I've run Evans NPG in a couple of my previous M3's one of which was pushing more boost than was really safe for the engine... That car ran for 25k miles on the Evans before I sold it. It's a fantastic coolant. It runs at lower pressures which is easy on the cooling system, but I didn't want to run it at zero pressure (make it harder for the system to purge air pockets).
I can't fault it at all for what it is. I don't run it on my daily drivers as I do not want the risk of being left stranded needing coolant and not having any with me. Water is a contaminant to Evans coolant. Although you can add water to it in an emergency, I don't like the idea of losing $200 in materials and the labor of having to flush the system again to remove the water.
Instead, I replace the cooling system and rock OEM blue coolant. Yes more expensive, but the preventative maintenance yields much better peace of mind on higher mileage trucks.
