserted to the wet exhaust outlet. I remove the hose when the liquid turns clear and then dispose of the liquid at the marina's toxic substance collection shed.
I do also realize though, that this thread concerns winter sailing while the boat's in the water. So, do not use the toxic stuff in this instance.
