Saw a reference to this product (see link) in a post over on the RV.net forum (tech issues; extended service coolant). After looking over their web site I remain skeptical, but then again, that is my nature.
Certainly it is an interesting product that may have some benefits, but have questions about viscosity/flow rate issues on the standard cooling system. Purging the system of all existing water “contamination” also seems like a hassle. Then there is the cost; $22.50/gal. Still, in some ways it could be justified between eliminating routine flushes and the improved cooling capacity that they tout. Not planning on testing it out myself, but was wondering if anyone here has any knowledge of or experience with this product.
