Glancing at the amsoil site, looks like the system would be $200+, + effort to install it, might void warranty, and then $38 dollar filters. 200 quarts oil, and 40 filters when spread out over 6-7 years/200,000 miles is more ECO friendly to me.
Those systems can be worth while when your talking gallons of oil in a engine, but not 4-5 quarts, when you get into gallons, sending out samples for testing can even be worth while.
I'm here to learn how to save $$ not the world. Burning E85 in wife car to save $$ and as a plus part of the money stays local, when E85 cost more per mile back to E10.
