Sail Delmarva: EG vs PG: Conventional Wisdom That is Provably Wrong
It's not the environment that concerns me, I would still dispose of properly no matter what I use. My concern is with possible leakage into the hot water heater.
I have only had our boat for just over a year, and up till now have been topping up with the green auto coolant. Recently I noticed green slime oozing out of the hose next to the thermostat. I then read a post on the leopard
forum about using the correct coolants for the Yanmar engines to prevent any kind of corrosion
especially to the aluminum
bits. My last boat had a Perkins
, and using the green stuff was no issue.
The Banfrost is relatively inexpensive too.
Thanks for the blog article, this helped me understand the differences between PG and EG
I also want to make sure I use a coolant with all of the inhibitors to protect my engines.
