Am thinking about converting my 91 560 to use Evans NPG+ (non-aqueous propylene glycol) in part as I have some leftover from my F250 dieselís conversion, I know that it is a matter of time until the heat / cool cycles take their toll the radiatorís plastic, and I need to take the car in for repair anyway, so now is a good time; does anybody have experience with Evans NPG+ (using 100% coolant, no water) or any other manufacturer using a dilution (Amsoil, etc)?
Not looking to start a discussion about whether XYZ brand / chemistry coolant is better or worse as I have ready many of them on Ford and Chevy diesel forums, but rather am looking for firsthand knowledge whether the chemistry of NPG will / will not react well with the engine components and / or taking the coolant system to 0 psi (yes, correct, zero) causes issues. I am seeing where some of the folks driving newer MBís are using Evans, but what about somebody with a 560? And, Yes, I do know that conversion to Evans calls for a very thorough flush to get all the non-compatible antifreeze out of the system.
