You don't have to get 100% of the water out. Only 97%. Old school isn't always best. If we never made changes and or improvements, we as the human race, would not be where we are today. Otherwise we'll still be using horses, or steam engines, or flathead engines, lubricating with vegetable oils, or rancid petroleum grease. Don't be so closed minded and skeptic people! Maybe the mpg claims are not accurate, maybe they ARE if you read the fine print. But one thing is you can't go through life with you head in the sand.
Please cite your sources for not having to get 100% of the water out. Here are some excerpts from the Evans pages that fueled my statement of 100%...
"Every Evans Waterless Coolant requires the entire cooling system to be drained (radiator, engine block and heater core) and refilled 100% with one of the Evans Waterless Coolants. No need to add anything. Evans now has three different coolants to choose from depending on the application and use of your specific vehicle. Also available is a flush fluid for smaller engines without block drains."
"Evans Prep Fluid is a waterless cooling system flush designed to seek out remaining water after draining the cooling system of an engine."
"Heavy Duty Coolant is a lifetime coolant if it does not become contaminated with water"
Every word of that is directly from the Evans site and tells you that you must eliminate 100% of the water from the system and *keep* it that way.
