anybody using evans coolant or 100% coolant in their fd

i read up on it and its sopposed to be really good....

Evans NPG™ and now NPG+™ offer significant advantages over EGW coolants and propylene glycol water coolants (“PGW”), which are only slightly less toxic than EGW coolants. NPG™ virtually eliminates overheating (it will never boil-over). When used as a replacement coolant in current systems there is a marked reduction of critical engine “Hot Spots” (the major cause of engine “knock”), increased power and fuel efficiency (From 5% to 15% by extensive company and independent tests). NPG™ also eliminates virtually all cooling system corrosion (i.e.; rust and cavitation (vapor damage described earlier), and it is essentially non-toxic lifetime coolant (tested in excess of 500,000 miles). The coolant base PG is so safe that it is rated “Generally Regarded As Safe (GRAS)” by the EPA, and it is not classified as a hazardous waste. Additional safe operation with an Evans NPG™ system is a result of the coolant operates at a “No to Low system pressure,” (from 0 to 7 PSIG) which means components will not be subjected to high pressure, as is used with EGW, (no “burst” failures) and there is significantly reduced danger of being burned by coolant spray if the cap is released.

There are a few really good threads on the subject in this section and also in the Single Turbo section. I suggest searching for them so you can read all the experiences. It has some advantages - for track use especially. Not worth it for a street car IMO.

I ran it for 4 years until 2 weeks ago.
